Dusty Baker had a home run and knocked in four runs and Ken Landreaux homered and drove in three as the Los Angeles Dodgers won in Atlanta, 11-2, last night, stretching their NL West lead to 5 1/2 games over the Braves.

The Dodgers reduced their magic number for clinching the division title to five as they continued their mastery over Atlanta, lifting their season series lead to 11-5.

"We couldn't afford to lose tonight, but we got blown out," said Atlanta Manager Joe Torre. "There's no ifs, ands or buts about it."

Los Angeles has nine games remaining; the Braves have 10.

Jerry Reuss (12-11) allowed nine hits, struck out four and walked none in going the distance to improve his lifetime record against Atlanta to 17-8.

Los Angeles took a 1-0 lead in the first when Steve Sax singled up the middle, stole second, went to third on a wild pitch by Len Barker and scored on a sacrifice fly by Baker.

The Dodgers chased Barker (1-3) with three runs in the third. A single by Sax and walks to Bill Russell and Baker loaded the bases before Sax scored on Landreaux's ground out. Mike Marshall followed with a two-run triple, his first three-base hit of the season.

Landreaux had his 17th homer in the fifth following a single by Pedro Guerrero, who hit his 31st homer in the eighth.
