Atlanta pitcher Jay Powell, making his comeback from ligament transplant surgery, suffered a nightmarish blow on Friday night when he blew out his arm in the ninth inning while trying to save the Braves' 2-1 win over Pittsburgh. He went into his windup with nobody out and delivered a pitch to home plate, but the ball sailed toward the third-base line while Powell collapsed with devastating pain in his right elbow. The 33-year old righthander was placed on the 15-day disabled list while the team recalled Roman Colon from Triple-A Richmond. X-rays to Powell's elbow showed severe damage. "He was in tremendous pain," Braves manager Bobby Cox said. "He could barely walk the pain in his elbow was so severe." Powell signed a minor league contract with the Braves in January after having reconstructive arm surgery on July 8, 2004. He went 2-0 with a 0.64 ERA in Double-A. He has pitched just 3 1/3 innings with the Braves this season.
