Lance Berkman spoke to Mark Berman about his plans for 2013 and beyond, and it sounds like you shouldn't get your hopes up about him DH-ing for the Astros next season.
"If I do decide to retire my next move is going to be to enroll at Rice and to be a student assistant for the baseball team."
Wayne Graham would be happy to have him, of course, should he decide to hang 'em up because of his bad knee.
Berkman:
"Like I told the (St. Louis) Post-Dispatch, if you put a gun to my head today and asked me what I was going to do 'I'd say I'm not going to play anymore', but certainly I deserve the right to change my mind on that."
UPDATE: Had we not been tearing our hair out, we would have noticed John Royal's story on just this topic back in June.
