According to Rob Bradford, Bobby Jenks is headed to the disabled list for the third time this year with lower back tightness. Randy Williams has been called up to replace the reliever.

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.
