Earlier today we heard that the Indians are in "serious talks" with Mike Cameron and Andy LaRoche as they seek bench help, but MLB.com's Jordan Bastian says (on Twitter) the team still hasn't ruled out adding pitching yet. He wouldn't be surprised to see them add a reliever before Spring Training.
Cleveland's rotation is pretty well set with the ground ball heavy quartet of Ubaldo Jimenez, Derek Lowe, Fausto Carmona, and Justin Masterson, plus they have Josh Tomlin, Jeanmar Gomez, and David Huff to battle it out for the fifth spot. A free agent like Andy Sonnanstine or Clay Hensley could provide both rotation and bullpen insurance on a minor league contract, though that is just my speculation.
