The Dodgers cut Atlanta's lead in the National League West Division to 1 1/2 games today with a 2-0 victory as Bob Welch checked the Braves on three hits for eight innings and Ken Landreaux scored twice after stealing second base.

The victory was Los Angeles' sixth in a row and 10th in 11 games, as well as its ninth straight over Atlanta. The Dodgers swept this four-game series, after taking four straight in Atlanta last week. They were 10 1/2 games behind the Braves on July 30.

"It has to be the greatest heist since the Brinks Express robbery," said Dodgers Manager Tom Lasorda. "I've never seen a team pick up so many games in so short a period. It has been a tremendous effort by all our players.

"But we still have hills to climb; you're nobody until you're in first place."

Welch (13-7) retired the first 13 batters he faced before giving up a single to Bob Horner in the fifth. Tom Niedenfuer pitched the ninth inning for his sixth save.

Loser Rick Camp (8-5) allowed four hits the first two innings, then retired 10 in a row, giving up six hits in his seven innings.

With one out in the first, Landreaux beat out an infield grounder to short, the call at first being protested loudly by Atlanta Manager Joe Torre. Landreaux stole second, got to third on Dusty Baker's fly to center and Pedro Guerrero singled to right.

The Dodgers scored again in the eighth when, with one out, Steve Sax singled and was forced by Landreaux. Landreaux stole second and scored on Baker's single to left.

The Braves mounted a threat in the seventh but were thwarted. Terry Harper led off with a single and the next batter, Rafael Ramirez, singled. Chris Chambliss then lined a ball off Welch's glove. Shortstop Mark Belanger charged in, scooped up the ball and threw out Harper at the plate. Dale Murphy grounded out and Horner flied out.
