PITTSBURGH—Despite a series of phone calls to Yankees general manager Brian Cashman made right up to Tuesday's 4 p.m. trade deadline, Pirates GM Dave Littlefield was unable to secure the rights to surefire Hall of Famers Alex Rodriguez and Derek Jeter in exchange for those of rightfielder Xavier Nady. "I don't understand This was a trade that could have benefited both teams," said Littlefield, frustrated by the Yankees' refusal to consider the trade even after Littlefield sweetened the deal by offering shortstop Jack Wilson for pitcher Mariano Rivera. "We would have gained sorely needed offense in the infield, while the Yankees had a chance to get a little younger and pare payroll at the same time. Plus, they could have bolstered their defense, as Xavier plays first base, too." Littlefield also confirmed that that the St. Louis Cardinals had pulled the plug on a potential Shawn Chacon-for-Albert Pujols deal at the last second.
