Mike Piazza lined an RBI double in his Mets debut and, playing in front of a Shea Stadium crowd swelled past its usual size, Al Leiter pitched New York past the Milwaukee Brewers 3-0 Saturday.

Piazza, acquired a day earlier in a trade with the Florida Marlins, drew loud ovations all afternoon in going 1-for-4. The crowd of 32,908 - the Mets had been averaging 18,278 - included nearly 13,000 walk-up fans and Jerry Seinfeld."It was real exciting for me, these people are awesome," Piazza said.

Leiter (4-3) pitched a four-hitter for his first shutout since throwing a no-hitter for the Marlins on May 11, 1996. The left-hander won for the first time in five starts.

The Mets won their third straight game and sent the Brewers to their fourth loss in a row.

Piazza, who arrived at the ballpark just two hours before the game because of a plane mixup, grounded out and struck out before rewarding his new fans with his first hit for the Mets, a solid double to the right-center field gap in the fifth that made it 2-0.

Jeff Juden (5-3) took the loss.
