3-game lead; no titles yet

DENVER (AP) - Pinch-hitter Chris Iannetta hit a two-run homer off David Weathers in the 11th inning to give the Colorado Rockies a 7-5 victory over the Milwaukee Brewers on Tuesday night.

Iannetta sent a 3-2 fastball into the Rockies' bullpen in right-center with one out for his 16th homer and first career game-ending drive.

The Rockies widened their NL wild card lead to three games over Atlanta with five games remaining.

The crowd of 39,087, pretty big for a Tuesday night in downtown Denver, let loose a loud cheer when the Braves' 5-4 loss to the Marlins was announced on the scoreboard in the middle of the sixth.

Padres 3, Dodgers 1

At San Diego, Tony Gwynn Jr. homered, Kevin Kouzmanoff singled in the go-ahead run and the Dodgers again failed to clinch their second straight NL West title.

The Dodgers have lost three straight since securing a playoff spot on Saturday night.

Heath Bell got his NL-best 41st save and Ryan Webb (2-0) earned the win.

Chad Billingsley (12-11) lost for the fifth time in his last seven starts.

Phillies 7, Astros 4

At Philadelphia, Pedro Feliz hit a grand slam and the Phillies moved closer to their third straight NL East title. The defending World Series champions' magic number for winning the division was reduced to one when Atlanta lost to Florida.

J.A. Happ (12-4) allowed four runs -- three earned -- and nine hits in 5 2-3 innings, striking out six. Jayson Werth hit a two-run homer and Philadelphia's injury-plagued bullpen tossed 3 1-3 scoreless innings.

Marlins 5, Braves 4

At Atlanta, Jorge Cantu hit a tiebreaking RBI single in the seventh and Florida snapped the Braves' seven-game winning streak but was eliminated from playoff contention when the Rockies won later Tuesday night.

Cameron Maybin's two-run homer gave the Marlins a 4-1 lead in the fifth inning before Matt Diaz hit a tying three-run drive in the sixth for the Braves.

Renyel Pinto (4-1) pitched 1 1-3 scoreless innings to earn his first win since June 30. Leo Nunez worked the ninth for his 25th save.

Giants 8, Diamondbacks 4

At San Francisco, Bengie Molina homered twice and Pablo Sandoval had four hits to keep the Giants' slim wild-card hopes alive.

The Giants trail wild card-leading Colorado by five with five games left. Jonathan Sanchez (8-12) allowed three runs and five hits in 5 1-3 innings.

Reds 7, Cardinals 2

At Cincinnati, Jay Bruce homered twice and had a career-high five RBIs to help send the NL Central-champion Cardinals to their fourth loss in five games.

Homer Bailey (7-5) pitched seven solid innings and Joey Votto also connected for the Reds, who have won seven of eight.

Joel Pineiro (15-12) allowed seven runs and eight hits in six innings to fall to 1-3 in his last four starts.

Nationals 4, Mets 3

At Washington, Justin Maxwell scored the tiebreaking run in the eighth inning thanks to two wild throws by New York.

Tyler Clippard (3-2) pitched two scoreless innings for the win and Mike MacDougal picked up his 18th save with a scoreless ninth thanks to Elijah Dukes' spectacular catch to end the game.

Cubs 6, Pirates 0

At Chicago, Ryan Dempster pitched a five-hitter for his third career shutout to lead the Cubs, who have won seven of nine but were eliminated from the playoff race when Colorado beat Milwaukee.

Dempster (11-8) struck out six and walked two in his first shutout since July 3, 2001.
