ATLANTA (AP) - Martin Prado hit a tiebreaking homer in the eighth inning and Atlanta beat Milwaukee 2-1 on Thursday night to complete a four-game series sweep.
Prado led off against Kameron Loe (2-3) with his third homer. Prado was Loe's first batter in relief of Shaun Marcum, who pitched seven strong innings.
Milwaukee has a six-game losing streak. Atlanta has won five straight.
Jonny Venters (2-0) worked the eighth and Craig Kimbrel pitched a perfect ninth for his seventh save.
Atlanta's Eric Hinske, making only his third start of the season at first base, homered.
Braves rookie Brandon Beachy yielded an unearned run in six innings. He matched his career high with nine strikeouts while allowing four hits and a walk.
Marcum gave up five hits and a walk. He finished with eight strikeouts.
Phillies 7, Nationals 3
PHILADELPHIA (AP) - Roy Halladay struck out 10 in seven innings and Raul Ibanez and Shane Victorino homered as Philadelphia completed a three-game sweep.
Halladay, the reigning NL Cy Young Award winner, allowed two runs and six hits to win his 10th straight decision against the franchise from Washington and Montreal. Halladay (5-1) has won 13 consecutive starts against the NL East.
John Lannan (2-4) allowed seven hits and six runs in two-plus innings to fall to 0-10 against the Phillies.
The NL East-leading Phillies have won 11 of 14 and are tied with Cleveland for the best record in the majors at 21-9.
The Nationals hadn't been swept this season.
Cardinals 6, Marlins 3
ST. LOUIS (AP) - Lance Berkman homered and drove in four runs and Matt Holliday had two RBIs for St. Louis.
Albert Pujols singled three times against Josh Johnson (3-1), the NL pitcher of the month who had an 0.88 ERA in April. He allowed only 18 hits in 41 innings last month, but the Cardinals battered him for eight hits in 25 at-bats.
Holliday fought off an inside pitch for the tying hit with one out in the eighth, chasing Johnson after 114 pitches, and Berkman greeted Mike Dunn with a three-run homer.
Jason Motte (1-0) had a strikeout and a walk in the eighth and Eduardo Sanchez finished for his third save in three chances.
Reds 10, Astros 4
CINCINNATI (AP) - Homer Bailey returned from the disabled list with six strong innings, and Ryan Hanigan drove in three runs with a three-hit game for Cincinnati.
Bailey (1-0) developed a shoulder problem during spring training, forcing him to go on a throwing program. The right-hander gave up four hits and one run in six innings, striking out seven.
The Reds scored six runs in 5 2-3 innings against Brett Myers (1-2), who failed to go six innings for only the second time in 40 career starts with the Astros. Myers also left after 5 2-3 innings of a 9-1 loss in Cincinnati last Sept. 30.
Mets 5, Giants 2
NEW YORK (AP) - Mike Pelfrey pitched into the eighth inning against San Francisco's limited lineup and Carlos Beltran homered as New York averted a series sweep.
San Francisco loaded the bases with one out in the ninth against Francisco Rodriguez, but Miguel Tejada struck out and pinch-hitter Buster Posey grounded out to end the game.
Jose Reyes lined a two-run triple and the Mets took advantage of more wildness from Jonathan Sanchez (2-2) to win for the second time in seven games.
Pelfrey (2-3), expected to be the Mets' ace while injured Johan Santana recovers this year, began the day with a 7.39 ERA. He gave up one earned run and four hits in 7 2-3 innings.
Diamondbacks 3, Rockies 2, 11 innings
PHOENIX (AP) - Gerardo Parra and Chris Young homered off Huston Street in the ninth inning and Arizona won in 11 innings to take two of three from Colorado.
Justin Upton's bloop single to right off Matt Belisle (2-2) brought in the winning run after Young narrowly missed another homer with a double off the overhang in left-center.
Street blew his first save in 12 tries this season after Jason Hammel had thrown seven scoreless innings.
Parra's one-out opposite field homer cut it to 2-1, then Young's two-out shot to left tied it.
Jose Morales drove in two runs off Arizona starter Ian Kennedy with a sacrifice fly and a single. David Hernandez (2-0) got the win with a scoreless 11th.
