In a historic moment during the Chicago Cubs' spring training opener against the Los Angeles Dodgers, pitcher Cody Poteet initiated the first challenge on a ball/strike call in Major League Baseball history. This occurred when Poteet believed a fastball to Max Muncy was a strike, but plate umpire Tony Randazzo called it a ball. Following the new spring training rules, Poteet tapped his head to signal for a review, leading to a reversal of the call, putting Muncy at 0-2 before striking out.

This spring, MLB is trialing an automatic ball and strike system, allowing up to two challenges per game, which can be retained if successful. Players like Muncy have expressed interest in the system's potential for implementation in the future, emphasizing the importance of accuracy in every call.
