It was all tied up at 2-2 in the 10th when Bryce Harper singled to start the frame and Daniel Murphy followed with an opposite field double that fell in for a walk-off winner as the Washington Nationals took the series opener from the Philadelphia Phillies, 3-2 in the nation's capital. Stephen Strasburg put together another solid seven-inning outing and the Nationals' bullpen combined for three scoreless on the way to the win. Nationals now 6-4 on the season.
