Nats Nightly: Nationals 2-1 over Phillies on Bryce Harper walk-off double

Washington Nationals' right-hander Stephen Strasburg struck out 13 batters in eight innings of work, but gave up a run before he was done as the Philadelphia Phillies tied it up and it went to extras before Bryce Harper hit a walk-off double to give the Nats a 2-1 win... meanwhile, in Cincinnati, the New York Mets clinched the NL East.
