The Marlins went 7-3 on their homestand, with six wins by one run.
The Braves loaded the bases four times, including in the 11th, and those situations produced only one run. They stranded 11 runners.
Florida’s Hanley Ramirez singled off Jesse Chavez (2-2) to start the bottom of the 11th, and he took third on a single by Dan Uggla . After Cody Ross was intentionally walked to load the bases, Helms hit an 0-1 pitch through the left side of the infield and was mobbed after rounding first base.
Jorge Sosa (2-2), who came up from Triple-A this week, pitched two scoreless innings.
Padres 6 Pirates 3: At Pittsburgh, Adrian Gonzalez and Chris Denorfia homered, Wade LeBlanc won for the first time in six weeks and the first- place San Diego Padres finished off its only series sweep in Pittsburgh since 1998.
The Padres have won all 10 series in Pittsburgh since PNC Park opened in 2001, but hadn’t swept one there before outscoring the Pirates 20-8 in the three weekend games.
Gonzalez’s two-run homer, his 21st, highlighted a five-run third inning against Pirates rookie Brad Lincoln (1-4), who was sent back to Triple-A after the game.
Giants 3 Diamondbacks 2, 10 innings: At Phoenix, Buster Posey had four hits to extend his hitting streak to 18 games and Travis Ishikawa hit a run-scoring single in the 10th inning, helping the San Francisco Giants beat the Diamondbacks 3-2 on Sunday to complete their first four-game sweep in Arizona in nine years.
The Diamondbacks, who traded three-time All-Star right-hander Dan Haren during the game to the Los Angeles Angels for three pitchers and a player to be named, had runners on the corners in the ninth, but Sergio Romo (3-3) struck out Cole Gillespie and Chris Young.
Posey started the winning rally with a double, setting up Ishikawa’s single off Esmerling Vasquez (1-3) that easily scored pinch-runner Eli Whiteside and gave the Giants their first four-game sweep in Arizona since July 26-29, 2001.
Phillies 4 Rockies 3: At Philadelphia, Jimmy Rollins singled home the tying run in the seventh inning then put the Phillies ahead for good by scoring on a wild pitch.
After a long rain delay, pinch-hitter Wilson Valdez started the seventh inning with a double to right. Rollins followed with an RBI single off Joe Beimel (1-1). Rollins advanced to second on an error by left fielder Ryan Spilborghs .
Two outs later, reliever Rafael Betancourt threw a pitch that bounced away from catcher Miguel Olivo . Rollins, who had stolen third, scored without a play.
Astros 4 Reds 0: At Houston, Wandy Rodriguez allowed one hit in seven innings, Hunter Pence and Chris Johnson homered for the Astros.
Michael Bourn drove in two runs with a double in Houston’s three-run seventh to help the Astros avoid a three-game sweep against Cincinnati.
Rodriguez (8-11) struck out seven for his fifth win in his last six starts. Brandon Lyon gave up one hit in the eighth and Matt Lindstrom did the same in the ninth to complete the shutout.
Brewers 8 Nationals 3: At Milwaukee, Casey McGehee and Rickie Weeks homered and the Milwaukee Brewers scored five unearned runs off starter Ross Detwiler in beating Washington to complete a three-game sweep.
Washington, who made two costly errors, leads the majors with 80 errors.
Milwaukee took a 2-0 lead on Jonathan Lucroy’s RBI single and a wild pitch by Detwiler (0-1) after third baseman Willie Harris misplayed a grounder.
In the fourth, shortstop Ian Desmond bobbled Dave Bush’s two-out roller and threw it away, allowing Lucroy to score.
Dodgers 1 Mets 0: At Los Angeles, Clayton Kershaw scattered seven hits over eight innings in his first start since appealing a five-game suspension and Russell Martin hit a late RBI double in the Dodgers’ victory over the punchless Mets.
Former catcher Kenley Jansen got his first major league save, handing New York its fourth shutout loss on a 2-9 road trip to San Francisco, Arizona and Los Angeles. Mets starter R.A. Dickey came out in the sixth with an injured left leg.
Kershaw (10-5) stranded six runners, struck out three and issued an intentional walk.
Cardinals 4 Cubs 3, 11 innings: At Chicago, Felipe Lopez hit a tiebreaking solo homer in the inning to help the Cardinals beat the Cubs and avoid a weekend sweep.
Lopez drove a 3-2 pitch from Brian Schlitter (0-1) over the right-field wall for his sixth homer of the season to put the Cardinals back in the NL Central lead, a half game ahead of Cincinnati.
The big hit came one day after Lopez was scratched from the starting lineup for reportedly arriving late to the ballpark. It also made a winner of closer Ryan Franklin (5-1), who pitched two innings.
