The Marlins shipped catcher John Baker to the Padres for pitcher Wade Leblanc.
With Florida, Baker had a 1.7 WAR in 4 seasons and 760 PA. Adjusted for 600 PA, this would be a 1.34 WAR, worth 4 million according to the Halladay Standard. Baker made just 417,000 in 2011, but is arbitration eligible. Baker has a .356 OBP, OPS + of 99, and 04S of 1.825. His Runs Created per Game metric is 5.1, earning a .525 Offensive Winning Percentage. His Secondary Average and ISO aren't that impressive at .254 and .130 respectively. While being an under average home run hitter (1.8%), he is an average extra base hitter and a far above average walker (10.8%), with a decent PPS of 93.48.
Leblanc has a .4 WAR in 4 seasons as a starter, pitching 293.1 innings. Adjusted for 200 innings, this is a .27 WAR, worth $818,275. He should make minimum salary in 2012, which is now $480,000. However, when he first broke into the Majors in 2008, he had a -.8 WAR in 21.1 innings. Since then he has obviously had a 1.2 WAR in 272 innings, which is .88 WAR adjusted to 200 innings. He has a career PE of 2.35 (adjusted PE of 2.66), and SIERA of 4.62. It is really clear that the Padres won this trade over the Marlins.
