Hopefully for the Yankees and Nady's sake this isn't serious. Couldn't have come at a worse time for Nady with Swisher off to such a red hot start. Nady is a free agent after this year.Yankees right fielder Xavier Nady will undergo a magnetic resonance imaging exam on Wednesday morning after leaving the Yankees' 7-2 victory against the Rays on Tuesday night when he felt a sharp pain in his surgically repaired right elbow. "I'm hoping it's just one of those flare-ups," said Nady, who felt the pain after throwing the ball back to the infield on Carlos Pena's seventh-inning single. He felt the pain once again on the next play, when he threw the ball back to the infield after catching Pat Burrell's sacrifice fly. Melky Cabrera came on as a defensive replacement at the end of the seventh. "Just the way I felt tonight, I had to say something," said Nady, who underwent Tommy John surgery in Sept. 2001
