The baseball players' union is worried commissioner Bud Selig is trying to hold down the price of Alex Rodriguez's next contract and that teams might be sharing information about their free-agent plans. General managers, in an innovation, each spoke at their annual meeting Tuesday about their offseason goals, and many mentioned what players they were making available. The idea was suggested by this year's co-chairs, Boston's Theo Epstein and Florida's Larry Beinfest, and many GMs said they found it to be useful. "Over the past few days, press reports coming out of the general managers' meetings relating to the sharing of information between clubs as to their plans regarding players potentially raise serious questions concerning the fairness and integrity of the free-agent market," the union said in a statement Thursday night after the four-day session ended. "Such questions are amplified by reports stating that the commissioner is attempting to influence the market for at least one player." A person familiar with the union's statement said the player in question was Rodriguez. The person spoke on the condition of anonymity because the statement didn't refer to A-Rod by name.
