Quality At-Bats with USD Coach Brad Marcelino

Quality At-Bats with USD Coach Brad Marcelino

As the Assistant Baseball Coach at the University of San Diego and a longtime director of youth baseball development, Brad Marcelino is making his mark on both the Southern California and national baseball scenes.

This spring is Marcelino’s sixth season with the 19th ranked Toreros, where he serves as the Hitting Coach, Outfield Coach, and Base Running Coach. From 2013 through 2015, Marcelino coached three consecutive first round MLB Draft picks – including Chicago Cubs All-Star and World Series Champion Kris Bryant.

This past summer, Marcelino was also selected to coach the USA Baseball 14-Under Southwest Region team in the National Teams Identification Series (NTIS) in Cary, NC. Marcelino has been heavily involved in youth development and is the founder of the North County (San Diego) Mavericks high school/college development program, which focuses on development of academics, character, and baseball skills.

Blast Baseball recently sat down with Marcelino to talk about training and how to improve the mental and physical skills necessary for hitters to have quality at-bats.

A MENTAL EDGE

Marcelino’s training methods emphasize developing and fine-tuning a player’s mental approach to the game. Since so much of a player’s performance on the field and in the batter’s box involves extreme focus and discipline, this emphasis helps lay the groundwork for success.

“We talk a lot about the mental side of the game, having a mental edge and performing at the time when it matters most,” said Marcelino. “That’s one of the big things that we do, and I think it really takes our players to the next level.”

Marcelino used his former college pupil, current World Series Hero & NL MVP Kris Bryant, as an example of mental preparation translating to big-time success on the field and at the plate.

“Kris Bryant, and some of these other guys who have been high-round draft picks, they really buy into the mental game,” said Marcelino. “At USD, that consists of visualization for the first 10 minutes of practice, where we take our players through certain aspects of practice and their performance, and just their life. They’re much more productive at practice after we take the time to do that.”

MIND OVER BATTING AVERAGE

Marcelino believes that while starting each practice with mental preparation and visualization is important, so is being willing to accept failure – at least by the conventional measure of success vs. failure, a hitter’s batting average. Baseball is not an easy sport. Understanding and accepting that it’s hard to get hits at any level of the game is key to a strong mental approach.

“We stress from day one that we’re detached from any batting average,” said Marcelino. “You have to understand that you can do everything right in a batter’s box, and on that day, your average could go down. Getting that ingrained into the hitters early, when they first arrive, is huge. You can’t base your success on average. You have to base your success on quality at-bats, which is a big deal for us.”

Just as Marcelino stresses to his hitters not to get caught up in batting averages, he cautions them not to fall prey to the concept of “being in a slump” when a hitter is not putting together quality at-bats.

“I’m the hitting coach, so obviously I hate that term,” said Marcelino. “We make adjustments and we figure out ways to fix things individually, because there’s certain keys to their individual swing that maybe can get them feeling better. A ‘slump’ is when they’re chasing hits. They’re not controlling what they can control. We have four cornerstones that we build for them when they walk to the plate. We want them to control those parts of the game. If they do that and they’re more stable in their thought process, in their preparation, in their visualization before practice or before the game – then the ‘slump’ goes away.”

AN INDIVIDUAL TOUCH

Pairing that strong mental approach with smart adjustments at the plate is where a hitter can find true success – and start to rack up both quality at-bats and hits.

For Marcelino, this is where Blast Baseball 360 plays a role in preparing hitters for success at the plate. He recognizes that hitting is in many ways individualistic – and Blast can help each hitter build and improve their individual swing.

“There are certain checkpoints that have to happen within your swing, and that’s known, but you have your own individual signature on how you hit.”

“We’re trying to teach guys how to hit, not just how to swing,” said Marcelino. “That’s why I think Blast Motion is so important. You can tell a kid something in so many ways, but now with technology and the way it works, the instant feedback that Blast gives is what I’m most excited about.”

