The Nationals' pitching staff has yet to give up a run this season, Wednesday's shutout following a 2-0 blanking of the Marlins in their season opener Monday.
Gonzalez gave up two hits over six innings and struck out five. He also delivered Washington's first run with a homer in the fifth. Rafael Soriano completed the work of the bullpen, working the ninth to pick up his second save in as many appearances.
Kevin Slowey took the loss, giving up the Gonzalez homer and three other hits over 5 1/3.
