In front of a record crowd filled with many fans who were rooting for the other team, the Washington Nationals suffered through a mistake-filled 5-0 loss to the Philadelphia Phillies at Nationals Park. The Nationals allowed two unearned runs to score in the top of the fourth inning, then allowed three more in the sixth inning for the final margin.
Things started to go badly in the fourth. The Nationals appeared to catch John Mayberry in a rundown, but Ian Desmond dropped the throw and Mayberry was safe. After a Carlos Ruiz walk, Wilson Valdez tripled to bring in both runs. The Nationals surrendered three more in the sixth inning after a solo home run by Hunter Pence and two more RBIs to bring home runners John Lannan allowed to reach base.
The listed attendance was 44,685, the largest in team history. However, a vast majority of those fans were Phillies fans traveling down from Philadelphia to attend the game.