The cutting-edge and easy-to-use technology helps provide that individual attention and touch, according to Marcelino.

“We’ve been doing some one-on-one work with the guys,” recalled Marcelino. “So we put their cell phone on the tripod, and they go into their Blast Baseball 360 app, get into the video recording and we record five or six swings, and we play it back and break it down.”

“It’s great because you tell them one thing as far as their hand path or the bat path and figure out how to fix their launch angle by getting down on their legs more and things like that. But then when you show them and then you record it again and they see the result – that’s when you can connect the feeling with what they actually did and that objective feedback. Each guy has something that is going to click different for him. So, each of our guys has an individual hitting plan, which incorporates Blast.”

IMPROVEMENT STARTS WITH MEASUREMENT

Marcelino added that he has even developed his own leaderboard, which he calls the Quality At-Bat World Series. In his eyes, this is more important that leading the team in batting average.

The next step for Marcelino and his coaches is to begin incorporating more and more data from Blast Baseball 360 into these advanced statistics for his leaderboard.

“We’re going to look at their Blast numbers,” explained Marcelino. “We’ll look at what we want from each of them individually – from their target bat path to their target energy transfer to their target swing speed and exit velo. With all the numbers that Blast provides, we know they’re taking a good swing when those are consistent. That’s what we want, number one. We want them to step in with a clear mind and get their best swing on. That’s where Blast makes on impact with our players.”

Blast Motion Approved for In-Game Use

Blast Motion approved for on-field activities and in-game use

Blast Technology Approved for In-Game Use
With the baseball season opening day upon us and the recent launch of the Blast Baseball 360 next gen app, it’s time to play ball! In 2016, Blast became the Official Bat Sensor Technology of Major League Baseball and for the 2017 season, we have been approved for in-game use in the complex leagues, which are the Gulf Coast League and the Arizona Summer Leagues (Minor League). The players assigned to this level are first-year players who are drafted into the MLB. As in 2016, we have also received approval for on-field use.

MLB, Teams, and Players Benefit from Blast Sensor Data
Blast has developed the most consistent and accurate swing analysis sensor in the market. Through an independent study completed by the Center for Human Performance, the Blast sensor delivered industry-leading results. And, when you’re working with the top athletes in Baseball, accuracy maters. (Center for Human Performance case study) By using bat sensor technology in-game, players, coaches, and front office personal will be able to gain new insights into recently drafted player performance through objective data (metrics). Armed with this data, MLB teams can create player profile baselines and begin to see how a player’s performance changes between practice and in-game situations. This also allows the teams to make validated comparisons between the rookies and their franchise players. Teams can start correlating various factors that can affect a player’s swing including stress, home / away field, weather, and other variables.

With teams using Blast sensor data to make better draft decisions at the amateur and now, rookie level, it’s clear Blast technology is changing how a new generation of players are being developed, assessed, and recruited, creating the standard for performance in the big leagues.

The Next Generation of Blast Baseball 360

At Blast, we know the daily drive to improve starts with the right tools. We recently launched the next generation Blast Baseball 360 app (available in the App Store and Google Play), giving players and coaches a new toolkit to train smarter and get better.

The update brings a very different look and feel to the app. Our own Armando Santana, Director of Product Management, and Julia Putzeys, Product Manager, provide an in-depth look at the new features and functionalities, along with the inspiration behind the update.

Experience the Difference

After extensive research, feedback, and testing to see what players and coaches wanted out of Baseball 360, our team found several ways to improve the overall experience.

“We have an amazing technology in our sensor, and it’s something that’s super valuable to the people who are using it to train and be better in their sport,”said Putzeys. “But really, that’s not helpful to them unless they have an app that goes with it that is just as great. It needs to be easy to use and perfectly showcase all the functionality the sensor has, and we think that’s what we’re bringing to our customers with the new generation of our app.”

From a fresh new user interface to enhanced ease-of-use to smarter, faster technology, the update was designed with coaches and hitters in mind, for a quicker path to improvement.

