If you had tickets to last night's game, you are eligible to take advantage of the Marlins rain delay ticket policy. And from my understanding it doesn't matter even if you stayed from the whole game. The opportunity is still available to you.
Starting today, tickets can be exchanged at the Dolphin Stadium Marlins advance-sale ticket windows located at Gate G. Window hours are Monday-Friday, 8:30 a.m.-5:30 p.m. and Saturdays 10 a.m.-4 p.m.
Your choices are: go to the game tonight or wait until the final six game home stand which will start on Sept. 26.
