Semi-tough baseball question

Just because enfarcer has managed to post a few on his blog, I have to give the semi-tough trivia question.

Who is the only pitcher that is the career saves leader for two different teams?

(Note: only saves recorded by a pitcher as a member of that club count for each club's list.)

Play nice, don't Google, et cetera.
