According to a news on Boston Globe, Yankees have been aggressive in calling team to find out who may be available. For example, they said Yankees called Astros to find out the availability of Roy Oswalt and Lance Berkman.
Man, I doubt this news is true. Think about it. Brian Cashman is going to have GM Meeting that starts on Monday. He can find out anything he wants to know on GM meeting. Why wast time and energy to call other teams? This doesn't make any sense at all.
