The Padres basically traded Maybin (28) for Upton (30)... push at best, I'd think.
Then you figure a salary dump in Quentin, their top pitching prospect, a switch-hitting good OF prospect, and a sandwich first/second round pick... for a closer. Which, he's very, very good... but that's a lot to give for a closer.
I'm rooting for the Pads, I hope it works out for them. I just... seems like a lot.
