MONTREAL (Ticker) -- Jose Lima finally was done in by the long ball.

Brian Schneider hit a three-run homer in the sixth inning - Montreal's fourth of the game off Lima - and the Expos' bullpen pitched six scoreless innings as Montreal posted a 6-3 victory over the Los Angeles Dodgers .

"The home run ball got us tonight," Dodgers manager Jim Tracy said. "That's what it boils down to. When they hit the ball out of the ballpark, you don't have a lot of defense for that."

With the score tied, 3-3, and one out in the sixth, Terrmel Sledge and Alex Gonzalez had consecutive singles off Lima (11-4). One batter later, Schneider deposited a 3-1 pitch over the right-center field wall to put the Expos ahead.

"I wanted to get that run home, so I wanted to put a good swing on it," Schneider said. "It just so happened that I hit it out."

Joey Eischen and Joe Horgan (4-1) each worked two scoreless innings in relief of Montreal starter Tony Armas Jr., who left the game after the third with spasms in his right leg.

Luis Ayala recorded the final six outs for his second save.

"Tony said he couldn't go anymore," Montreal manager Frank Robinson said. "The three guys closed it out and we didn't even need the fourth guy, so that was a good sign for us."

Lima, who was 5-0 in his previous 10 starts despite allowing 13 home runs during the span, allowed a leadoff homer by Brad Wilkerson and back-to-back blasts by Tony Batista and Juan Rivera in the third.

"It's tough," Lima said. "I'll take all the blame for this one. When they needed me the most up there, I didn't do my job."

The righthander ranks third in the National League with 27 homers allowed in 139 2/3 innings this season.

"Home runs don't bother me," Lima said. "Even the three-run homer. I don't walk anybody."

Adrian Beltre had two hits to extend his hitting streak to 11 games for the Dodgers, who have lost three of four.

The win was the 900th of Robinson's managerial career, making him the 58th to reach the milestone.

"I didn't even know anything about 900," Robinson said. "It's a nice feeling to say I've been able to last this long in this position and be on some good ballclubs."
