MIAMI -- Heriberto Hernández hit a walk-off grand slam to center with one out in the ninth on Sunday to lead the Marlins to a 4-0 win over the Mets at loanDepot park to finish off a three-game sweep.
Christopher Morel led off the inning with a double into left field off reliever Devin Williams; Liam Hicks then walked with one out. Williams intentionally walked Xavier Edwards to load the bases and set the stage for Hernández.
The Mets, who have lost five of the past six, have been held to just 10 runs in their past seven games against the Marlins dating to Aug. 31 of last season.
The Marlins have won nine of 11 against the Mets since April 2025.
New York scored a total of two runs against the Marlins in this three-game series.
The Mets had few chances to score Sunday, but in the ninth, MJ Melendez led off with a single -- only pinch-runner Nick Morabito was thrown out trying to steal second.
Luis Torrens walked with two outs and took second on a wild pitch, but the threat ended when Carson Benge struck out looking.
Christian Scott, who grew up about 45 minutes north of the Marlins’ ballpark in suburban Broward County, had the best start of his young career at loanDepot park.
He left the scoreless game with two outs in the sixth after allowing four hits and striking out five. He entered the game with a 0-2 record and 7.88 ERA in two previous starts at his hometown ballpark.
The Mets’ bullpen was strong on Sunday, with Huascar Brazobán, Brooks Raley, and Luke Weaver keeping the Marlins off the board after Scott departed.
Williams took the loss after coming in for Weaver to pitch the ninth.
New York was playing without Juan Soto, who was a late scratch from the finale with flu-like symptoms.
