Indications are it will be either Friday, Sept. 26, or Saturday, Sept. 27, as part of a day-night doubleheader.
What the Marlins do know is the game on Tuesday night was called pretty early. The Nationals announced the postponement around 7:15 p.m. ET. But about an hour later, the rain had stopped, and the tarp was off the field. It didn't rain the rest of the night.
"I think it seemed early to call it," Redmond said. "But that's their call and there's not a whole lot we can do about it, just be ready to play [Wednesday]."
The home team makes the call on when the game starts. Once it does, then the game falls under the jurisdiction of the umpires.
Redmond joked that he had a nice walk around town on Tuesday night.
"I did," he said. "I didn't even need an umbrella."
The Nationals right now have several regulars on the disabled list, including Bryce Harper and Ryan Zimmerman. And the starting pitcher set for Tuesday was Blake Treinen, who was filling in for Gio Gonzalez, who is on the disabled list.
Miami had to reshuffle its rotation due to the rainout. Henderson Alvarez was set to start on Tuesday, and he was pushed back to Wednesday. Jordan Zimmermann, meanwhile, remained on schedule to throw, while Treinen has now been skipped.
"It was nasty at the time they made a decision, and that's it," Redmond said. "We'll play when they tell us to play, that's all we can do."