“With our new Baseball 360 app, you’re going to see some general improvements of the interface,” explained Santana. “You’re going to be able to find things easier. You’re going to be able to see where your swings are, where your videos are, where your metrics are, and how you’re progressing. The overall flow fits with the way you’re going to be able to digest this information and train faster.”

From research and development to planning and implementation, many people and perspectives were involved in the new Blast Baseball 360 app.

“Early on, we spent a lot of time talking to our users and our ambassadors,” said Santana. “We have designers on staff who really take that feedback in, and we have these collaborative design sessions. We whiteboard ideas. We work together, then we work with engineering, who is coming up with solutions to those problems that our customers are sharing. They’re figuring out ways we can make this app faster, sync with the cloud, and provide video capabilities that are differentiating features in our Baseball 360 app.”

Users Played a Big Role

In addition to our in-house team, our loyal user base, along with our valued Blast Coaches played an important role in the introduction of this next phase of Baseball 360 technology.

“Our users give us feedback on a daily-basis about how they’re experiencing the product, what they like about it, and also what they don’t like about it,” explained Putzeys. “So we really take that to heart and work with our users. We get feedback from all different kinds of channels – through our customer support team and on the app stores. We also bring a lot of users and ambassadors into our lab and we work with them on the product, and we come up with ideas from there and ways that it can improve based on how they use it.”

“We started with the customer first, and we realized that we needed to build something that worked the way they work,” added Santana. “So we spent a lot of time talking to our ambassadors and pro users, and really understanding how they’re using Blast Baseball today.”

Two Audiences, One Solution

When designing and implementing this update, it was important to keep two distinct audiences in mind:

Baseball and softball hitters of all levels. And their coaches and coaching academies. In the end, we came up with one solution to meet the needs of both groups.

“We’re targeting two different people,” explained Putzeys. “The first is a player that just wants to get better. So we want to provide them with all the tools they need to train on their own, including drills, ideas, and content from our ambassadors to help them get better, then teach them how to use the Blast sensor and our application to train on their own.

“But we’re also targeting coaches who have a team of players that may be using a sensor that they share among them – or each player on the team might have a sensor and the coach is running a practice while using our solution with all of their team members. It’s a very different use case, but I think a lot of times they’re looking for the same results. So, we focused on those main users and optimize a solution that would work for both of them.”

“We wanted to build this app for anybody who wants to improve their swing,” added Santana, who is also an active coach himself. “So the Baseball 360 app needs to be really easy to use, whether it’s the youth coach who is just learning about Blast Baseball and really want to improve a youth player, all the way up to the pro player who’s really trying to take their game to the next level. And it needs to satisfy everybody in between.”

A Bold New UI

A big part of meeting those needs lay in developing an intuitive new user interface – or UI, for short. This revamped UI needed to be not only easier to use, but more enjoyable to interact with.

“We have this amazing solution and we want to have an app that really helps our users use our sensor,” said Putzeys. “We want our app to be fun to use and easy to use, where it makes someone want to pick it up every day and train with it. We want to provide new content for our users and we want to provide an ultimate training experience.”

Training Center + Blast Connect

One of the major improvements is the development of the Training Center, an online and in-app repository for videos and other content that focuses on training and interactive drills. Some of those drills are even offered by luminaries like Blast Baseball Athlete, and Houstons Astros shortstop, Carlos Correa.

The Training Center resides in the main bottom navigation of the new Blast Baseball 360 app – making it easily accessible from anywhere in the app.

“We’ve gotten some feedback on our new training center, which provides something that users have really been asking for,” explained Putzeys. “It’s a place to learn how to get better, and also learn how to use our sensor and integrate it into their training and really get the most out of it. This way, they can make sure they’re using the sensor the way it should be used, and improving on all the metrics we measure. It outlines each metric, along with ways to improve on each.”

This new focus on content-rich training is also fully integrated into Blast Connect, to create the total improvement solution.

