The Boston Red Sox have traded pitcher Kyle Weiland to the Houston Astros in exchange for reliever Mark Melancon, first reported by Jerry Crasnick and confirmed by Ken Rosenthal.

Ken Rosenthal is now reporting that the Red Sox are still in the running for Andrew Bailey and Ryan Madson.

Alex Speier is reporting that Jed Lowrie could be part of the deal, and Rosenthal suggests the Sox may not be done looking for relievers:
