Washington, DC (Sports Network) - A throwing gaffe on a potential inning- ending double-play grounder off the bat of Adam LaRoche plated Bryce Harper with the winning run, as Washington rallied to beat San Francisco, 6-5, and sweep a three-game series.

Down 5-4 in their last at-bat against Santiago Casilla (2-4), pinch-hitter Tyler Moore led off with a double, then moved to third as Casilla couldn't pick up a Steve Lombardozzi sacrifice bunt try. Harper then bounced a single through the right side to tie the game and leave runners at the corners. Ryan Zimmerman was given an intentional walk to load the bases, then a Michael Morse grounder to second turned into a force at home.

LaRoche followed with a ball to the right side, and the first out was recorded at second by Giants shortstop Brandon Crawford off a throw from Ryan Theriot. But Crawford's flip to first bounced in front of Brandon Belt and glanced off his glove, allowing the deciding run to score.

It made a winner of Tyler Clippard (2-2), who turned in a scoreless top of the ninth.