“If you’re using the full solution, you get all your workouts and practices from your coach, you can access them on your mobile phone, and you can complete the workouts and practices while you’re on the go” said Putzeys.

“With the new Blast Baseball 360 app, coaches and academies can expect some improvements on how we have integrated with Blast Connect,” said Santana. “Coaches can capture swings and videos and sync that to the cloud, then they can go to Blast Connect and really analyze that information. One of our goals with this new app is to empower athletes to improve and just work smarter. And as they work smarter, they are going to master the game and ultimately enjoy the game more.”

Attacking Bat Path Angle with John Peabody

We recently sat down with  John Peabody to talk about bat path angle, its importance to successful hitting, and much more.

As a former minor league baseball player and the current director of Peabody Baseball, John Peabody is a highly respected and sought-after hitting coach. Peabody works with hitters of all ages and levels – from youth baseball to the college ranks, all the way up to the top pick of the 2016 MLB Draft, Mickey Moniak.

Bat path angle
BlastMotion recently sat down with John Peabody to talk about bat path angle, its importance to successful hitting, and much more.

The San Diego-based Peabody has also teamed up with Blast to serve as a Baseball 360 Ambassador. Peabody is a big believer in Blast’s technology and regularly utilizes Baseball 360 in his training sessions.

Getting on Plane.

Baseball today is awash in statistics and metrics. But there’s one metric that Peabody believes is more important than the others. That metric? Bat path angle – also known as “attack angle.”

“Bat path angle is the angle that you’re attacking the ball at with your barrel, pre-contact,” explained Peabody. “For me, when it comes to Blast Motion, it’s ultimately the most important metric that they measure. I want to know if my guys are swinging up, because I know if I can get a guy to hit the middle of the ball – that he’s going to give himself a chance to hit something hard in the air; hit a line drive.”

“When you’re swinging down on the ball, you’re only on the plane of the pitch for so long. Beside the fact that you’re swinging down on it, the time that you’re in the zone isn’t long. So, your timing has to be that much better (to make up for it). You have to be that much better at hitting the perfect part of the ball with that kind of downward swing. Working slightly up promotes all those things, and gives yourself more opportunity for successful contact.”

Peabody is quick to stress that bat path angle is not “the end all-be all” when it comes to hitting success, but was equally eager to emphasize its importance.

“Making contact with the right part of the bat on the right part of the ball is the other main aspect of it, but the attack angle is huge,” said Peabody. “Being able to be in the zone a little bit longer, whether that be earlier in the swing or later in the swing – makes it so you don’t have to be perfect. You can be a little off, but make contact because you’re still on plane and you’re still in the zone.”

Simple Fixes.

So how exactly does a hitter create a better bat path angle?

“It’s not always that easy,” explained Peabody.

“Sometimes it’s a simple fix, just tell a guy to try to hit a ball a little bit higher than what he’s trying to do. And to do that, most of the time, they’re going to figure out how to get the barrel working slightly up, to make the ball go a little bit higher. There are things that we try to do, as far as getting your top hand under the bat, or getting your elbow under the barrel. Mechanics that we talk about to help get behind the ball or to get on the plane a little bit early – so we can make sure that we’re giving ourselves a chance to work level to slightly up, depending on the pitch location.”

Mechanics and Metrics.

In addition to making adjustments to hitting mechanics, cutting-edge technology is an invaluable tool. By recording and clipping video and measuring metrics like swing speed, time to contact, power and bat path angle, Baseball 360 helps hitters train smarter and get better. It also empowers their coaches, like Peabody, to make changes to attack angles that are less than ideal.

“It helps players and coaches, because a lot of the times, we can’t see that part of the swing,” explained Peabody. “When I’m throwing live to my hitters or I’m working in front of them, I know I can’t see that – especially when you’re working with guys that are swinging the bat from 80-85 miles an hour.

Baseball 360 also helps hitters themselves understand what, where and how they can make improvements to their swing.

