Carl Pavano will undergo elbow ligament transplant "Tommy John" surgery, likely ending his career with the Yankees. General manager Brian Cashman said that all four surgeons who examined Pavano's right elbow recommended the operation, and Pavano's agent confirmed by phone that he will undergo the surgery. "It's extremely -- and put this in quotations and capitalized and italics -- frustrating," Clifton said of Pavano's sentiment. "Carl really had hoped that 2007 would be the year that he could show everybody why the Yankees signed him."
