Ian Desmond's two-run double in the eighth inning was the difference, as Washington claimed a 4-3 victory on Wednesday, putting an end to Miami's six-game win streak in the finale of a three-game series.
Jayson Werth and Anthony Rendon added an RBI each, while Denard Span walked twice and scored two runs for the Nationals, who avoided a sweep but nearly coughed up a three-run edge in the bottom of the ninth inning.
