MONTREAL - Rookie Claudio Vargas allowed three hits in eight innings and Edwards Guzman hit his first home run in nearly two years, leading the Montreal Expos to a 3-0 win over the Pittsburgh Pirates on Monday night.

Making his 11th start since he was recalled from Triple-A Edmonton on April 24, Vargas (4-3) allowed singles to Aramis Ramirez and pitcher Jeff Suppan, and a double to Matt Stairs.

Guzman, whose contract was purchased from Edmonton on June 7, connected off Suppan (5-7) with one out in the third for his first homer since Aug. 9, 2001, with San Francisco at Cincinnati.

Rocky Biddle pitched the ninth for his 20th save in 23 chances.

Montreal won for just the third time in its last 11 games. The Expos have seven shutouts this season after recording only three last year.

Pittsburgh, which lost its second game in a row, had won six of eight.

Vargas, acquired from Florida along with Cliff Floyd last July 11, was perfect in the first, fourth and fifth. He walked one, hit two batters with pitches and struck out two, matching his longest outing.

Montreal opened the scoring in the second. Ron Calloway drew a two-out walk and scored on Brian Schneider's RBI double.

After Guzman's homer made it 2-0, Orlando Cabrera tripled and scored on Jose Vidro's single to put the Expos up by three.

Suppan allowed eight hits and three runs in seven innings.

Giants 3, Dodgers 2, 11 innings

SAN FRANCISCO - Barry Bonds stole the 500th base of his career and scored on Benito Santiago's single in the 11th inning as San Francisco beat Los Angeles.

Bonds led off by drawing a walk from Los Angeles closer Eric Gagne (1-2), then became the first player ever with 500 stolen bases and 500 homers when he took second without a throw.

After a brief delay while Bonds uprooted the base and waved to the crowd, Andres Galarraga struck out. Santiago then singled to left, and Bonds sprinted home.

Felix Rodriguez (3-0) pitched one scoreless inning for the win.

The Dodgers trailed 2-0 before scraping out two unearned runs in the ninth against Giants closer Tim Worrell.

With runners on first and second and one out, Larry Barnes hit a textbook double-play grounder. But second baseman Ray Durham threw wide of second base, allowing pinch-runner Jason Romano to score and sending Adrian Beltre to third.

Cesar Izturis then grounded into the first-base hole, allowing Beltre to score. Paul Lo Duca nearly extended the rally with a two-out drive down the right-field line, but Jose Cruz Jr. made a spectacular diving catch.

D'Backs 7, Astros 6

PHOENIX - Luis Gonzalez broke an eighth-inning tie with a two-run triple, Quinton McCracken added a bases-loaded triple, and the Arizona Diamondbacks held off the Houston Astros in the ninth for a 7-6 win Monday night, their season-high sixth straight victory.

After the Astros rallied for four runs in the ninth to cut it to 7-6, Brady Raggio retired Richard Hidalgo on a grounder with two on for his first career save.

Ricky Bottalico (1-0), recalled from the minors earlier in the day, pitched a scoreless eighth for his first big league victory since Sept. 18, 2001.

Gonzalez followed a single by Steve Finley and a walk to Alex Cintron with his first triple of the season, a shot into the right-field corner that Hidalgo did not play well as both runners scored to snap a 2-2 tie.

Arizona's winning rally came against Brad Lidge (4-1). Before Lidge left he walked Lyle Overbay and Chad Moeller, then McCracken lined his first triple of the year into the left-field corner against Pete Munro, clearing the bases and giving the Diamondbacks a 7-2 lead.

Houston scored four runs in the ninth on an RBI single by Craig Biggio, a two-run single by Jeff Bagwell and a run-scoring wild pitch by Mike Myers. After Myers plunked pinch-hitter Morgan Ensberg with a pitch, Raggio came in and retired Hidalgo on a grounder to third.

Rockies 5, Padres 1

SAN DIEGO - Colorado's Shawn Chacon became the NL's first 11-game winner with his second win in five days against the Padres.

Chacon (11-3) held San Diego to four hits in seven innings to win his third straight start and seventh of eight. He tied his season high with eight strikeouts and walked one.

Chacon beat the Padres 5-3 on Wednesday night at Coors Field. San Diego's Kevin Jarvis (0-2) lost both games.

Jarvis fell behind 2-0 after facing six batters. Juan Uribe hit a leadoff double and Todd Helton was intentionally walked with one out. That backfired when Jarvis walked Preston Wilson to load the bases. Chris Stynes hit a two-run single to left with two outs.

McGriff on DL for first time in career

SAN FRANCISCO - Los Angeles Dodgers first baseman Fred McGriff went on the disabled list Monday for the first time in his 18 major league seasons.

McGriff, who has 488 career homers, had missed eight straight games with a nagging injury to his right groin. Faced with losing McGriff for the entire week if they waited any longer, the Dodgers put him on the DL retroactive to June 14, making him eligible to return on Sunday.

The move was disconcerting to McGriff, who's been a model of consistency and durability during his career - but he agreed with it.

"I figure I'm hurting the team if I get on base and I can't score," McGriff said. "I pride myself on going out there every day and staying away from injuries, but this time, it got me. I guess I didn't do something right in the offseason."

The Dodgers recalled Larry Barnes from Triple-A Las Vegas to replace McGriff on the roster. Barnes was expected to arrive Monday night during the opener of the Dodgers' three-game series against the San Francisco Giants.

McGriff has played for six teams during a career that began in 1986 with the Toronto Blue Jays. In his first season as Los Angeles' starting first baseman, he has a team-leading 10 homers and 35 RBI, good for second on the team. But he hasn't felt completely whole for weeks.

"I've been playing with it for a while," McGriff said of the discomfort in his upper right leg. "It's been tight for a while. I've just got to rest it for a few days."

McGriff hasn't played since aggravating the injury during a road trip to Cleveland, but the problem has been difficult to pinpoint, and hasn't improved recently. It was a new experience for McGriff, who has never missed more than a few games with similar leg injuries during his career.

"It's improving, but he's obviously still bothered by it," Dodgers manager Jim Tracy said.
