Heading into the ninth inning of a long, dreary night at Nationals Park, the Nationals were down 4-2 to the Phillies, looking like they'd lose again at home before a largely pro-Phillies crowd.
And then Jayson Werth got a rally started with an 11-pitch at-bat, setting up another stage for Ryan Zimmerman to steal.
The Nationals' third baseman is no stranger to walk-off homers - he's got eight of them in his career now - but the one he just hit against the Phillies will go down as one of his most memorable. He clubbed a full-count grand slam in the bottom of the ninth against Ryan Madson to lift the Nationals to an 8-4 win.
Zimmerman has hit safely in 25 of 26 games, and he already had a double in the sixth inning tonight. He's on an unbelievable tear right now, and he saved his biggest moment to end the game.
More from the clubhouse in a little bit.
