For the first time in MLB history, the All-Star Game on Tuesday featured automated ball-strike (ABS), also called “robo-umps.”
The technology allows pitchers, catchers and batters to challenge a call by tapping their cap or helmet twice. Each team is allowed two challenges at the start of the game and is allowed to keep them if they are correct. Three erroneous calls were overturned in yesterday’s game.
The tech behind it
ABS uses Sony’s Hawk-Eye computer vision system to confirm or overturn umpire decisions in real time. Cameras around the stadium track each pitch’s trajectory, rendering a visual that helped umps make the final call.
ABS has already been used in the minor leagues and MLB spring training.
Fans and players reactions
While the tech promises greater accuracy, reactions were mixed. Nearly 75% of fans gave it a thumbs-up this spring, per MLB.
Some players, like Detroit Tigers star Tarik Skubal, say they may not use the tech but leave it up to the team. Others, like LA Dodgers veteran Clayton Kershaw, want clarity on strike zone sizing.
Other sports are also adopting the Hawk-Eye tech. Wimbledon used the system this year to replace human line callers.
