The return of in-game video in 2021 has benefited many players, and one batter in particular may end up benefiting quite a bit.

Boston Red Sox designated hitter J.D. Martinez admitted Monday that the return of in-game video reduced his anxiety because it allows him to make adjustments at-bat to at-bat.

Major League Baseball banned in-game video during the shortened 2020 season and reached an agreement with the players union to bring it back in 2021. 

Martinez has long been an advocate for using video footage to understand why an at-bat went the way it did.
