The game will be made up as part of a split doubleheader on Aug. 13, when Miami returns to Atlanta.
Braves right-hander Anibal Sanchez, who had been set to pitch Wednesday night, will have his start pushed back. Braves manager Brian Snitker said right-hander Mike Foltynewicz will start as scheduled when Atlanta opens a four-game series at the New York Mets on Thursday night.
Before the game was postponed, right-hander Kevin Gausman, acquired from the Baltimore Orioles before Tuesday's trade deadline, had been set to start on Friday. Snitker indicated he may shuffle his rotation plans after Thursday's game.
The Braves won the first two games of the series with Miami and entered Wednesday's schedule one-half game behind first-place Philadelphia in the NL East. Rain delayed the start of Tuesday night's game by 1 hour, 27 minutes.
