"Henderson looked good," Marlins manager Mike Redmond said. "We're trying to get him comfortable on the mound. He threw a lot of strikes. He did exactly what we needed him to do. So it was a good day for him."
Stanton's first Grapefruit League hit, a single off the glove of third baseman Eric Campbell, was Miami's first hit of the game. Miami cashed in on a pair of Rafael Montero walks.
The Marlins have not announced their regular-season rotation, but Alvarez is regarded as a strong frontrunner. The right-hander was an All-Star last season, and assumed the role of ace after Jose Fernandez underwent Tommy John surgery in June. In two scoreless innings, Alvarez allowed one hit and struck out one. Efficient, he threw 22 pitches, with 16 strikes.
Matz got off to a wild start, hitting Dee Gordon with the first pitch he threw. But after Gordon stole second, Matz retired six straight in his two innings.
Kirk Nieuwenhuis had a double in the fourth inning for the Mets, and Dillon Gee threw 2 2/3 innings of one-hit, scoreless relief.
Up next: Jarred Cosart makes his first Grapefruit League start on Sunday. The Marlins will be the visitors against the Cardinals at Roger Dean Stadium in the 1:05 p.m. ET contest, broadcast live on Gameday Audio. St. Louis is starting Lance Lynn. Cosart is a middle-of-the-rotation candidate for Miami, and perhaps could be the No. 2 starter. He will throw two innings. Michael Morse and Marcell Ozuna were each out of the lineup on Saturday, and could be back on Sunday.
