As ESPN reported, home plate umpire Brian deBrauwere had an iPhone in his back pocket connected to the TrackMan system and an AirPod headphone; DeBrauwere heard the system calls through the earpiece and signaled the ball and strike as usual. On the cross, players can hesitate to override the system if he disagrees with TrackMan's call or if the system fails, something happened during the game. According to The Washington Post, the system was completely cut for half of the fourth inning, during which deBrauwere was called the game that he normally had.
agreed to the calls of TrackMan ̵1; there was a second inning call that struck Joe Terdoslavich who deBrauwere said he usually called as a ball. However, he decides not to overthrow the system and explain his decision to the reporters after the game . "I understand why this is a strike. The top of the ball is shaved under the strike zone," he said, according to the Post. "But it's almost impossible to be consistent with [that pitch without Trackman] because under the zone, but also because the influence of the implication is true."
With a really controversial call and a short outage, the release is generally regarded as a success of all involved – it's uncommon for a number of pitches to be called incorrect during a baseball game, so things that are definitely not worse than normal in this game. It says both players and some players have stated that the strike zone is definitely different than it used to, simply because the TrackMan system is better at discovering some pitches than to people. "The consensus among players and umpires that it tried was that TrackMan tracked the corners of the plate where people could not stop, and grants were higher and lower in the zone," explains Post . But while the boundaries may be different, the hope is that TrackMan will be more consistent.
While the Atlantic League continues to test the TrackMan system throughout its rest, there is no real timeline on when or when the MLB system will arrive – even though league stadiums already have the TrackMan system in place . "We need to see how it works, first in the Atlantic League and then maybe other places, meaning other parts of minor baseball baseball, before it arrives at Major League Baseball," said MLB commissioner Rob Manfred in ESPN.
Data collected from TrackMan is currently used in a wide variety of situations, but in-game pitch calls are not one of them. However, we are good at a time where everyone watching from home can see if a pitch is called a ball and strike immediately, thanks to the tracking system data used in broadcast games. If home viewers can tell if a pitch is a ball or strike, it certainly should not hurt if the umpires have the same information.
