The regular season's still coming, and the Boston Red Sox are still trying to figure out the back of their starting rotation. The front three are all set. The back two are less set.

The latest, from Alex Speier:

Starting candidates, he confirms, are bard, aceves, cook, doubront. Miller ready to start long toss again today.

Vicente Padilla is out, and Andrew Miller is out. For now. Thursday, it was suggested that the favorites are Alfredo Aceves and Felix Doubront, with Daniel Bard returning to the bullpen. Nothing official has been determined, but that's the state of things, allegedly.

As we've mentioned, this is just about the rotation with which the Red Sox start the year. That rotation can and will change as the season progresses. Miller could re-emerge as a candidate, as could Padilla. But people place a special significance upon season-opening rosters, so, this is an update on the Boston Red Sox' possible season-opening roster.
