After three different relievers were used to get through the eighth inning unscathed, Jonathan Papelbon closed out a 3-1 win to end Pittsburgh's nine-game winning streak.
Entering the eighth inning with two outs and the bases loaded in a two-run game Tuesday, De Fratus didn't have any wiggle room.
He responded by striking out Jordy Mercer on five pitches to end the threat.
Between De Fratus, Antonio Bastardo and J.C. Ramirez, Phillies hurlers needed 31 pitches to escape the eighth. It set up Papelbon for a 1-2-3 save in his first appearance since last Wednesday.
Jonathan Pettibone earned his first win since May 14, tossing 5.2 innings and limiting the Bucs to one run (on a Garrett Jones homer that chased him in the sixth) and three hits while striking out six and walking three. Jake Diekman recorded the final out of the sixth.
The Phillies broke a scoreless tie in the top half of the frame when Ryan Howard snapped an 0-for-22 slump and knocked in Chase Utley with a one-out single to center. Domonic Brown followed with a sacrifice fly to plate Jimmy Rollins, and Delmon Young scored Howard on a double to make it 3-0.
In the leadoff spot, Michael Young picked up another two hits. Young has been incredible in the top spot this season — he's batting 18 for 43 (.419) in 10 games and has raised his average to .291.
In the field, Utley flashed some leather and Brown showed off his arm. With two men on and two outs in the third, Utley made a diving stop on an Andrew McCutchen ball up the middle to save a run. Pettibone struck out the following batter, Garrett Jones. In the seventh, Brown gunned down Mercer at second base from the left-field wall on a throw that was practically off his back foot.
KK 'good to go'
Kyle Kendrick won't have to miss a turn in the rotation after being hit in the head on a pitch by Stephen Fife of the Dodgers on Sunday.
"He should be good to go," Ruben Amaro said before Tuesday's game, per CSNPhilly.com's Reuben Frank.
Kendrick has tossed 12 quality starts in 17 outings this year. He's scheduled to pitch again Saturday.
