R.A. Dickey was again on the mound to yet again halt a Met losing streak.  Gio Gonzalez threw for Davey Johnson's first place Nationals.With Lucus Duda in the minors and Manny Acosta in the bullpen and Tejada riding the pine after yesterday's take out slide, the Mets needed win in the worst way....they didn't get it.Scott Hairston began the bottom of the second when he reached first on an error, he later stole second.  After Ike Davis and (surprise, surprise) Jason Bay struck out, Ronny Cedeno poked a ball over the first base bag that scored the first run of the game and the only Met hit until the seventh inning. The Nats got to Dickey when  Zimmerman hit a double and scored on a Espinosa double later in the inning.  The Met offense was asleep.  The Nat offense waited until the sixth inning when Dickey gave up five straight two out hits that included a Adam LaRoche two run bomb over the Pepsi Porch.  Dickey would exit the game after six innings, and despite striking out seven batters, gave up five earned runs.Manny Acosta took over for Dickey for seventh a pitched a scoreless frame,  With two outs in the seventh, Ike Davis hit the second Met hit in the and Jason Bay drew a walk but the two out magic didn't fall from the skies as Ronny Cedeno hit a weak grounder to end the Met threat.  Josh Edgin pitched a scoreless eighth striking out three even though he gave up two hits.Jordany Valdespin set a Met record when, in the bottom of the eighth inning, he hit his 5th pinch hit home run.And that was it as the Mets would fall to the Nats again and fall three games under .500.
