But Moyer (4-5) had one his best starts of the season Sunday, striking out four and walking none while registering a season-low hits allowed. It was Moyer's first win since April 26.
The Phillies (28-20) have won seven straight against Washington and 10 of 12 this season against major league baseball's worst team.
