MIAMI -- With three-time Cy Young Award winner Pedro Martinez heading to the 15-day disabled list, the New York Mets know they'll need someone to step up. On Wednesday night, the hitters did their part.
Church had three hits and drove in three runs, and every Mets starting position player had at least one hit and scored at least once.
Martinez was placed on the 15-day disabled list because of a left hamstring strain before the game. He is expected to miss four-to-six weeks.
"We're going to miss Pete," Mets shortstop Jose Reyes said. "But we have good talent here. We have to continue playing like we did tonight."
Andrew Miller took the loss, giving up five runs and eight hits over 4 1/3 innings in his Marlins debut. Miller was acquired from Detroit in the offseason.
The Mets jumped on Miller to take a 3-0 lead in the second, highlighted by Church's two-run homer.
"I threw a breaking ball right down the middle to him and he did what he was supposed to do with it," Miller said. "That was a pretty poor effort on my part. Not what I wanted to do tonight."
Church said his home run came on a slider.
"He did me a little favor because those first two fastballs were already in the catcher's glove by the time I swung," Church said. "I was just able to stay on that pitch."
Oliver Perez allowed five hits over six scoreless innings to pick up a win in his season debut. Nelson Figueroa, whose contract was purchased from Triple-A New Orleans prior to the game to replace Martinez, pitched a perfect inning. Pedro Feliciano and Billy Wagner finished up the six-hitter.
It was the largest shutout deficit at home in the history of the Marlins franchise.
"It was an important win because we won the series and have an off day tomorrow," said Perez, who likely will start the Mets home opener April 8th because of Martinez's absence. "I have to be ready to play. We have five days to get stronger."
Wright's three-run homer off Lee Gardner capped a five-run sixth inning.
"It was a great, great game for everybody," Mets manager Willie Randolph said. "The guys swung the bats a little bit."
Beltran appeared to hit a two-run home run off relief pitcher Matt Lindstrom in the fifth. The ball appeared to clear the right-field wall and bounce off a railing and back onto the field. It was initially ruled a home run by third base umpire Jeff Kellogg. The umpires discussed it and crew chief Rick Reed ruled it a ground-rule double. It drove in Wright to make the score 5-0.
"It's funny, the guy closer to the ball saw it as a home run and then the other guys overruled him, which I don't understand," Randolph said. "They were furthest from the play."
As it turned out, it didn't make much difference.
"That's a pretty good lineup they run at you," Marlins manager Fredi Gonzlez said. "When you give them pitches to hit they're going to put some damage on you."
Florida's Robert Andino, who hit a 10th-inning walk off homer in Tuesday's 5-4 win over the Mets, quickly left the locker room after the game because of a text message from his wife that an intruder was attempting to enter their Miami home. He downplayed the incident before Wednesday's game. "Everything is okay, nothing really serious," he said. ... Wright extended his hit streak to 20 games, dating back to Sept. 19, 2007. ... The Marlins previous worst shutout loss at Dolphin Stadium was a 12-0 loss to Houston on July 15, 2006.
