Atlanta ? Russ Ortiz gave the Atlanta Braves another reason to celebrate.

One day after the Braves clinched their 12th straight division title on an off day, Ortiz won his 20th game in style, pitching a three-hitter and driving in the only run as Atlanta defeated the Florida Marlins, 1-0, Friday night.

The Braves already were planning a postgame celebration in honor of their 1-day-old NL East championship, but Ortiz’s performance made the champagne taste even sweeter.

“That has to be the best game I’ve ever thrown overall,” Ortiz said, savoring the first 20-win season of his career.

How’s this for an overall performance? Ortiz provided all the offense with a two-out, RBI single in the second. He also made the game’s signature defensive play, snaring a liner up the middle by Juan Encarnacion.

“What better way to win your 20th than to drive in the winning run yourself?” Florida manager Jack McKeon said. “That may have been the best-pitched game against us this year.”

Cubs 10-6, Pirates 9-10

Pittsburgh — Craig Wilson and Rob Mackowiak drove in two runs each, and Pittsburgh beat Chicago, 10-6, in the second game of a doubleheader, dropping the Cubs 1 1/2 games out of the NL Central lead. The Cubs overcame Pirates rookie Jason Bay’s eight RBIs to win the opener, 10-9, but still lost a half-game in the standings during a long evening necessitated by a May 20 rainout. Matt Stairs hit a solo homer, and Carlos Rivera had an RBI double.

D’backs 3, Brewers 2

Milwaukee — Randy Johnson hit his first major-league home run, and Steve Finley’s solo shot broke a ninth-inning tie as Arizona defeated Milwaukee. Matt Kata also homered for the Diamondbacks. Eddie Perez went deep for Milwaukee. Johnson had gone 436 at-bats without a homer until lining a 385-foot solo shot to left-center off Doug Davis in the third inning.

Astros 8, Cardinals 1

St. Louis — Roy Oswalt dominated for seven innings, and Houston got home runs from Jeff Bagwell and Richard Hidalgo. Houston has won six of seven and is a season-best 15 games above .500.

Philadelphia — Mike Lieberthal homered twice and drove in four runs as Philadelphia beat Cincinnati and reclaimed the NL wild-card lead. The Phillies moved a half-game ahead of Florida. Randy Wolf (16-9) won his fourth straight decision, giving up two runs and four hits in six shaky innings. He worked around four walks, striking out eight.

Expos 7, Mets 1
