DETROIT — Clay Buchholz will not come off the disabled list to start for the Red Sox on Tuesday and as a result will need at least a one start in the minor leagues before he does return to the rotation.
The righthander was scheduled to throw in the bullpen on Saturday afternoon at Comerica Park. But lingering discomfort in his right trapezius muscle limited him to throwing in the outfield.
The Sox were hoping for Buchholz to throw 45-50 pitches in the bullpen as preparation for a start on Tuesday against the Rockies.
“Basically what we’re doing is going as tolerated with throwing,” manager John Farrell said. “It’s likely that at some point, we’re probably going to get him out on a rehab assignment, at least one start for now. But there’s no timetable for that. We’ve got to get him on a mound first.”
Buchholz has not pitched since June 8. The Red Sox did not put him on the disabled list until June 18 (retroactive to June 9) because they didn’t believe the injury was serious. Now it’s uncertain when he will pitch again.
Buchholz is 9-0 with a 1.71 earned run average in 12 starts. The Sox are 11-1 in the games he has started.
Buchholz played long toss and did some pitching from flat ground. He told the trainers that he felt “restriction” when he followed through. The trapezius is a muscle at the base of the neck.
Farrell thought that Buchholz would be back by now. But it has been a slow process.
“While he feels improved over [Friday, it’s still a very slight improvement day by day,” Farrell said. “I don’t know that we had a point in time on the calendar where he felt like he’d be back. But we feel like it’s going a little slower than we anticipated.”
