T.J. Beam (1-1) pitched two scoreless innings of relief for Pittsburgh, and Craig Hansen tossed the 12th for his third save of the season and first since he was traded from the Boston Red Sox in the three-team Manny Ramirez deal on July 31.
Hansen got some help from Brandon Moss, who made a diving grab in left-center on Chase Utley's fly ball with runners on first and second and one out. Moss threw to Freddy Sanchez covering second to try to double up Jimmy Rollins, but he made it back safely. Sanchez then spun and threw to first and doubled up Shane Victorino to end the game.
The Phillies were shut out for the second straight day and watched their NL East lead shrink to one game over the New York Mets, who beat the Florida Marlins 3-0. Philadelphia has gone 23 innings without scoring a run.
Though neither starting pitcher factored in the decision, Philadelphia's Joe Blanton and Pittsburgh's Paul Maholm controlled the game for the first seven innings.
Acquired by the Phillies last month in a trade with Oakland, Blanton allowed just one hit - a leadoff single by Doug Mientkiewicz in the fourth. Blanton walked two, tied a season-high with seven strikeouts and didn't allow a Pirates runner past first base.
Maholm scattered five hits, walked three, and struck out a career-high 10, including five straight between the fifth and seventh innings.
Pat Burrell nearly broke the deadlock in the eighth, but his two-out fly ball to left was caught at the fence by Moss.
