Manny Machado of the Padres received an ejection after arguing a third strike: on a pitch clock violation:

Machado was adjusting his batting gloves and appeared to be calling time as the clock wound down to 8 seconds, by which time a batter must be facing the pitcher under new rules adopted for this season to speed the pace of play. Kulpa didn’t grant time, apparently because the clock had already hit 8 seconds, and called him out. Machado stood at the plate arguing with Kulpa as manager Bob Melvin came out. Machado said something to Kulpa and was ejected.

Machado, who was the designated hitter, was eventually escorted toward the dugout by another umpire.

I’m glad umpires are being strict so far. In the past, rules designed to speed up the game were eventually ignored.

This ejection also makes me thing that someone could make a lot of money inventing batting gloves that do not need adjustments.

The Diamondbacks took the game 8-6, coming back from four runs down. Arizona drew seven walks in the game.
