Mike Trout blasted a 443-foot homer vs. the Mariners to reach 1,000 career RBIs, becoming the third Angels player to hit the milestone.

Trout has been limited to DH since returning from the injured list in late May. He began some drills to prepare for a return to the outfield last week, but felt some soreness in his knee.

Knee soreness and a delayed defensive return point to a larger issue: Trout’s body may no longer hold up to the demands of the outfield.
