Bedard earns first win, Pirates beat Braves, 4-2
Presley had two hits to extend his career-best hitting streak to 12 games. He scored two runs and drove in a run with a double. Pedro Alvarez also had a run-scoring double.
Bedard (1-4) gave up only one run in five innings. The left-hander struck out nine while giving up five hits and two walks. He has not allowed more than two earned runs in any of his five starts.
Jason Grilli struck out the side in the eighth and Joel Hanrahan added two strikeouts in a perfect ninth for his fourth save. The game ended when right fielder Jose Tabata made a leaping catch at the wall of pinch-hitter Eric Hinske's drive.
The Pirates scored a total of two runs with Bedard on the mound in his first four starts -- the majors' lowest run support for a pitcher. They topped that by taking a 3-0 lead in the first two innings against Randall Delgado (2-2).
Presley led off the game with a single and scored from third on Garrett Jones' flyball to center field. Presley's second-inning double into the left field corner drove in Rod Barajas, who singled. Tabata's single to right drove in Presley for a 3-0 lead.
Martin Prado doubled in the third inning and scored on Dan Uggla's two-out single for the Braves' first run.
The Pirates knocked Delgado out of the game in the fifth with back-to-back doubles by Neil Walker and Alvarez, pushing the lead to 4-1.
Bedard struck out Freddie Freeman and Uggla with runners on second and third to end the fifth.
The Braves scored a run off Chris Resop in the sixth when Jason Heyward doubled, stole third and scored on Juan Francisco's grounder to first. Heyward has eight steals.
After Tyler Pastornicky singled and advanced to third when the ball skipped past Tabata for an error, pinch-hitter Chipper Jones ended the inning with a grounder to second base.
Delgado gave up four runs on eight hits and three walks in 4 1-3 innings, leaving his ERA at 6.30. He has allowed a combined nine runs in his last two starts, both losses, after winning his first two starts.
Braves catcher Brian McCann, who left Friday night's game with a strained muscle in his right side, did not play. He said he felt better Saturday and hopes to play on Monday. Outfielder Matt Diaz was to be the emergency backup catcher to fill-in starter David Ross.
