Mike Pelfrey surrendered a fourth-inning grand slam to Marlins newcomer John Buck and Marlins ace Josh Johnson held the Mets hitless until Willie Harris’ leadoff double in the seventh as Florida won, 6-2, in the first major league game managed by Terry Collins since 1999.
The Mets had won five straight Opening Days, the longest active streak in the majors.
Since Angel Pagan’s grand slam off Arizona’s Clay Zavada on Aug. 1, 2009, the Mets have served up 17 straight unanswered grand slams to opponents. The 12-0 disparity last season was the largest by a team that failed to muster a grand slam in major league history, according to the Elias Sports Bureau.
The only team to be no-hit on Opening Day remains the 1940 White Sox, who were victimized by Bob Feller.

• ALL RIGHT: Carlos Beltran started his first major league game in right field since Sept. 30, 2000 against the Kansas City Royals.
He went 1-for-4 on Friday night, and accounted for the Mets’ opening run by driving in Harris with one out in the seventh with a double off Johnson into the right-field corner.
Beltran played a full game Friday -- more than either of his two Grapefruit League games at the position this week (five and six innings).
Beltran had an uneventful night in the field, but an active first inning. He recorded the Mets’ first two outs of the season, on routine fly balls by Omar Infante and Hanley Ramirez.
In his first at-bat, Beltran took two pitches, then had a foul pop-out to third base. He then grounded out to second base two innings later.
• DEBUTANTS: Second baseman Brad Emaus and right-hander Pedro Beato, both Rule 5 picks, made their major league debuts.
In his first major league at-bat, Emaus grounded out to Ramirez at shortstop in the second inning to strand Ike Davis at second base after a two-out walk to the first baseman, then a balk. Emaus finished 0-for-2 with a walk.
An unaccomplished second baseman, Emaus also was 5-for-5 in fielding chances, including a nifty lunge to his left with the infield in to hold Buck at third base in the sixth to help keep Beato’s career major league ERA 0.00.
Beato’s first pitch as a major leaguer, to open the sixth, was laced for a double off the wall in left-center by Buck. But Buck ended up being stranded when, following Emaus’ solid play on the infield grass, Chris Coghlan had an inning-ending flyout to center.
Beato then tossed a scoreless seventh, benefiting from Emaus initiating a double play after fielding Ramirez’s grounder.
• SEVENTH HEAVEN: Harris started in left field because of his career .500 on-base percentage against Johnson. He went 1-for-3 against the ace (and 2-for-4 overall), including the leadoff shot in the seventh that broke up the no-hit bid. To that point, the Mets’ lone runner had come on a two-out walk to Davis in the second.
Lucas Duda, who had a pinch-hit flyout, is expected to start in left field Saturday.
New York Mets
• DISAPPOINTING: Pelfrey was charged with five earned runs on four hits and four walks while striking out two in a 97-pitch effort over 4 1/3 innings.
It marked the shortest Opening Day outing by a Met since Tom Glavine’s debut with the organization on March 31, 2003 at frigid Shea Stadium against the Chicago Cubs, when the ex-Brave allowed five runs in 3 2/3 innings.
Pelfrey, who took the loss, had raced to a 9-1 start last season. He has a 5.63 ERA in 13 career starts against the Marlins. Pelfrey next draws Joe Blanton on Wednesday in Philadelphia.
The final run charged to Pelfrey perhaps should have been unearned. Blaine Boyer, who replaced Pelfrey, coaxed a two-out grounder from Gaby Sanchez in the fifth. The hop ate up Davis at first base and was scored a hit as Florida took a 5-0 lead.
The tone was set right away in a 25-pitch first inning by Pelfrey, in which he stranded two runners in scoring position. He opened the frame with a 10-pitch walk to Coghlan.
• MET FAN: David Wright aimed to reduce his strikeout total after a career-high 161 in 2010. There’s no shame given the opposing pitcher, but Wright K’d in his first two ABs of 2011 as well -- on a sharp-breaking curveball looking, then swinging at a 97 mph fastball from Johnson.
• HAMMY WHAMMY: Marlins right fielder Mike Stanton left the game after five innings with a tight left hamstring.
• PATIENCE: Perhaps as a sign of the plate discipline being preached, nine of the game’s first 10 Mets batters took the first pitch. Only Pagan swung at Johnson’s first offering. Reyes, a relatively free swinger, actually took the game’s first five pitches before grounding out on a full-count offering.
• MET KILLER: Johnson, last year’s NL ERA leader, improved to 8-1 in 13 career starts against the Mets.
• BUCH SHOT: Taylor Buchholz, in his debut as a Met, served up a homer to Logan Morrison -- the first batter he faced.
• K-ROD TRACKER: Francisco Rodriguez has finished none of the Mets’ first one games. He needs 55 games finished in the final 161 games in order for his contract to vest for 2012 at $17.5 million.
• NEXT: Game 2 of the series is Saturday at 7:10 p.m., with left-hander Jon Niese facing Marlins right-hander Ricky Nolasco.
