WASHINGTON, July 10 (UPI) -- Aaron Rowand touched off a four-run seventh with a solo homer Saturday, helping rally San Francisco past Washington 10-5.
The Giants won for the fifth time in six games.
Washington had a 5-4 lead going into the seventh, but Rowand tied it with his eighth homer.
Freddy Sanchez and Aubrey Huff then drew walks off losing pitcher Tyler Clippard (8-6) and Buster Posey put the Nationals in front with a single that scored Sanchez. Juan Uribe followed with a double that brought in both Huff and Posey.
Posey had four hits for the second time in four games and has hit six of his seven homers during San Francisco's current 11-game road trip. Over the last 10 days, Posey has batted .513 with 13 RBI.
Santiago Casilla (2-2), the third of six San Francisco pitchers, got the win by recording the last two outs of the sixth inning.
