Sure he's always a pitch away from the DL, but the Cubs would probably be willing to move him for a neglible return.
He's just back from a DL stay with "right lateral epicondylitis" ... and, no, I have no idea what that is.
He's got some blah numbers - 4.38 ERA, 1.38 WHIP - but he's also got some intriguing numbers - 10.58 K/9, .628 OPS against.
It's going to take a number of bodies to change over the Reds bullpen. Heck, trade Tyler Pelland for him.
