NL roundup: Dodgers complete a 3-game sweep of the Padres

SAN DIEGO — Russell Martin's RBI single was one of only two hits for the Los Angeles Dodgers, who beat the first-place San Diego Padres 1-0 on Sunday for a three-game sweep and their season-high seventh straight victory.

The Dodgers, playing again without Andre Ethier, won for the 12th time in 15 games.

Chad Billingsley (4-2) shut down the Padres over 7 1-3 innings, allowing just four singles, striking out six and walking one. Jonathan Broxton pitched a perfect ninth for his third save.

Padres starter Wade LeBlanc (2-1) allowed only two baserunners the first five innings, both on walks, and one of them was erased in a double play.

GIANTS 4, ASTROS 3: At San Francisco, Barry Zito earned his sixth win of the season, Aaron Rowand hit a go-ahead home run in the sixth inning and the Giants finished a three-game sweep. Andres Torres homered, doubled and scored twice for the Giants, who have won eight straight games against the Astros dating to 2009. Zito (6-1) rebounded nicely from his only loss of the season, scattering six hits over seven innings while striking out four with one walk. Brian Wilson pitched around two hits to earn his ninth save. Carlos Lee homered for Houston, which has lost three straight following a season-high four-game winning streak. Brett Myers (2-3) went eight innings for the loss.

ROCKIES 2, NATIONALS 1: At Denver, Brad Hawpe hit a go-ahead sacrifice fly in the eighth, and Colorado won after Jeff Francis threw seven sharp innings in his first start since September 2008. The Rockies scored their first run of the game on Miguel Olivo's sacrifice fly.

Pinch hitter Seth Smith began their winning rally in the eighth by drawing a walk off Tyler Clippard (7-2). Carlos Gonzalez singled, Dexter Fowler bunted and Hawpe hit a deep fly ball. Matt Belisle (1-0) pitched the eighth and Manuel Corpas the ninth for his second save.

REDS 7, CARDINALS 2: At Cincinnati, Scott Rolen homered and drove in three runs, helping the surging Reds move a half game ahead of St. Louis following their seventh win in eight games. The Reds haven't been in first place this deep into a season since June 8, 2006. Rolen hit a two-run homer and a run-scoring single off Brad Penny (3-4), who had never lost at Great American Ball Park. Bronson Arroyo (3-2) pitched his first complete game — a seven-hitter — and added a bases-loaded single.
