The Red Sox have changed their rotation again because of lingering shoulder soreness for righthander Clay Buchholz. Franklin Morales will start against the Phillies on Thursday with Jon Lester pushed up to Friday in New York against the Yankees. Felix Doubront is scheduled for Saturday. Buchholz is a possibility for Sunday. If not, it is likely Ryan Dempster would start. Buchholz has not pitched since last Wednesday because of soreness in his AC joint, which is in the collarbone area. Buchholz claimed the soreness developed when he fell asleep holding his daughter. "Clay went and threw a bullpen today. He feels improved but he still feels some symptoms in that AC joint. When he mentioned that, this is something I took out of his hands," manager John Farrell said. "Made the decision to give him another couple of days. He's still a possibility in the New York series. But while he's feeling improved, felt like it would be best to give him a couple of more days as well." Buchholz will throw in the bullpen again on Thursday. That will determine when his next start comes. Farrell said the Sox are "not there yet" in terms of putting Buchholz on the disabled list. Farrell downplayed the idea of Buchholz having more than a minor injury. "The encouraging thing through this is that while he's thrown his bullpens, his arm slot is the same; his delivery is the same, there's no issues with that," the manager said.