“It gives them factual data to whether they are doing what they want to do,” said Peabody. “And I think that’s the bottom line. We talk about wanting to swing slightly up. Well, now you have something that tells you whether you are doing it or not. So gauging the metrics of what’s happening, I think is a good thing. It can be taken too far, but in Blast’s case, to be able to have the sensor tell you whether you are doing it or not, to me, only makes sense to use as a player or to train your players with if you’re a coach or a parent.”

Think Positive.

In addition to utilizing Baseball 360, Peabody runs his players through a variety of drills and exercises during his training sessions.

“Sometimes it takes some time to do these things, but I’ll do anything from high-tee drills to low-tee drills, use pads to squeeze between your bicep and your forearm to help the barrel get flat and get in the zone earlier and stay through the zone a little bit longer.”

Peabody does his best to tailor each set of drills to specific hitters, including when it comes to bat path angle.

“There are some big leaguers that I’m sure have negative attack angles that are successful, but I know the majority of guys don’t. I think when you look at the group of guys that are really the most consistent hitters – and ultimately the best hitters in the world – they’re using their swing to get on base, and you’re going to see those guys with positive attack angles.”

“Most of the guys that I run into that are “negative” guys are trying to figure out how to make it positive,” said Peabody. “You should be swinging slightly up, but swinging slightly up is not the end-all, be-all to a line drive. There’s an art to being on time. There’s an art to hitting the bottom middle of the ball with the middle top of the bat. All those things combined with working slightly up will equal a good hitter.”

Baseball Swing Speed

September's theme for baseball is Swing Speed. We will be breaking down what swing speed is and the importance in this blog post.
We recently sat down with Blast Baseball Manager Justin Goltz and Blast Motion Lead Biomechanist/Algorithm Developer Patrick Cherveny to take an illuminating and in-depth look at a valuable and often misunderstood metric – softball and baseball bat swing speed.

As softball and baseball organizations of all levels continue to dive deeper into data analysis, swing speed stands out as one that many organizations and clubs have yet to truly tap into and benefit from.

Swing speed also happens to be a metric that Blast Motion is uniquely qualified to analyze. In addition to our standing as the official swing sensor of Major League Baseball, our top-performing technology was recently used to measure and display swing speed of players in the 2016 MLB All-Star Futures Game. During that game, won 11-3 by the World Futures Team, the swing speed of hitters from both teams was continuously displayed on the state-of-the-art video boards at PETCO Park in downtown San Diego.

THE VALUE OF SWING SPEED

Fans of baseball and attendees at MLB games are no doubt quite familiar with the pitch speed metric, which is frequently and prominently displayed both on stadiums’ video boards and during television broadcasts. Exit velocity (also known as batted ball speed) is also becoming a more commonly cited and displayed metric, especially since these speeds at which baseballs leave the hitters’ bats can exceed 100 miles per hour – always a captivating and almost “magic” number for sports fans.

But what about swing speed? Just how much value does it hold – and how does it correlate with more established “speed metrics” in baseball?

“The baseball world has gone to more relevant metrics,” said Cherveny. “It used to simply be batting average, now it’s more about exit velocity, because it takes some of the randomness out of it. If you hit a ball softly and it’s hit away from a player, you may get a hit. In another at bat you may hit it hard but right at a player resulting in an out. The reality is that the more frequently you hit the ball hard, the higher the probability of a successful outcome.”

In a way, it’s really rather simple. The harder you hit the ball, the more likely your chances of getting on base. And the faster you swing the bat, the quicker the ball will leave the bat upon contact.

“Swing speed’s a very important metric, because it ultimately determines how fast the ball’s going to come off the bat,” said Cherveny. “The faster that you swing, the more likely that you will achieve a higher exit velocity, which will more often result in successful outcomes. Major League Baseball has put an increased emphasis on exit velocity and launch angle as two primary metrics for assessing players, and that’s already filtered down to hitting coaches who work with younger players. There’s a big emphasis on trying to maximize exit velocity and launch angle. If you don’t have a high swing speed, you’re going to limit your ability to have a high exit velocity.”

