"At this stage in their careers".
Posada 2009 splits: 1.013/ .760 OPS
Victor Martinez 2009 splits: .774/ .925
Which is why you need to take into context the home field advantage enjoyed by everyone who hits lefty in NYS, but you already knew that.
Hey, but i forgot to mention, the magical pinstriped uniform keeps "Father time" from affecting Yankee players. Since 2005, Posada has played 624 games to V-Mart's 727, and what's that you used to say about playing time being important when taking into account overall performance when you were using it as an argument against JD Drew? So the fact that V-Mart has better counting stats because he plays more and has caught more games is irrelevant now as opposed to when comparing, say, JD Drew and Bobby Abreu. Some things never change.
