The Padres traded a pair of AAA pitchers, Simon Castro and Pedro Hernandez, to the White Sox for Outfielder Carlos Quentin.
I am a little surprised that this was all Chicago got, Castro has kind of stagnated as a prospect and Hernandez isn't one, while Quentin has hit 20 HR the last four years while missing quite a bit of time to random injuries.
It's also odd to see the Padres adding salary based on their other moves this offseason, as Quentin is probably due a 2-3m raise in arbitration.
