MIAMI -- Michael Morse snapped a tie with an eighth-inning RBI single as the Miami Marlins defeated the New York Mets 4-3 Tuesday night at Marlins Park.

The Marlins beat the NL East-leading Mets for the first time in six meetings this season.

Mets reliever Carlos Torres (1-1) helped Miami by walking two batters in the eighth. Morse, the Marlins' first baseman, then lined a one-out single to center for his first RBI in eight games.

Marlins reliever Bryan Morris (3-0) pitched a scoreless eighth inning. Closer Steve Cishek earned the save -- just his second of the season -- by pitching a scoreless ninth.

Both starting pitchers -- Mets rookie Rafael Montero for the Mets and the Marlins' David Phelps -- got no-decisions despite faring well early. Montero held the Marlins scoreless through five innings. Phelps held the Mets scoreless through six.

Miami (9-12) opened the scoring with three runs against Montero in the sixth. Second baseman Dee Gordon singled, advanced to second on an error by right fielder Curtis Granderson and to third on a sacrifice bunt.

The Mets (15-6) could have intentionally walked right fielder Giancarlo Stanton to set up a potential inning-ending double play. Instead, they pitched to him, and Stanton singled for a 1-0 lead.

Stanton came around to score on a single by catcher J.T. Realmuto, and Miami got its third run when reliever Buddy Carlyle unleashed a wild pitch.

New York tied the score with three runs off Phelps and reliever A.J. Ramos in the seventh. The Mets loaded the bases on singles by right fielder Kirk Nieuwenhuis, catcher Anthony Recker and right fielder Curtis Granderson.

Recker's hit was dubious -- it could have been ruled an error on third baseman Martin Prado -- and the Mets made Miami pay with a bases-clearing double to deep center by Juan Lagares.

NOTES: The Mets sent INF Danny Muno to Triple-A and activated RHP Rafael Montero for Tuesday night's start. ... Mets RHP Bartolo Colon, 42, is 37-19 since turning 40 and will try to improve to 5-0 this season when he faces Miami and RHP Mat Latos in Wednesday's series finale. ... Mets RHP Bobby Parnell, who had Tommy John surgery on April 8, 2014, was shut down recently because of forearm fatigue. However, Parnell expects to resume throwing on Thursday. ... The Marlins, who designated C Jarrod Saltalamacchia for assignment Monday, have 10 days to try to trade him before he is put on waivers. Reports indicate there is some interest, but the Marlins would have to pick up most of the remaining salary ($14.2 million over two years). ... RHP Steve Cishek, Miami's struggling closer, said his velocity is down "a tick" -- from 92 mph to 89 mph on his sinker -- but added he normally starts slowly during the first month of the season.
