Early on Saturday morning, the Nationals scored one of their most uplifting victories of the year, rallying for six runs in the ninth inning against Phillies closer Ryan Madson and winning on a walk-off grand slam from Ryan Zimmerman. About 20 hours later, they finished one of their ugliest performances at home - or, at least it was home in name only.
They fell 5-0 to the Phillies, watching Roy Oswalt shut them out for eight innings. And they lost before a Nationals Park-record 44,685 fans, many of whom were here to cheer on the Phillies.
John Lannan kept the Nationals close early, but gave up three runs before giving way to Collin Balester.
