Pat Burrell hit a two-run homer, Chase Utley had a key two-run single and the Phillies won for the fourth time in five games. They're 14-and-9 since a 4-and-11 start.
J.J. Hardy his league-leading 12th homer and Johnny Estrada also connected, but the Brewers' stellar bullpen blew a four-run lead in the eighth.
Clay Condrey pitched a scoreless eighth and Brett Myers finished for his fourth save in four chances.
Trailing 6-2, the Phillies loaded the bases against relievers Brian Shouse and Derrick Turnbow with no outs in the eighth. Aaron Rowand singled and Shane Victorino doubled to chase Shouse. Turnbow came in and walked Jimmy Rollins. Turnbow's wild pitch forced in one run and Utley's two-run single cut it to 6-5.
After Burrell flied out to right field, Greg Dobbs and Abraham Nunez hit consecutive singles to right field to load the bases again. Carlos Ruiz followed with a grounder to first baseman Fielder, but Utley beat the throw home to score the tying run.
Helms then singled off the right-field wall to make it 7-6 and Rowand's sacrifice fly drove in an insurance run.
Turnbow gave up four runs and four hits while recording only two outs.
