Mike Trout served as designated hitter for the Los Angeles Angels on Thursday in his 1,000th Major League game.

"Obviously I want to be out in center," Trout said, "but it is what it is."

Trout has a sprained right index finger that is affecting his ability to throw, according to the Angels. He will be re-evaluated "in a few days" to assess when he can return to center field.

Trout thinks he injured his finger while playing in Oakland last weekend but that he can't pinpoint when or how the injury occurred.

"I think it was just over time," Trout said. "I don't know one spot when it happened, but it's pretty painful."
