Uggla's heroics gave him seven RBI in two games. He had five RBI and a grand slam in an 11-0 rout Saturday night.

The win was Florida's seventh in a row overall and their second straight three-game sweep at Nationals Park this season.

Uggla's 11th homer of the season capped a three-run outburst against Washington reliever and losing pitcher Luis Ayala (1-3) in the top of the eighth inning, when Florida erased a 4-2 deficit. He scored three times in the game.

Earlier in the inning, Jeremy Hermida's two-run blast tied the contest 4-4. Hermida, like Uggla, had two hits, and Wes Helms added a first inning sacrifice fly.

The winner was reliever Logan Kensing (2-0). Kevin Gregg earned his seventh save.

Washington got a solo homer from Aaron Boone in the second, a two-run shot from Ronny Belliard in the third and Boone's RBI triple in the third.
