Andre Dawson hit a two-run homer and Hubie Brooks delivered a two-run single yesterday in Montreal as the Expos moved into first place in the National League East and completed a three-game sweep of the New York Mets with a 7-2 victory.

The Expos, in winning their fifth straight game, moved one game ahead of the Chicago Cubs.

"I'm just glad we beat them to prove a lot of people wrong," Brooks said. "I feel good, no doubt about it. All the guys here are doing the job well, and in order for us to win, that's what we have to do."

Montreal scored three runs in the first inning and three more in the fifth against Rick Aguilera (1-1), who made his first major league start.

A one-out walk by Vance Law in the first preceded Dawson's ninth homer. One out later, Brooks, who came to Montreal in the trade for Gary Carter, singled, then scored on a double by Tim Wallach.

In the fifth, Miguel Dilone, pinch-hitting for Expos starter Bill Gullickson (7-5), walked and took second on a balk by Aguilera before scoring on Tim Raines' single.

With one out, Dawson's sharp grounder took a bad hop past second baseman Wally Backman, who was charged with a two-base error. After Dan Driessen was intentionally walked, Brooks got his two-run single.

Gullickson allowed three hits but walked four in five innings. Mickey Mahler pitched the final four innings for his first save.

The Mets got a third-inning run on a sacrifice fly by Keith Hernandez and another in the seventh on Backman's RBI force out.

"At least we're going home," said Carter, who returned to Montreal for the first time after being traded for four players last winter. "It's always frustrating when you're in a rut like we are right now."
