Josh Edgin (1-0) got his first major league victory.

Hairston hit a tying homer in the eighth and pinch hitter Justin Turner and Rob Johnson also drove in runs in the inning against Sergio Romo.

Hairston has 14 home runs against the Giants, his most versus any team. Romo was tagged for four runs, matching what he had allowed in his previous 30 2-3 innings.

Bobby Parnell gave up Posey's double and Edgin allowed Schierholtz's tying hit, giving the Mets their 17th blown save.

Ronny Cedeno added two RBIs for the Mets. Marco Scutaro and Ryan Theriot each had two hits and drove in a run for the Giants.
