As a season ticket holder I can exchange tickets via the Season Ticket Exchange. Tickets need to be exchanged at least 2 weeks in advance. Most of the tickets will be in the View Level. I have 4 tickets to exchange this time.
The exchange tickets are "complimentary" with the face value of $0 and cannot be exchanged for a rain check. So if they cancel or suspend the game you are out of luck for the make-up game.
The following games are available:
Friday July 16 - 7:10vs. Colorado Rockies
Friday July 30 - 7:10 vs. Atlanta Braves
Sunday Aug. 1 - 1:10 vs. Atlanta Braves
Monday Aug. 9 - 7:10 vs. St. Louis Cardinals
Friday Aug. 13 - 7:10 vs. Florida Marlins
Tuesday Aug. 31 - 7:10 vs. Milwaukee Brewers
Wednesday Sept. 1 - 7:10 vs. Milwaukee Brewers
Friday Sept. 10 - 7:10 vs. Pittsburgh Pirates
Sunday Sept. 12 - 1:10 vs. Pittsburgh Pirates
Monday Sept. 13 - 7:10 vs. Arizona Diamondbacks
Friday Oct. 1 - 7:10 vs. Milwaukee Brewers
