Stephen Strasburg says his disagreement with Max Scherzer is within the "family" and tells reporters they're not in the "family." (0:16)

WASHINGTON -- The game between the Atlanta Braves and Washington Nationals has been postponed because of the threat of all-day rain.

The makeup date was not announced at the time of the postponement Saturday.

The series between the NL East rivals is scheduled to conclude Sunday with the All-Star pitching matchup of Mike Foltynewicz (7-5, 2.66) against Max Scherzer (12-5, 2.41). That game is to start 1:35 p.m., though rain is forecast.

Braves pitcher Sean Newcomb (8-5, 3.51 ERA) and the Nationals' Gio Gonzalez (6-6, 3.72) were Saturday's scheduled starting pitchers.

The Braves, battling Philadelphia for the division lead, beat Washington 8-5 on Friday. Washington fell to 48-49 with the loss and has dropped three of four games.

Scherzer, who started the All-Star game Tuesday night at Nationals Park, engaged in a heated spat with fellow starter Stephen Strasburg in the dugout during Friday night's defeat.
