Detroit Tigers closer Troy Percival hoped that a long layoff would help his aching right arm. Unfortunately, his injury proved to be too much to overcome. Percival, who is in 10th place on the all-time saves list with 324, experienced pain while throwing a simulated game at the Tigers' spring training facility Sunday and admitted that his major league career is likely over. The once hard-throwing righthander tore a muscle in his elbow last season, his first with Detroit. He was limited to just 26 games and did not pitch after July 9. Although the muscle is still torn, Percival strengthened the muscles around it in the offseason and hoped to pitch again. "I always wait for something miraculous to happen," Percival said. "I probably don't think its going to happen, but I'll keep doing what they ask to do."
