If you made it out to the game last night and still are in possession of your ticket, there is good news.
Per club policy for rain delays extending 90 minutes or more, any fan holding a ticket for Tuesday's game can exchange that ticket for $1 for any remaining Monday through Thursday regular-season Marlins home game.
And last night's rain delay was definitely more than 90 minutes. So your two choices are the Atlanta series, September 1-3, or the games against the Astros, September 16-18. Personally, I would go with the Atlanta series, but the decision is yours to make.
