After the game, Dodgers manager Dave Roberts said Miller, who walked off under his own power, will enter concussion protocol.

This year's MLB spring training could prove more consequential than any in years past as MLB will experiment with ABS, the Automated Ball-Strike Challenge System, to ensure the home plate umpire gets as many ball and strike calls correct as possible. On Thursday, the league announced how exactly this new challenge system will unfold.

ABS is MLB’s name for an automated strike zone — also known as robot umps. In a full ABS game, there will be a human umpire behind the plate, signaling the calls communicated through ABS. We won’t be seeing that full system in action this spring. Instead, teams will have a limited amount of challenges.

Chicago Cubs pitcher Cody Poteet believed the 95 mph fastball he threw to Los Angeles Dodgers slugger Max Muncy was in the strike zone

Cody Poteet is going to be the answer to a trivia question one day. The Chicago Cubs pitcher became the first player at the major league level to successfully challenge a ball/strike call using the automatic ball and strike system MLB is testing during Spring Training games this year.

It took just one inning for the Chicago Cubs right-hander to be the first player to successfully challenge a ball-strike call in a big-league spring training game, overturning a called ball from home-plate umpire Tony Randazzo to a strike against Los Angeles Dodgers third baseman Max Muncy.
