Red Sox pitcher Clay Buchholz (back) threw his first full-fledged bullpen session in more than 2 ½ months Saturday morning at Fenway Park and everything went well. The right-hander tossed 30 pitches and used each pitch in his repertoire. "I felt good," Buchholz said. "There's no issue with my back, and I felt fine. I'm pretty optimistic about things."
