Mets 5, Giants 4: Josh Satin drilled a two-run, two-out single in the ninth inning to cap a four-run outburst as host New York snapped San Francisco’s four-game winning streak.

Giants reliever Santiago Casilla walked two batters in the ninth and closer Sergio Romo (4-8) entered with one out and allowed an RBI double to Zach Lutz and a run-scoring single to Juan Centeno. Romo retired Omar Quintanilla on a short fly to right and was one strike from nailing it down before Satin ripped a pitch down the left-field line to drive in Anthony Recker and Matt den Dekker.

New York relievers combined for four hitless innings with Vic Black (2-0) pitching the ninth. The rally prevented San Francisco’s Matt Cain from earning a victory after allowing one unearned run and six hits in 7 2/3 innings.

Gregor Blanco hit a two-run homer off Aaron Harang in the third inning and San Francisco made it 3-0 in the fourth when New York right fielder Andrew Brown dropped Blanco’s two-out fly to allow Brandon Crawford to score from second. The Giants added another run in the fifth on Crawford’s run-scoring single.

The lone run off Cain was unearned and crossed on Satin’s sacrifice fly in the eighth.

GAME NOTEBOOK: San Francisco OF Hunter Pence struck out three times while seeing his seven-game hitting streak halted. … Harang struck out eight in five innings in his second start for the Mets. He allowed four runs (three earned) and six hits. … Giants 2B Marco Scutaro (finger) missed his second consecutive game and is unlikely to play in Thursday’s series finale.
