Chicago ? Steve Finley is enjoying his worst-to-first job change while providing an extra offensive push for the streaking Los Angeles Dodgers.

“We’re winning. It’s great,” Finley said Friday after driving in three runs, and the Dodgers scored six times in the ninth to beat the Chicago Cubs 8-1.

“We have the momentum. Everybody is pushing in one direction here. Everybody knows to just go out and get the job done, whatever it takes. You win a lot of games that way.”

Finley, 13-for-26 in 10 games since being traded from last-place Arizona to the first-place Dodgers, hit an RBI single to break a 1-1 tie in the sixth.

He added a two-run single in the ninth when the Dodgers took advantage of Chicago’s wilting bullpen and the Cubs’ wobbly defense.

“We squeaked a hit through whenever we needed it, and we broke it open there in the ninth,” Finley said.

The NL West leaders won for the 28th time in 37 games.

Pinch-hitter Robin Ventura and Milton Bradley hit RBI singles off Kyle Farnsworth in the ninth, Shawn Green added another run-scoring single off Jon Leicester, and Chicago’s Moises Alou and Michael Barrett made errors.

Alou missed Alex Cora’s fly for a two-base error, and Barrett dropped Farnsworth’s throw on a bases-loaded comebacker.

“The ninth inning, that was a nightmare with a couple of errors,” Cubs manager Dusty Baker said after his team’s fifth loss in seven games.

Odalis Perez (6-4) gave up six hits and a run in 62/3 innings. In his first start since winning his 300th game last Saturday in San Francisco, Greg Maddux (11-8) gave up eight hits and two runs in 6 1/3.

Giants 16, Phillies 6

Philadelphia — J.T. Snow homered three times, scored a career-best five runs and knocked in four, and Barry Bonds hit career homer No. 689 for San Francisco. It was Snow’s first career three-homer game. He also walked twice.

Bonds went 2-for-2, scored three runs, had two RBIs and was walked three times, twice intentionally. The two intentional walks gave him a major-league high 86 on the season. It helped the Giants break their two-year old major-league record of intentional walks in a season with 104.

Milwaukee — Wes Obermueller gave up two hits in seven shutout innings in an emergency start for Milwaukee, earning his first win in almost 11 weeks. Russell Branyan and Lyle Overbay each hit two-run homers for the Brewers, who won for just the third time in 10 games.

Obermueller (4-6) took the place of Chris Capuano, who was scratched just before the game with a sore left forearm.
