Phillies pitcher Cole Hamels was saddled with a loss Sunday despite giving up just one unearned run on four hits and one walk in seven innings and striking out six in his team's 4-0 defeat against the Nationals.

Hamels (6-6) was a runner reach first base with one out in the third inning on an error by the third baseman, and that runner would come around to score. Hamels has given up a total of two earned runs in 30 innings over his last four starts. He owns a 2.42 ERA, 1.11 WHIP and 139:40 K:BB ratio in 137 1/3 innings. Hamels is scheduled to face the Mets Saturday.
