IF HE CAN STAY HEALTHY!
Martin will be the key player on this Team, because of his defensive work behind the plate, don't forget that he has a Gold Glove at catcher.
He will be the team leader behind the plate that leads the SP, (in particular), but also the BP. The pitching staff will have great confidence in him. Just not having to worry about WP/PB and stolen bases will increase their abilities to pitch. He will provide the 'glove work' behind the plate, that will get the pitchers those extra crucial called strikes, (he will AJ's savior), that have been balls for years.
His offense is not his greatest asset; although he will not be a real slouch there either. He was a Silver Slugger. He will surprise a lot of people, because he has a career high of 21SB, (as a catcher) and has hit 19HR.
The psychological affect on a pitchers of having a CATCHER steal a base on them, (especially at a key point in the game), will be of great benefit to the Yankees.
Definite improvement, at least defensively, over Posada for now.
Let's see if he can keep this up the next two months.
