"Our at-bats have been pretty good," Marlins manager Don Mattingly said. "There were a lot of guys that had quality at-bats. Ozuna's at-bats were good today."
Wilmer Difo had an RBI triple in the fifth inning to get Washington on the board, and Michael Taylor had two singles.

The Marlins did their damage early off Nationals right-hander Erick Fedde, Washington's No. 2-ranked prospect, according to MLBPipeline.com, who worked just 1 2/3 innings and gave up five runs. Fedde was lifted after Ozuna's two-out homer in the second inning and 51 pitches.
"I think I just kind of let the game speed up," Fedde said. "My fastball command was bad, and that just kind of led to the hitters staying off of everything else."
Marlins right-hander Scott Copeland, who is expected to open the season at Triple-A New Orleans, tossed three scoreless innings, giving up a hit and a walk and striking out one. It was his second straight start with three scoreless innings.
The Marlins manufactured two runs in the first inning. Dee Gordon led off with a drag-bunt single, and he swiped second for his first stolen base of the spring. Derek Dietrich had a sacrifice fly to put Miami on the board, and Ichiro Suzuki added a sacrifice fly to left.
