Hamels had retired seven straight batters Thursday until Delmon Young hit a line drive high off the left field wall for a double. Then Danny Valencia hit a two-run double, Luke Hughes hit a solo homer. The home run was the sixth of the spring for the first baseman.
Young hit s three-run home in the fifth off Hamels.
Minnesota right-hander Nick Blackburn stymied the Phillies' lineup. Blackburn allowed six hits while striking out five and walking one in six shutout innings.
