This move has to happen. Posada has been relegated to backup DH duty. Nunez is more explosive offensively, and he's a middle infielder. We have Jones and Chavez on the bench as well. Posada serves as our emergency catcher, well, when Montero comes up, Jorge will be our 4th catcher. He's been a great Yankee during a dynasty run and an integral part of 2009 as well. But he's almost 40 and the tools of ignorance have worn his body down to dust. He cannot run, he doesnt walk like he did, he isnt hitting for power, and his average has been wallowing of late in the .220 range. He cannot play a good 1b, he cannot catch, he cannot do anything. He's now been on the roster for 4 full months, and in 3 of those months, his OPS was at or below .641. There is no way around this, he doesnt deserve to be on the 25 man, especially when a guy like Montero is pushing from below.
Montero has had a really strange season thus far. His April was solid (.833OPS), but the power wasnt there (1HR) and he didnt walk in the entire month. He walked 19 times in May and June and hit 5HR, but his K rate was astronomical (25%), leading to OPS's of .747 and .667. Since July 1, though, the power and patience have returned. His line since July 1 is .296/.373/.527 for an OPS of an even .900. The kid is ready, Posada is dying, and we need a jolt for the stretch run. Montero's bat has been compared to Miguel Cabrera and he could have a similar impact a la 2003 when Cabrera came up and really bolstered the lineup. It's a win-win, IMO. You cut Posada and get it out of the way outright. He may bitch and moan and cry, but he'll be off the team and out of the way. In the meantime, the kid comes up as the emergency catcher but primary DH and you ease him in at the bottom of the order where Posada was hitting. If he hits, great. If he doesnt, you have Jones, Nunez and Chavez who could take his place for the post season. But this kid is a superior talent who, after 3 months of weird month to month transitions has put together a solid 40 day run akin to his career norms and it's time for him to get the chance. If he flops, you can option him without any trouble and you have big leaguers around him who can get the job done. If he doesnt, then you have a young, impact bat in your lineup
