BOSTON -- The Red Sox still aren't sure who's going to start for them Wednesday, but they know who won't: Felix Doubront.
"That starter for Wednesday will not come out of our bullpen,'' said John Farrell.
There had been speculation that Doubront would be given the opportunity for the spot start. Doubront was sent to pitch in relief when the Red Sox were in Seattle last month, and when the Sox began a series in New York last week, Farrell announced that the lefty would pitch in relief for the foreseeable future.
The Sox will need a starter for Wednesday thanks to the Friday rainout which forced them to double-up on starters for Saturday's doubleheader.
"We have a couple of candidates, but nothing yet to announce,'' said Farrell. "We've got to get through these next couple of days to determine who that's going to be.''
On merit, the two likeliest candidates are Rubby De La Rosa, who made five starts for the Sox in June, and Allen Webster, who made seven starts for the Sox last season and had pitched well Triple A this season.
But De La Rosa was scheduled to pitch Sunday night for Pawtucket in Columbus, meaning he'd pitching on just two days' rest Wednesday, eliminating him from the picture.
Webster is set to pitch Tuesday, meaning he could be held out and pitch with an extra day rest.
Anthony Ranaudo, who pitched Saturday, would be going on three days' rest Wednesday. Knuckeballer Steven Wright is slated to pitch Wednesday.
Webster, Ranaudo and Wright are all on the team's 40-man roster, meaning there would be no need to fit them into the roster.
Another complication will come in finding space on the 25-man roster. Barring a release or trade, the Sox don't have anyone in the bullpen whom they could option. One possibility could be to option Tuesday's starter Brandon Workman back to Pawtucket for a time and have whomever pitches Wednesday temporarily take his spot in the rotation.
