The Cubs and Braves avoided rain delays and/or postponements for the first two games of their series in Atlanta, but Thursday night’s game didn’t have the same luck:
The teams have no common off days remaining that wouldn’t break the 20-consecutive-day rule, except September 13. The problem with that: it’s in the middle of a Cubs homestand, and unlikely that they’d agree to fly to Atlanta for one game in that circumstance.
I haven’t checked the teams’ schedules for this, but they could try an unusual way of making up this game, and that would be to have the Cubs go to Atlanta on a day when they’re off, but the Braves aren’t, and thus the Braves would play a split doubleheader against two different teams.
