NEW YORK (AP) -- Carlos Beltran hit a two-run homer with two outs in the 13th inning, and the New York Mets overcame another blown save by Billy Wagner to snap a five-game losing streak with a 5-3 victory last night over the Arizona Diamondbacks.

The Mets chased a bruised Brandon Webb early and took advantage of a key error by third baseman Mark Reynolds, who tied it by hitting a three-run shot off Wagner with two outs in the ninth inning.

That cost Mike Pelfrey a win in the best outing of his big league career, but New York refused to fold and avoided falling four games below .500 for the first time since September 17th, 2005.

Luis Castillo hit a hard one-hopper into Reynolds' midsection with one out in the 13th and reached safely when the ball trickled away.

David Wright fouled out but Beltran lined a 1-2 pitch from Edgar Gonzalez to right-center for the fifth game-ending homer of his career.

With two on in the top of the 13th, Claudio Vargas got Conor Jackson to ground into an inning-ending double play.

The NL West leaders have dropped 15 of 22.
