WASHINGTON, DC (WHBL) - Gio Gonzalez became this season’s first 20-game winner, pitching the Washington Nationals to a 10-4 victory over Milwaukee on Saturday afternoon.  Gonzalez also became the first Washington pitcher to strike out 200 batters since Walter Johnson in 1916. Ryan Zimmerman and Ian Desmond pounded a pair of three-run homers in the fourth inning to help end the Brewers’ six-game winning streak. Milwaukee has fallen two and a half games behind St. Louis for a National League wild-card berth in the playoffs. The lefty Gonzalez went seven innings, allowing just three hits and two unearned runs. He is a Cy Young candidate with a 20-8 record and an earned run average of 2-point-84. Milwaukee starter Wily Peralta was knocked out in the third inning. The Brewers did manage to scored twice in the sixth, then Taylor Green hit a two-run homer in the ninth. Yovania Gallardo pitches for Milwaukee today, against Washington’s Chien-Ming Wang.  Coverage on WHBL begins at 12 Noon.
