Chicago Cubs right-hander Marcus Stroman committed Major League Baseball’s first pitch-clock violation in the third inning of Thursday’s opening day game against the Milwaukee Brewers. With no outs, rookie Brice Turang on second base and Christian Yelich at the plate, plate umpire Ron Kulpa called the violation on Stroman at Wrigley Field. Kulpa pointed to his wrist in announcing the call, and the automatic ball made it a 2-2 count against Yelich. Cubs-Brewers was the fourth of 15 opening day games to begin Thursday. Several more violations followed on the first day of regular season games since MLB introduced a slate of rules changes this season.
