So what player couldn't? Not to mention he can demand all he wants, but that doesn't mean he's going to get it. The possibility for a player demanding a trade is an bad reason to pass on a player. In fact, I think the logic that he's in a multi-year deal means that he's got more leverage would actually be just the opposite. He'd have less leverage as he'd have no recourse. Anyway, I really don't why we should take that into consideration either way. (combined consecutive posts -1992) If a player has signed a multi-year contract, and is traded in the middle of that contract, he has a right to demand a trade from his new team after the season. And the team HAS to trade him by March 15. Not just explore possible trades. If he's not traded, he becomes a free agent. Again, that's how he ended up with the White Sox. He was in the middle of a contract when the Yankees traded him the the D-Backs as part of the Randy Johnson deal before the 2005 season. After the 2005 season, he demanded a trade. The D-Backs traded him to the White Sox. There's some lesser restriction (the player has to have 5 years of service and some others), but the bottom line is if we trade for Vazquez this season, we could be forced to trade him after the season is over.
