Wolf (15-9) gave up five runs and eight hits, although most of them came after being staked to a 10-1 lead through three innings. Wolf had a hand in the Phillies offense, scoring twice and driving in a run as he raised his batting average to .194.
Wolf walked one and struck out six before being relieved by Rheal Cormier, who gave up two runs while getting five outs. Former Pirate Mike Williams worked the ninth for his 28th save but just his third with the Phillies.
Every Phillies starter had at least one hit in the first three innings. Philadelphia scored two runs in the first, six in the second and two in the third. Among the 14 hits were just two doubles - one by Wolf - and no homeruns.
Bobby Abreu drove in the Phillies first run of the game with an RBI single in the first inning. Later in the inning, Ricky Ledee hit into a double play that allowed another run to score and gave the Phillies a 2-0 lead.
The Phillies broke the game open with six runs in the second inning. Nick Punto led off with a single and went to second on an error by Reggie Sanders. Wolf followed with an RBI double and then scored on an RBI single by Jimmy Rollins for the first two runs of the inning. Jim Thome followed with a two run double to make it 6-0 and Ledee chipped in with an RBI single to score Thome. Singles by Todd Pratt and Chase Utley plated another run to cap the scoring as the Phillies took an 8-0 lead.
Thome helped to drive in two more runs in the third inning. Wolf, Byrd and Abreu all singled to load the bases and Thome hit a sharp grounder and Jeff Reboulet couldn't make a play as Wolf and Byrd crossed the plate.
While the Phillies stuck to hitting mainly singles, the Pirates used the long ball. Carlos Rivera hit his second homerun of the season off of Wolf in the seventh to make it a 10-5 game and send Wolf to the clubhouse. Cormier gave up solo homeruns to Craig Wilson and J.J. Davis in the eighth as the Pirates moved to within three runs.
The win moved the Phillies within 1 1/2 games of the Florida Marlins in the race for the National League wild card berth. The Marlins allowed the Braves to come from behind for an 8-4 win in their game on Sunday. The Phillies and Marlins still play six games against each other with the first three starting Tuesday in Philadelphia. The pitching matchup has Vicente Padilla (13-10, 3.70) going against Carl Pavano (11-11, 3.96) in the series opener.
