it still makes Prado difficult to trade. the team trading for him would have to work out some sort of an extension before they would be willing to give up anything of value for him. not saying its impossible, but AZ seems like they wouldnt risk losing upton for just 4-5 months of Prado and Delgado. Towers isnt a genius, but hes not a complete idiot. One has to think that they believe they have a real shot at signing him. Obviously if they are tanking at the deadline then it would have to be considered just like anyone on any team reaching the end of their contract.
