Marlins 7, Nationals 0: Jose Fernandez retired the first 14 batters he faced and finished with seven innings of one-hit ball to lift host Miami to a series-opening win.

Fernandez (11-6) lost his perfect game on a two-out walk in the fifth and his no-hitter when Zach Walters - in his first career at-bat - reached on a pinch-hit infield single with two outs in the sixth. The rookie yielded just one other baserunner on a walk in the seventh and struck out nine en route to dropping Washington eight games behind Cincinnati in the race for the second wild card spot in the National League.

Miami gave Fernandez all he needed by jumping on Dan Haren (8-13) in the first, when two hits and a walk loaded the bases before Giancarlo Stanton drove in two runs with a single to center. Placido Polanco added a sacrifice fly later in the frame and Logan Morrison made it 5-0 in the third with a 467-foot two-run shot to right-center, the longest blast in Marlins Park history.

Christian Yelich added an RBI groundout in the sixth and Stanton went deep in the eighth as Miami improved to 4-3 versus Washington at home, compared to 0-6 on the road.

Haren was charged with five runs in three innings and has given up 12 runs in 5 2/3 frames over his last two starts. Adam LaRoche reached base twice for the Nationals, who had won their previous four games against the Marlins.
