One of several rule changes to Major League Baseball for the 2023 season is the utilization of the pitch clock.
The new rule stipulates that a pitcher has 15 seconds to begin the motion to throw a pitch with the bases empty and 20 seconds to begin the motion with runners on base. If the pitcher fails to begin his delivery prior to the timer expiring, he is charged with a ball.
The violation came in the third inning against the Brewers, as Stroman looked back at Brewers base runner Brice Turang, who was leading off second base. As Stroman turned to deliver the pitch home to Brewers outfielder Christian Yelich, home plate umpire Ron Kulpa called the violation on Stroman.

The 1–2 count went to 2–2 upon the violation of the rule by Stroman.
