“It just remains to be seen how Mike’s hand responds when he starts doing the treatments and his rehab,” Nevin said. “I know he’s anxious to get going. He was happy he could get this done right away so he can get back to the team as quick as possible.”

Trout, a three-time AL MVP, was selected to his 11th All-Star team on Sunday and 10th straight as a starter. He was hitting .263 with 18 home runs and 44 RBIs.

Trout said he had been feeling well before the injury and that it’s going to be tough to miss the All-Star Game.

“I was really looking forward to it,” he said. “It’s frustrating.”
