The game was not initially scheduled to be aired, but the station decided to pick it up with Arizona lefty Patrick Corbin going for a perfect 10-0 start to the year, opposite Washington's Stephen Strasburg.
Steve Berthiaume and Bob Brenly will call the game, which begins at 1:05 p.m. MST.
"We know D-backs fans will want to see this game featuring two of the best pitchers in baseball," FOX Sports Arizona general manager Brian Hogan said in a statement.