JUST HOW FAST IS FAST?

Unlike exit velocity or pitch speed, swing speeds of elite baseball players don’t approach or exceed triple digits. In fact, truly superior swing speeds don’t even come close to reaching 100 miles per hour – at least not if you’re measuring them the “right” way.

“We can confidently say that in-game swing speeds in the 90s or 100s aren’t really humanly possible,” said Goltz. “With some of the data we collected, we see in-game swing speeds in the 65- to 85-miles-per-hour speeds for some of the top professionals in baseball.”

According to Cherveny, the average swing speed in Major League Baseball games is around 70 miles per hour. That might not sound like a lot, but once you understand more about the dynamics behind the metrics, it starts to become pretty impressive.

“We see some swing speeds where people claim that you get into the 90s,” added Cherveny. “That would make sense if it’s at the end of the bat, but if you hit it at the end of the bat, it’s not going to travel as far because some of the energy is lost in the bat’s vibration. So that kind of a swing speed is essentially ‘false.’ Swing speed it dependent on where you’re measuring on the bat. In order to maximize quality of contact, the best hitters want to hit the ball in the “sweet spot” of the bat.

HITTING THE SWEET SPOT

Just as the casual sports fan may be misled about the nature and rate of swing speed, there is likely a good bit of confusion and illusion when it comes to the exact nature of the infamous “sweet spot” on a softball or baseball bat. Cherveny shared more fascinating and illuminating details regarding this renowned but misunderstood sporting hot spot. You might call it the “sweet science” of the swing.

“As a player swings the bat in a rotational arc, the further that you get down the radial length of the bat, the higher the swing speed,” said Cherveny. “So the speed at the hands will be much slower than the speed at the tip of the bat – and where you’re actually measuring is important in terms of what the measurable swing speed is.

“We measure at what’s called the ‘sweet spot.’ We define this is as a point six inches from the end of the bat. The sweet spot is actually defined as the point where the ball will release with the maximum amount of energy to the ball. Scientifically, this is the region in the bat between the first and second bending modes of vibration, which results in very small vibrational modes on impact in this region.

In truth, said Cherveny, the “sweet spot” on your bat isn’t really a spot at all.

“That’s where the best hitters want to make contact, that “sweet spot,” but in reality, it’s not a spot,” said Cherveny. “It’s actually an area along the bat that’s approximately
two inches in length. You can make contact anywhere along that area, and the ball will rebound and come off as fast as possible.”

Even along that “hit zone,” however, every inch matters. In fact, you might be surprised just how much an inch or two can mean, speed-wise.

“Let’s say that at an average Major League Baseball swing is 70 miles per hour, if you hit an inch further towards the hands from that sweet spot, you could lose 2.5
miles per hour,” explained Cherveny. “If you hit an inch further down the bat, it could be an additional 2.5 miles per hour. So you’re looking at around a 5 mile per hour
difference in the sweet spot or sweet zone of the bat, depending on where you hit it.”

MOVING ON UP…

It’s one thing for a young MLB star like Carlos Correa or Mike Trout to whip his bat through the hitting zone with a 75- or 80-mile-per-hour swing speed. But what about even younger, lower-level players?

“At the Little League level, the average swing speed is around 45 to 55 miles per hour,” said Goltz. “For senior league, we’re talking high 40s to maybe low 60s. High school, mid-50s to mid 70s. College and pro, mid-60s to maybe mid-80s. Those are the ranges and averages, but there are a few factors, including the bat size and age, that would affect swing speed.”

