The arguments against Jason Giambi — after departing the Oakland Athletics and joining the perennially-vaunted New York Yankees — was that his personality took a hit. He was no longer allowed to be himself. Giambi had to be who George Steinbrenner wanted him to be (which was nothing good; if anything was more evident of Giambi being unnatural in New York, he was always clean-shaven).

Giambi has now returned to the Athletics, and it seems the Giambi of old has returned. Case-in-point: a conversation with Jim Caple…

Caple: They’re talking about making a movie about the book “Moneyball” with Brad Pitt starring as Billy Beane. If they have a flashback scene in the movie, who should play you?

Giambi: I don’t know. Matt Damon is pretty good. I like Matt Damon. Although he would have to gain a little weight.

Caple: Is Brad Pitt a good fit for Billy?

Giambi: I don’t know if it’s a good fit. I think Billy is a little better-looking.

Caple: You’re just sucking up to your boss.

Giambi: I’m just trying to reach my contract incentives.

Classic — and contemporary — Giambi. Welcome back.
