Mike Trout reported to the Angels about 10 to 15 pounds heavier than he was last season.

His increased bulk has drawn concerns about whether or not he'll lose some of his speed, but his manager isn't concerned.

"He's 21 now, so the weight is not a concern," Mike Scioscia said. "You don't know how much a body is going to fill out. He's running great. He feels great. He's not too far from where he played last year. Everything he has is muscle. His body [composition] is still terrific, from what the trainers tell me.

"If a player is 28 and he comes in a little heavier, it's probably more of a concern. These young kids in our lineup are still growing -- particularly the kids from Latin America. They'll start to fill out quicker because of diets and strength and conditioning."
