For a guy who arrived in camp with tendonitis in one finger, then sliced open another with a fishing knife, Jake Peavy insists he feels as good physically as he has since leaving the San Diego Padres in 2009.

Honest.

"I was never this healthy in Chicago,'' said Peavy, who spent three full seasons, and parts of two others, with the White Sox before being dealt to the Red Sox last July 30. "A.J. [Pierzynski, a teammate in Chicago and again here] hasn't caught me with this much [good] health.''

Peavy added he can't guarantee results because of the improved health; that will come down to execution and other variables. But he's excited about 2014.

"I don't know what it will translate into stuff-wise,'' he cautioned. "But I got traded to Chicago [in 2009] with a bad ankle. I pushed to get on the field, and I was done for the year there. I came back in 2010 and ended up blowing my lat out, which ended the '10 season, which didn't go well. I came back in 2011 as quick as I could, because you want to be out there, but it wasn't the same.

"In 2012, we put together a good year and [I] stayed healthy, but still didn't feel I was anything close to what I can do with the baseball. And then, obviously, [I suffered a fractured rib in Chicago] last year. Yeah, there's no doubt [this is the best I've felt in a while]. I feel like I've got some good baseball ahead of me and I hope to be a big part of this club.
