If the Nats GM did try and meet with Soriano before he made the trade, and if that discussion was to discuss a move to the outfield from 2B, and then made the trade when TX refused to allow the meeting, Soriano may have an argument that playing 2B was an "implied" term of the contract that was recognized by both sides. If the GM did not think it was part of the "deal" so to speak, then he will have to explain why he wanted to discuss this with Soriano. By making the trade knowing Soriano's position and without clarifying things, Bowden opened himself up for this. Like I said before, "good baseball men."
Willie, I think you made a valid point with the "implied" term in the contract. Can't buy in to the rest though.
