Mike Marshall's RBI single with two out in the ninth inning yesterday helped the Dodgers end New York's five-game winning streak with a 7-6 victory over the Mets in Los Angeles.

The Dodgers increased their lead in the NL West to 8 1/2 games over Cincinnati and nine over San Diego.

In the East, the Mets trail St. Louis -- which lost last night -- by 1 1/2 games.

New York had tied it, 6-6, in the top of the ninth when Darryl Strawberry, who was four for five, lined reliever Tom Niedenfuer's 0-1 pitch for his 23rd homer of the season.

With one out in the bottom of the inning, pinch hitter Franklin Stubbs singled to left. After pinch runner Jose Gonzalez stole second, Terry Leach (2-3) struck out Dave Anderson and walked Ken Landreaux intentionally. Marshall, who earlier had homered, then singled to left for the game-winner.

Niedenfuer pitched two innings to improve his record to 7-5.

Dodgers shortstop Mariano Duncan was ejected in the sixth inning after being called out on strikes. He exchanged words with pitcher Ed Lynch, then charged the mound. Both benchs then emtied before play resumed.
