What can you really say, at this point, about Bobby Jenks? He's been on the disabled list about as often as he's been off of it for a variety of ailments, and when he's actually with the team, he's not been any good. At the very least I guess he wasn't likely a key component in any of the organization's plans going forward by this point.
Randy Williams is a bit of a surprising choice. A holder of a career 5.74 ERA in the majors, Williams has been quite good for Pawtucket so far this season with a 1.29 ERA and more than a strikeout an inning. Of course, he's had solid minor league stints in the past which haven't led to any success elsewhere, but it's something. The veteran lefty does perform quite a bit better against lefties--though even then he leaves something to be desired--so he could be used in something of a LOOGY role should the Sox choose to trust Franklin Morales with more righties after a few solid innings.
