Moore, seeking a spot on the Opening Day roster, sent a two-out pitch over the right-field wall off Zack Wheeler. Ramon Cabrera later added a two-run blast in the decisive three-run eighth. Moore, who has gone deep five times in Grapefruit League play, tacked on a three-run homer off Fernando Salas in the ninth.
Miami scored five times against Mets starter Steven Matz in the first two innings before he settled down for a scoreless third and fourth.
"I felt good. It just happens," Matz said of the worst of his four Spring Training starts.
