Los Angeles Angels outfielder Mike Trout, the American League's leading hitter, was a late scratch from Sunday's lineup because of left knee contusion suffered on Saturday.
Trout, 20, was injured when he banged into the wall chasing Ben Zobrist's third-inning homer.
The Angels list him as day-to-day, and manager Mike Scioscia doesn't expect him to need an X-ray or an MRI.
"He hit his knee into the wall pretty good," Scioscia said Sunday, according to MLB.com. "He's a little sore today. We'll see what his availability is to do something during the game and hopefully he'll get back in there tomorrow."
Trout is hitting .350 with 16 home runs and 31 stolen bases.
