Hubie Brooks drove in three runs and Bill Gullickson pitched a five-hitter yesterday in Montreal to lead the Expos to a 6-1 victory over the Dodgers, ending the eight-game winning streak of Los Angeles starter Bob Welch.

Gullickson (12-9) walked three and struck out three in pitching his third complete game of the season.

"When I woke up this morning, I didn't even think we were going to play," said Gullickson, referring to rain that fell most of the night and up until game time. "That's what AstroTurf will do for you."

After scoring single runs in the first, third and fourth innings off Welch (9-2), the Expos took a 6-0 lead in the seventh. Vance Law doubled and scored on a single by Andre Dawson. Brooks then tripled to score Dawson for his 74th RBI of the season, a career high. Terry Francona's run-scoring single made it 6-0.

"It surprises me that I hit my career high this year," said Brooks, who took over the cleanup position in Montreal's batting order from Gary Carter, now with the Mets. "Of course, it's a pleasant surprise for me because I'm batting cleanup. It's always good to know you've done better than the year before."

Dodgers Manager Tommy Lasorda was ejected in the sixth by third base umpire Dana DeMuth for arguing a call at third in which R.J. Reynolds was thrown out.

The Dodgers scored in the ninth on singles by Mariano Duncan and Mike Marshall, a walk to Pedro Guerrero and a sacrifice fly by Greg Brock.
