If the Los Angeles Dodgers end up winning the National League West, this weekend's series against Arizona might be the catalyst that got them there.

The Dodgers took two of three from Arizona to pull even with the Diamondbacks in the NL West. Los Angeles rallied for five runs in the ninth inning off Diamondbacks closer Brandon Lyon to win 6-5 on Sunday.

"That was a huge win," said Dodgers manager Joe Torre. "It was nice to be able to steal that one."

The plucky St. Louis Cardinals staged their own ninth-inning rally to beat San Diego 9-5 on Aaron Miles' game-winning grand slam. It was the first game-ending hit of his career and helped the Cardinals recover from another blown save by Jason Isringhausen. St. Louis swept a four-game set from San Diego.

Marlins 3, Phillies 2

At Miami, Jorge Cantu hit a bases-loaded single off the scoreboard with none out in the 11th inning, and the Florida Marlins tightened the NL East race.

Cubs 9, Astros 0

At Houston, Ryan Dempster struck out seven in eight shutout innings to earn his first road win in two years, and Chicago snapped a three-game losing streak.

Mets 7, Reds 5

At Cincinnati, third baseman Edwin Encarnacion hit one of Cincinnati's three homers off Mike Pelfrey, then made a throwing error in the 10th inning that helped New York rally for a victory and a split of their four-game series.

The Mets have won 11 of their last 13 games, salvaging their season one month after they fired manager Willie Randolph.

Brewers 7, Giants 4

Ryan Braun hit a three-run homer and drove in a career-high five runs, pitcher Manny Parra had an RBI single en route to winning his eighth straight decision and Milwaukee completed a season sweep of San Francisco.

Nationals 15, Braves 6

At Atlanta, former Braves outfielder Willie Harris drove in five runs and reached base five times, Jesus Flores had five hits and Austin Kearns hit a two-run homer as Washington routed Atlanta.
