Rondell White homered on the game's first pitch and Vladimir Guerrero added a two-run shot as the Montreal Expos beat host Colorado, 8-6, last night to complete a doubleheader sweep of the Rockies.

The Expos won the afternoon game, 14-13, when James Mouton scored on an error by first baseman Todd Helton with two outs in the 10th inning.

Guerrero's 27th homer of the season gave Montreal a 6-2 lead in the fifth inning of the nightcap and extended his hitting streak to 18 games -- three short of the Montreal record held by Delino DeShields.

Brad Fullmer also homered in the second game for the Expos, who finished with six home runs on the day. White, Shane Andrews and Geoff Blum had homers in the first game.

The Rockies, who have lost 17 of 21, also hit six homers in the two games, including two by Vinny Castilla.

White went 6 for 10 with four RBI and scored five runs in the two games.

Guerrero has played in 260 consecutive games, breaking Rusty Staub's club record.

GIANTS 3, METS 2: In San Francisco, Rich Aurilia and Marvin Benard homered to back the pitching of Russ Ortiz as the Giants won at home. Ortiz (13-8) yielded two runs on six hits, struck out five and walked three over seven innings to outduel Masato Yoshii (7-8). Robb Nen closed for his 26th save. The loss dropped the Mets one game behind Atlanta in the Eastern division but New York maintained a one-game lead over Houston in the wild card race.

BREWERS 3, DIAMONDBACKS 1: Hideo Nomo (10-5) held host Arizona to four hits over 6 2/3 innings to help Jim Lefebvre get a win in his first game as Milwaukee's interim manager. It was only the Diamondbacks' fifth loss in their last 22 games.

BRAVES 7, DODGERS 3: Chipper Jones hit two homers and Kevin Millwood (13-7) allowed three hits in eight innings and struck out nine to lead visiting Atlanta. Gerald Williams keyed a four-run fourth inning with a two-run single in extending his hitting streak to 15 games. The victory was the seventh in eight games for the Braves.

MARLINS 4, PADRES 3: Brian Meadows (10-11) held host San Diego to one earned run over 7 1/3 innings and drove in a run to lead Florida to its seventh straight victory. The Padres held a 55-minute pregame ceremony to honor Tony Gwynn for joining the 3,000-hit club and the Padres' star later delivered an RBI single for career hit 3,008, moving him into 20th place past Al Kaline.

REDS 5, PHILLIES 4: Mike Cameron, Dmitri Young and Sean Casey hit consecutive one-out singles in the bottom of the ninth to rally Cincinnati at home. The Reds won for the 14th time in 19 games.

PIRATES 6, ASTROS 5: Houston made two errors in the 13th inning, allowing Brian Giles to score the winning run for the visiting Pirates.
