"Earlier, I've been using a lot of top hand," Castellanos explained. "Kind of rolling over pitches I should stay through. Now, with my finger hurt on my top hand, I have to use a lot more bottom hand. It really helped me out tonight.
"I didn't try to do too much."
Castellanos went 2-for-4 with a three-run homer that capped a six-run first inning.
He readily admitted he wasn't feeling as strong as he normally was, but that was hardly evident. In fact, his night was so successful that a reporter asked him whether he might be taking a few more batting-practice grounders off his finger -- the cause of the contusion.
"You know, if I'm struggling, I might have to do that," Castellanos joked.
