Manager Willie Randolph hoped for an easy game on Sunday against the Marlins, with the Mets playing shorthanded. And that's what he got. The Mets used a four-run fourth inning to breeze past the Marlins, 6-4, before 23,622 at Dolphin Stadium.

With two players sidelined by injuries, five Mets drove in a run and right-hander Jorge Sosa resumed his winning ways, as the visitors completed a three-game sweep of the Marlins.

With the Braves losing, the victory -- their seventh straight against the Marlins in Florida -- gave the Mets their biggest lead in the National League East, 4 1/2 games.

Sosa gave up two runs in 5 2/3 innings in improving to 4-1 on the season. He was particularly sharp for the game's first four innings, allowing just two runners. The Marlins got the first two runners on in the sixth, and then the next two hitters hit shots to the warning track in left field.

That was it for Sosa. Left-hander Pedro Feliciano came on to get the final out. The Marlins managed only an eighth-inning run the rest of the way.

Carlos Delgado, who drove in five runs on Saturday night, produced the first Mets run with a single in the fourth inning. Damion Easley followed with a run-scoring single, and a third run scored on second baseman Dan Uggla's error. Endy Chavez capped the rally with an RBI single.

David Wright hit a 3-0 pitch for a run-producing double in the fifth, and pinch-hitter Julio Franco's single scored the Mets' final run in the eighth.
