MIAMI -- Shortstop Adeiny Hechavarria drilled a three-run triple, and the Miami Marlins won their fifth straight game, defeating the Washington Nationals 6-2 on Sunday at Marlins Park.

Hechavarria extended his hitting streak to nine games and had his second consecutive three-RBI game as Miami (8-11) sent Washington (7-12) to its fifth straight loss.

Marlins right fielder Giancarlo Stanton also had a big game with two hits, including a 415-foot, run-scoring triple. Catcher J.T. Realmuto hit the third Marlins triple of the day.

Miami second baseman Dee Gordon, who leads the National League in hits, went 4-for-5 and is hitting .390.

The win went to right-hander Dan Haren (2-1), who started and allowed three hits, three walks and two runs in five innings.

Gio Gonzalez (1-2), a former 20-game winner and a native of Miami Dade County, took the loss. He struck out eight but allowed 10 hits and six runs in just five innings. The loss snapped Gonzalez's five-game win streak against his hometown team.

Washington opened the scoring in the second on right fielder Bryce Harper's leadoff homer, his fifth of the season.

Miami rallied in the fourth. Stanton singled, center fielder Marcell Ozuna walked, and left fielder Ichiro Suzuki hit an infield single to load the bases with two outs.

Washington should have gotten out of the inning right there because Stanton rounded too far off of third base and got caught in a rundown. But Nationals catcher Wilson Ramos botched the play, failing to throw to third. The next batter was Hechavarria, who cleared the bases with his triple to right-center.

Ramos hit a leadoff single in the fifth and came around to score on a single by center fielder Denard Span, cutting Washington's deficit to 3-2.

But the Marlins built their lead back up with two runs in the fifth on Stanton's RBI triple and a run-scoring single from Ozuna.

Miami made it 6-2 in the sixth when Realmuto tripled to left-center and scored on a Suzuki single.
