Jake Peavy from a stint on the disabled list, and it was a nice return for the right hander despite the results.

Clint Robinson hit a two-run home run off of Peavy in the bottom of the seventh inning, as the Washington Nationals defeated the San Francisco Giants 2-1 at Nationals Park.

Robinson playing in place of the injured Ryan Zimmerman is hitting .290 in 69 at-bats in his last 21 games after just 13 at bats in his career coming into the season.

The Robinson home run made a winner of Gio Gonzalez, as he allowed just one run on five in seven innings of work.

Buster Posey gave the Giants a 1-0 lead in the top of the seventh inning, as he took the first pitch from Gonzalez and put it into the seats.

Peavy went 6.1 innings, allowing two runs on just three hits, while walking four and striking out four in his first game after a stint on the disabled list.

Right-hander Tim Hudson was placed on the disabled list with a shoulder problem to make room for Peavy.
