VIERA, Fla. -- One day after pitching for Mexico in its final game of the World Baseball Classic, Nationals right-hander Luis Ayala learned Friday that he needs Tommy John surgery and will be out for the entire 2006 season. Ayala will have surgery in two weeks.
In the top of the ninth inning between Mexico and the United States on Thursday, Ayala walked Yankees third baseman Alex Rodriguez. A few minutes later, the trainer for Mexico came out to check on Ayala, who was taken out of the game.
On Friday morning, Ayala went to see Dr. Lewis Yocum, who discovered that the 28-year-old has an ulnar-collateral ligament sprain in his right elbow. Yocum removed a bone spur from Ayala's right elbow last offseason.
