Adam Jones delivered a two-out double in the 12th inning Friday that gave Baltimore a 4-2 victory over Washington. Baltimore ended a four-game losing streak and handed the Nationals their eighth setback in nine games. The Orioles put two runners on in the 10th without scoring, but broke through in the 12th after the first two batters of the inning had been retired. Pitcher Danys Baez reached on an infield single against Kip Wells (0-2) and went to third on a ground-rule double by Brian Roberts.
