Dusty Baker drove in five runs with two homers and a single yesterday, powering the Los Angeles Dodgers to their fourth straight triumph, a 10-8 victory over the host Montreal Expos.

Baker, who had four RBI in the Dodgers' 6-2 victory over Montreal Friday night, went five for six with two runs scored; he is seven for 10 in his last two games.

"I like Montreal, it's a great city," said Baker. "It's funny because I haven't had a whole lot of success in this city. And up until last night I never hit a home run here. But the law of averages is going to catch up to you."

He gave Los Angeles a 1-0 lead in the first inning with his fifth home run of the year. In the third, after Montreal moved ahead, 3-1, on Gary Carter's three-run homer, the Dodgers sent up nine men and scored four runs. Steve Sax and Steve Garvey singled before Baker hit his second homer, pushing the Dodgers ahead, 4-3.

Loser Bill Gullickson (2-2) gave up a walk to Rick Monday and a single to Pedro Guerrero before Bill Russell singled in another run, giving Los Angeles a two-run lead.

The Dodgers sent 10 batters to the plate in the fourth and again scored four times. Garvey's two-run homer followed a walk to Sax to make it 7-3. Steve Yeager singled in two more runs.

In the fifth, the Expos rallied to within 9-8 by scoring five runs. Baker singled in the Dodgers' final run in the ninth.
