Gonzalez has been spectacular in his first year as a National, posting a 3.23 ERA and 161 strikeouts. He will go for a league-leading 17th win tonight.
But challenging Gonzalez and the Nationals will be two-time Cy Young Award winner Roy Halladay. "Doc" has had his worst season in years, but things have looked slightly better of late, as he's won three of his last four starts.
The Nationals haven't had a Cy Young or 17-game winner since Pedro Martinez did both for the Montreal Expos in 1997.
Meanwhile, the Nationals' lead in the National League East has shrunk a bit of late. They currently lead the Atlanta Braves by 6.5 games.
Saturday's game starts at 7:05 ET, and can be found on MASN.
