I agree. Unless he's on a limited pitch count, why not keep him out there for another inning or two and save at least one arm in the bullpen? It probably doesn't make a difference if the score if 7-0 or 12-0, the Twins can't score off of Derek Lowe anyway.
And if he is hurt, put him on the DL. Having him start when he's not healthy isn't doing anyone any good.
