Braves 6, Nationals 2: The Nationals got no relief, quite literally, from their recent woes last night. Jorge Sosa (1-1) and Sean Burnett sullied a solid effort by starter Craig Stammen by allowing four runs in the seventh and eighth innings, Nyjer Morgan was picked off first to cut the legs off a ninth inning rally, and Atlanta completed a quick two-game sweep of Washington last night. Stammen — who had posted an ERA over 15 in his previous three starts — pitched very well, only allowing a couple of solo home runs, and Rafael Ronnie Belliard’s single tied the game at two in the top of the seventh. But the bullpen couldn’t hold the Braves in check — first Sosa, who allowed Adam LaRoche’s second longball of the night, and then Burnett, who allowed three runs to really seal the loss. In what was probably his most forgettable game with the team to date, Morgan had a rare bad game: besides being caught off first to make the final out, he was also caught stealing once and left men on in scoring position with two outs twice. For the second night in a row, the Braves got fantastic starting pitching. Derek Lowe (12-7) really had the sinker working, coaxing three double plays and getting a little bit of revenge for two losses to the Nats earlier this season. Perhaps an upcoming four-game set in Cincinnati can right the ship.
