There are basically two types of cancellations of baseball games due to adverse weather conditions:
Game in progress postponed: If this occurs while you are at the ballpark, keep your ticket stub and redeem it at the ticket office for a future game subject to availability and excluding special events. Please be advised, this transaction does not have to take place on the day the game is postponed. By New York-Penn League rules, five innings (or four and a half innings if the home team is leading the game) constitutes a complete game and no ticket refunds or rain checks will be issued. In the event a double header is postponed after five innings of game one have been completed, it will be considered a complete game. No refunds or rain checks will be issued.
Game postponed before gates open: If this occurs, keep your whole ticket and exchange it at the ticket office for a future game (within that season) of your choice, subject to availability and excluding special events.
