WASHINGTON -- Giancarlo Stanton hit his NL-leading 15th home run and also doubled and singled in his latest power performance at Nationals Park, leading the Miami Marlins over Washington 3-2 Monday.
Stanton doubled and scored in the first inning, then launched a long two-run homer in the third.
Stanton is hitting .333 (43 for 129) with 14 home runs and 27 RBIs in Washington since his career began in 2010. He has homered at Nationals Park more than any other visiting player during that time.
The Marlins improved to 7-17 on the road; they're 20-8 at home.
Nathan Eovaldi (4-2) pitched 6 1-3 innings, giving up two runs and three hits. Steve Cishek worked the ninth for his 11th save.
Adam LaRoche homered for the Nationals, who had won 12 of their last 13 against Miami at home. Tanner Roark (3-3) went seven innings.
Eovaldi earned his first road win since Sept. 1, 2013. He has won consecutive starts for the first time in his career.
Washington trailed 3-0 and had only one hit before Jayson Werth singled with one out in the sixth. LaRoche, in his second game back from the disabled list, homered into the second deck in right to cut the deficit to 3-2.
Eovaldi left after hitting Nate McLouth with one out in the seventh. Mike Dunn retired pinch-hitter Tyler Moore and Denard Span, reliever A.J. Ramos pitched a perfect eighth.
The Marlins got to Roark for a two-out run in the first when Stanton doubled to right just beyond the reach of Werth and scored on Casey McGehee's single. McGehee is hitting .434 (23 for 53) with runners in scoring position.
Stanton and the Marlins struck again with two outs in the third. After Derek Dietrich was hit by a pitch, Stanton launched the first offering he saw to straightaway centre, with the ball bouncing high off a wall beyond the wall.
Miami had a chance for more in the sixth when McGehee doubled with one out, but he was picked off second by Roark.
