The Angels may have lost more than just a baseball game Sunday. They could be without their best player for a bit.

Angels center fielder Mike Trout left Sunday's 9-2 loss in the sixth inning after jamming his left thumb into second base in the fifth inning. Trout dove headfirst while completing a steal of second and tried to grasp the bag to ensure he didn't slide past it.

But when reaching to grab the base, his left thumb became lodged against the bag. Trout immediately shook his left hand and did remain in the game before being replaced in the bottom of the sixth inning.

The good news for the Angels is that X-rays taken on the thumb were negative and it's just a sprain, the team said. The bad news is the Angels aren't sure just how much time Trout would miss before the five-time All-Star and two-time MVP is able to return.

Trout had walked to get on base, marking the 45th time in 47 games he safely reached base this year.
