Mark Buehrle's chances to win his fourth straight start didn't last very long at all.
Jason Bay hit his fifth career grand slam in the Mets' five-run first inning and New York earned a three-game series sweep over the Miami Marlins with a 5-1 win on Sunday.
"All hell broke loose in the first inning, but you just have to realize you have to settle down and, if you want to have any chance of coming back, you can't give up any more," Buehrle (12-12) said.
Ronny Cedeno led off the game with a double to deep center field and took third on Justin Turner's double. Turner hit a fly down the right-field line, where the ball landed just inside fair territory as right fielder Mike Stanton overran it.
Cedeno scored on David Wright's groundout. Following Scott Hairston's pop out, Buehrle walked Ike Davis and hit Kelly Shoppach with a pitch to load the bases.
"It was a little different out there today," Stanton said. "There were a few balls that got mixed up. I don't know if it was me or what, but the balls came out there a little different."
Buehrle refused to blame Stanton for the Mets' big inning.
"He has saved me a number of runs and hits with his play out there all season and, when something like that happens, you try to pick your defense up," Buehrle said.
Chris Young (4-7) allowed one run and five hits in five innings. He walked one and struck out three as the Mets won for the seventh time in eight games.
"Young was elevating his fastball, and we kept hitting fly balls. We couldn't make adjustments and he came out and pitched a good game against us," Marlins manager Ozzie Guillen said.
The Mets wasted little time in getting to Mark Buehrle (12-12).
Bay then drilled a 1-0 pitch into the right-center-field seats for his seventh home run. He went 2 for 4 and raised his average to .160 with 18 RBIs.
Now in the third year of a guaranteed four-year, $66 million contract, Bay has been reduced to a platoon player. He has played in 55 games this season, and has spent two stints (concussion, fractured rib) on the disabled list.
Buehrle gave up five runs and six hits in seven innings. He walked one, struck out three and hit a batter.
Justin Ruggiano's two-out double in the fifth scored Rob Brantly with Miami's run. Brantly walked and took second on Buehrle's sacrifice bunt.
Miami has dropped four in a row and eight of 10.
