I think his power decline is most definitely due to a combination of injuries. He came into the season with the thumb being an issue, but it didn't seem to be affecting his power too much early on. In his first 18 games, he had 6 home runs, including a 3 home run and a 2 home run game. I know he started developing some blisters because he wasn't able to feel how tightly he was gripping the bat, but he was able to deal with it. I think once the abdominal muscle became an issue, that's when his power really started to decrease. Hopefully, that has subsided, and judging from his hitting the last week and a half or so, it may be a thing of the past. He's started pulling the ball to left field with some authority. It's not a stretch to think he could end up with 25 home runs if he stays healthy.
