Sean O'Sullivan to start Friday for Red Sox

Boston Red Sox pitcher Sean O'Sullivan will start Friday against the Tampa Bay Rays.

What It Means:

He'll get the nod over Clay Buchholz, who will head back to the bullpen for the time being. O'Sullivan allowed just two runs over five-plus innings in a spot-start against the Los Angeles Angels on Sunday.

In three starts this season, O'Sullivan is 2-0 with a 6.46 ERA, 1.70 WHIP and 11.60 strikeout rate across 15 1/3 innings pitched.
