KISSIMMEE, Fla.— While the Atlanta Braves learned that Kris Medlen is definitely done for the season, Alex Wood pitched five dominant innings against the Houston Astros. Wood struck out six and gave up two hits Monday in the Braves' 4-0 victory, a game shortened to five innings by rain. Medlen was Gulf Breeze to be examined by Dr. James Andrews, who confirmed the right-hander will need the second Tommy John operation of his career.
