Houston ? Randy Johnson stopped another Arizona losing streak.

Johnson held Houston hitless into the sixth inning and didn’t allow a run in eight innings, leading the Diamondbacks to a 9-1 victory over the Astros on Wednesday night.

Arizona pitcher Randy Johnson whips a pitch toward home plate. The Diamondbacks defeated the Astros, 9-1, Wednesday in Houston.

Johnson (12-2) helped Arizona snap a three-game skid and improved to 9-0 this when pitching after a Diamondbacks loss.

“He definitely is a streak stopper,” Arizona’s Mark Grace said. “I was kind of hoping he would get the no-no, but he was still dominant. I remember when I played against him, you knew if you won the first two games and he was pitching the third you had better believe you were going to lose.”

Johnson didn’t give up a hit until Gregg Zaun lined a single to center with one out in the sixth inning.

“I got a couple of pitches to hit early in the count, but the hit was luck,” Zaun said.

Johnson allowed three hits and struck out eight before Todd Stottlemyre pitched the ninth to finish the five-hitter.

“I didn’t think about the losing streak. I had a job to do and I did the best I could,” Johnson said. “You are always going to have a few losing streaks. If I happen to be in the position to end it, so be it.”

Steve Finley and Mark Grace drove in two runs apiece for the Diamondbacks, who had lost three straight games.

Wade Miller (3-3) gave up six runs five earned and seven hits in five innings to snap a three-game winning streak. He struck out five and walked two.

Giants 6, Padres 5

San Francisco Shawon Dunston’s run-scoring infield single capped a three-run ninth inning against San Diego closer Trevor Hoffman on J.T. Snow’s RBI single in the 12th.

Benito Santiago and Snow singled and Barry Bond walked. Pinch-hitter Marvin Benard drove in two runs a with a double and took third as Bonds was thrown out at the plate before Dunston’s game-tying hit. Jay Witasick (1-0) pitched a perfect 12th for the victory.

Reds 8, Cubs 6

Chicago Sean Casey knocked Cubs starter Jason Bere out with a line drive off the pitcher’s right knee and also hit one of four Cincinnati home runs.

Todd Walker, Adam Dunn and Juan Encarnacion also homered for the Reds. Jimmy Haynes (8-6) worked six innings, and Danny Graves got his 23rd save.

Pirates 7, Expos 4

Pittsburgh Brian Giles homered and drove in three runs to help Kip Wells win for the first time in five starts.

Wells (9-4) hadn’t won since he beat the Chicago Cubs 5-0.

Montreal tied the score at 3 in the fifth on Jose Vidro’s two-run homer, his eighth. But the Pirates beat Javier Vazquez, and Mike Williams pitched the ninth for his 21st save.

Braves 6, Mets 3

New York Gary Sheffield’s tiebreaking grand slam in the eighth inning overcame two homers by the Mets’ Mo Vaughn. David Weathers (2-3) took the loss after walked pinch-hitter Keith Lockhart leading off the eighth. Darren Bragg reached when first baseman Vaughn bobbled his sacrifice bunt for an error, and both runners moved up on a sacrifice by Rafael Furcal.

Marlins 6, Phillies 2

Miami Pitcher Michael Tejera homered a day too late and Cliff Floyd and Derrek Lee hit consecutive home runs for Florida.

Tejera hit his first career homer, a solo shot in the second inning. On Tuesday night, after the Marlins ran out of position players, Tejera was sent up as a pinch-hitter and struck out to end Florida’s 7-6 loss in 11 innings to the Phillies.

Cardinals 5, Brewers 2

St. Louis With the late Darryl Kile’s 5-year-old son Kannon throwing out the first pitch, the St. Louis Cardinals won a game.

Woody Williams and Mike Matheny, who spoke at a memorial service for Kile earlier in the day, played pivotal roles as the Cardinals ended a four-game losing streak.

Williams (5-3) allowed two runs in 7 2-3 innings and had an RBI single. Matheny had his first two-RBI game since April 25 as the Cardinals beat Jamey Wright (1-6).

Dodgers 5, Rockies 3

Los Angeles Hideo Nomo won his sixth straight decision and doubled home the go-ahead run, and Shawn Green hit his 21st homer in 33 games as Los Angeles beat Colorado.

The Rockies were held to four hits, a day after Los Angeles lefty Odalis Perez pitched a one-hit shutout against them.

Nomo (8-5), who pitched his first no-hitter while with the Dodgers in 1996, allowed just two hits over seven innings. Eric Gagne got three outs for his major league-leading 28th save in 29 chances.