“There’s a lot of variables, but the biggest one is just the strength of the athlete,” added Cherveny. “With a more rotational swing, you could have a younger player that could actually move up into a higher swing speed class, but that gets down to the efficiency of the swing. Somebody who has a very rotationally efficient swing can generally produce higher swing speeds than somebody who doesn’t. So you can easily see kids in travel or high school baseball, 15 to 18 years old, who have swing speeds approaching the 80s. We see it all the time, especially working with trainers in batting cages where kids are developing the intent to hit the ball as hard as possible. This is especially true in use cases of tee and drill work where players don’t have to worry about pitch speed and movement.”

One might wonder if swing speed is a metric that’s really even that important for a college, high school or youth travel baseball player. According to Cherveny, swing speed is a very important metric in today’s baseball world. It’s also one that stands to become even more vital (and valued) as the game continues to advance.

“There’s a big emphasis on exit velocity,” added Cherveny. “And as you move up the baseball ladder, swing speed will always be important – not only from how far you can ultimately hit it, but to get playing time at the high school level, to getting recognized and identified for scholarships, and to move up through the minor league system. It’s always going to be a swing-speed dependent game.

“The intent to be able to swing fast is something that young hitters need to have, so that the motor skills become ingrained and they can do it repeatedly. So that when they get to the game situation, they have the ability to actually produce a high swing speed.”

WHAT BLAST DOES BEST

Baseball and softball are difficult and challenging sports. They are also games where mere inches frequently mean the difference between success and failure; hits and outs; wins and losses. Just as it’s important for a hitter to constantly practice and fine-tune his or her swing, it’s vital for Goltz, Cherveny and the entire Blast Baseball team to continually test, tinker, experiment, evolve and practice.

Practice makes perfect. Or something close to it.

“We do a lot of work on accuracy testing, because of the importance of it to today’s game,” said Cherveny. “When you’re trying to actually fuse player input data such as swing speed with ball output system technologies, you have to have confidence in the accuracy of the underlying data. So we do a lot of internal accuracy testing.”

Cherveny explained that a lot of that internal work and testing for maximizing accuracy involves motion-capture technology tools – using reflective markers that are placed on the bat, much as the Blast swing sensor itself is.

“We can then compare directly between our sensor and the motion-capture data for a particular swing for any type of swing across different levels,” said Cherveny. “But we go beyond that in our internal testing for checking the accuracy of our algorithms. We not only look at the speed at impact, but we also look at the build-up of speed throughout the swing too.”

It’s not just internal testing and evaluation that helps the Blast Baseball team fine-tune its swing sensor and out-hit the competition. In fact, a recent external, third-party validation test verified the rarified and repeated level of excellence achieved by the Blast swing sensor.

The test compared the swing sensors of Blast with those of competitors Diamond Kinetics and Zepp. It was conducted by the Center of Human Performance in San Diego, and was overseen by the center’s director, Arnel Aguinaldo. Blast came out on top in several categories, including lowest margin of error (a swing speed average deviation of 3 mph, compared to 5 mph for Diamond Kinetics and 7 mph for Zepp).

“They used our sensor, the Zepp sensor and the Diamond Kinetics sensor, and had players swing in the batting cage to compare it to motion-capture data,” explained Cherveny. “And what they found verified what we have found in our internal testing, that we are the most accurate – 95 percent of our swings fall within plus or minus three miles per hour. We’ve heard from other external parties that have done their own testing and they have also validated these results.”

The test not only showed that the Diamond Kinetics app was not as consistent as Blast in detecting swing readings, but setup time for Diamond Kinetics took between five and 10 minutes – compared to an average setup time of just 90 seconds for the Blast swing sensor and companion app. More importantly, Blast implements a dynamic calibration that allows the hitter to just grab the bat and swing away with no laboratory-like static calibrations prior to each swing. Thus, the batter can use their natural swing style to produce the highest swing speeds possible, which is important for both player assessment and development.

“Blast’s accuracy and ability to not disrupt an athlete’s or coach’s natural routine gives us the best swing sensor solution available on the market,” said Goltz. “We take great pride in the accuracy of the information and data we provide to teams and their players – including MLB clubs.”
