The reigning American League MVP faces surgery with a torn ligament in his left thumb.
Angles general manager Billy Eppler told reporters Monday that Trout's absence will be longer than a couple of weeks after results of an MRI exam revealed the extent of the injury.

On Monday night, the Angels announced Trout would need surgery. The typical timetable for a return is six to eight weeks.
Trout, 25, suffered the injury Sunday on a headfirst slide while trying to steal second base in the fifth inning of a 9-2 loss to the Miami Marlins.

Trout, the AL's MVP in 2016 and '14, jammed his thumb into the base and yelled in pain as he rose from the ground. He was examined by a trainer and stayed in the game, but was replaced in the sixth.

Trout went 0-for-2 on Sunday and is batting .337, the second-highest average in the AL. He has 16 home runs -- tied with Yankees rookie Aaron Judge for the major league lead -- and is fourth in the AL with 36 RBIs.
