NEW YORK (AP) -- The New York Mets hardly missed Mike Piazza and Cliff Floyd in their home opener.

Newcomers Kaz Matsui and Mike Cameron each drove in two runs, Steve Trachsel was terrific on the mound and at the plate, and the Mets beat the Atlanta Braves 10-6 Monday.

Todd Zeile added three hits as a makeshift lineup roughed up former Mets pitcher Mike Hampton in building a surprising 10-0 lead.

"I think the guys that were in there feel that they can play," Zeile said. "I think it helps that even though some of our big guns were down, nobody was hanging their heads."

New York played without Floyd, who was placed on the 15-day disabled list with a strained right quadriceps after getting hurt Sunday against the Expos in Puerto Rico.

Piazza was out of the lineup because of a sore right elbow following a collision with Peter Bergeron at first base Sunday. And the Mets already were without second baseman Jose Reyes, on the DL with a strained right hamstring, and right fielder Karim Garcia, day to day with a broken left ring finger.

That left Ricky Gutierrez, Shane Spencer and Zeile as the 2-3-4 hitters -- not exactly the players a sellout crowd of 53,666 hoped to see when it showed up in a chilly drizzle.

But Mets fans were excited about the home debuts of Matsui and Cameron, who came through along with the backups.

"I tell you what, I hadn't been that nervous since my first at-bat my rookie year," Cameron said. "It was electrifying. They're in every pitch.

"It was one of those special feelings -- what I'd been looking forward to since I signed."

J.D. Drew homered and Johnny Estrada hit a three-run shot in the eighth inning -- the first for each as a member of the Braves -- but it was too late.

Hampton (0-1) was knocked out in the third and booed as he walked off the mound with his head down. Fans at Shea Stadium haven't forgiven him for leaving town as a free agent after helping the Mets reach the 2000 World Series.

"That doesn't bother me," Hampton said. "They're fans and they're rooting for their team."

The left-hander threw 80 pitches in 2 2-3 innings, giving up seven runs and nine hits.

"I made mistakes and I paid for it," he said.

Trachsel (1-1), hit hard in an 18-10 loss at Atlanta in his first start, was much better this time. He allowed one run and four hits in six innings, and also drove in two runs.

"His splitter was working well. He kept pitches down," Braves slugger Andruw Jones said.

Atlanta scored once in the ninth on pinch-hitter Eddie Perez's RBI single, but Braden Looper came in and got Jones to ground into a game-ending double play with the bases loaded for his second save in two days.

"It's definitely a confidence booster -- first game in New York -- and this whole game is confidence," Looper said.

The Mets jumped ahead on Cameron's two-out, RBI single in the first. Trachsel hit a run-scoring double down the third-base line in the second, and Gutierrez added an RBI groundout.

Hampton walked Joe McEwing with the bases loaded in the third, Trachsel had an RBI grounder and Matsui, the newcomer from Japan, broke it open with a two-run double.

"It was amazing. The crowd was really into it. I was really nervous at first but it was really fun," Matsui said through a translator. "I almost had goosebumps all over."

Cameron drove in a run with a double to deep center in the fourth, and Jason Phillips followed with an RBI single.

Spencer added an RBI double in the fifth.

"It's a good thing we put 10 on the board," Cameron said.

The Braves were missing three injured regulars themselves: left fielder Chipper Jones (strained right hamstring), shortstop Rafael Furcal (strained lower back) and first baseman Adam LaRoche (sore foot).

Manager Bobby Cox hopes all three can return to the lineup Wednesday.

"It was just an awful day," Andruw Jones said.
