FORT MYERS, Fla. -- Boston Red Sox pitcher Daisuke Matsuzaka threw a bullpen session on Monday. However, even though Red Sox manager Bobby Valentine said the right-hander looks and feels good, Matsuzaka is not expected to pitch in a Grapefruit League game this spring.
"His arm feels good. He thinks his mechanics are way off," Valentine said. "He's healthy and he's on that recovery pace that all rehab guys are on. He's on a very good pace. I don't think he'll pitch in spring training."
Matsuzaka was limited to eight games (seven starts) in 2011 and ultimately had Tommy John surgery.
Meanwhile, Red Sox reliever Bobby Jenks dealt with a lot of health issues during the offseason and there are no immediate plans to get him back on the field anytime soon. According to Valentine, Jenks told the Red Sox that he would like to take it "one week at a time."
"That says he's a long ways away from thinking about baseball activities," Valentine said. "He's really had a terrible offseason health-wise. He's a real back-burner guy. We don't expect to see him in any baseball activities for a while."
The right-hander, who was limited to 19 games in 2011 due to various injuries, had two surgeries on his back this winter. He was also diagnosed with a pulmonary embolism last September.
Valentine said he expects Jenks could be a midseason addition.
