"I see better bat speed," said Sox manager John Farrell. "You see the bat travel through the zone much more aggressively. There's more freedom. Even in his BP, you see his ability to get to the pull-side a little bit more readily. You see the freedom in the swing pretty clear."
Despite the injury, Pedroia was able to hit .301 last year and play a career-high 160 games.
Of the early slump in Grapefruit League action, Farrell said, "He's just trying to get his timing down. It's just kind of getting back in the flow of things."
