I agree that it's really unlikely, but I also think if anyone were to decide to leave that kind of money on the table it would be Z. It's possible that he's run out of people to blame for his dwindling success and may just not enjoy going out there anymore because he's not up to his own standard of play. He very likely has too much pride to phone it in and count his money next year, and the trade that he'd be likely to force could potentially offend him as well. He's also just stubborn enough to tell his agent and the mlbpa to go [expletive] themselves. Allowing for ALL that, I think there's a 10% chance he retires. Jesus, I just did this up PTI-style. There's no way Zambrano leaves that much money on the table. Also, his agent and the player's union would certainly push him to return. Hmm, never really thought of it that way before Yeah, that's why I mentioned the union; they're going to be VERY interested if he's trying to walk away from that kind of money. They're the same reason I don't see Pujols taking the severe hometown discount many seem to assume he'll end up taking. The union simply will not let players leave that much on the table, especially when it establishes a precedent detrimental to other players down the line. In Zambrano's case it's arguably a further hindrance to any talented player with any kind of "emotional" history trying to max out a new contract.
