The Mets tacked on another run in the fifth. With Cesar Jimenez on the mound, Murphy doubled to right and crossed the plate on Brown's single to right.
New York scored two more runs off Jimenez in the sixth. Recker walked, moved to second on a sacrifice bunt, advanced to third on Young's single to shallow left field and scored on a Jimenez balk. Murphy followed with an RBI-single to left.
Philadelphia finally got on the board in the seventh. Chase Utley and Domonic Brown hit back-to-back singles to start the inning. Utley moved to third when Carlos Ruiz flied out and scored on Ruf's sacrifice fly.
The Mets, however, responded with four runs in the bottom half. With the bases loaded and one out, Omar Quintanilla walked to force in a run. After pinch- hitter Ike Davis struck out swinging, Young cleared the bases with a triple to right.
