HNA/O'Dea Night at the Mariners
Holy Names - Student Life
Get ready to cheer on the Mariners with your community! Holy Names Academy and O’Dea High School have teamed up to bring you an unforgettable night of baseball. Join us on Wednesday, August 5, at 6:40 p.m. at T-Mobile Park as the Mariners go up against the Detroit Tigers.
Tickets are in the 100 level and are only $26 per person. Once purchased, tickets will be emailed closer to the game day. Please note that while this event is a community gathering, it is not a school-supervised function. We encourage families to enjoy the game together, taking this as an opportunity to supervise and bond with their own children.
Tickets are available for purchase here until July 15.
Purchase your tickets early, and don't miss out on this chance to watch a great game and build lasting memories with our community.
