Melancon came on to pitch the ninth with a 6-2 lead, and yielded a pair of runs on four hits, but managed to close out the game for the Nats.
The shaky outing was an unusual one for Melancon, who still holds a 1.57 ERA after Monday. Melancon has blown just three saves all year in 41 tries, so he can be forgiven for the poor inning in a non-save situation.
