Lefty reliever Craig Breslow is likely to start the season on the disabled list, Red Sox manager John Farrell said.

The same could be true for another lefthanded reliever, Franklin Morales.

Breslow arrived in camp with weakness in his left shoulder and has only recently started throwing on flat ground. He is not close to getting on the mound.

Hes on an every-other-day throwing program right now. Its hard to project right now that hell be ready to go once camp breaks. Hes going to need a little time," Farrell said.

Once he starts throwing off the mound, Breslow would have go through the process of throwing live batting practice several times before getting into games.

Morales threw one inning in a game before being shut down with lower-back pain. He responded well to anti-inflammatory drugs and played catch today. The question now is how quickly he can catch up.

"Depending on how these next probably 5-7 days go and how he can pick up on the throwing program, that's going to give us better read on whether he's going to be ready to go," Farrell said.

That will leave the Red Sox with one lefty in the pen Andrew Miller instead of three. But righthander Koji Uehara has been remarkably effective against lefties in his career (they have hit .216/.248/.383 three against him).

"Fortunately we have depth and we have quality depth in the bullpen," Farrell said.

With Daniel Bard likely ticketed for Triple A to continue working on mechanical issues, the Opening Day bullpen now projects to this:

Closer: Joel Hanrahan
Set-up men: Andrew Bailey, Andrew Miller, Koji Uehara, Junichi Tazawa
Long relievers: Clayton Mortensen, Alfredo Aceves
