He hasn't shown any power this season. SLG .300 or so right now. Maybe that dive to 1B is hurting his hand. Kinda stupid if you think about it, they were up 5 runs at the time.
Trying to pull outside pitches is not a good idea. He was hitting them where they were pitch to, but now he's trying to pull it. And sees a steady diet of off-speed pitches down, still could not adjust and lay off them.
