"In the batter's box, he's pressing, I think, a little bit," Angels manager Mike Scioscia said. "It's obviously a long season and he's tired."
Trout has played in 153 games this season, and after he went 0-for-3 with a walk as the designated hitter on Tuesday, Scioscia decided to give him Wednesday off.
"He's played a lot -- this day off is long overdue for him," Scioscia said. "He's just out of sync and he's been grinding it, he just needs a day."
