The Seattle Mariners are celebrating Autism Awareness Day on Sunday, April 15th at Safeco Field! Attendees will have the opportunity to claim a free Autism Awareness Day t-shirt with their ticket purchase. Seven dollars of every ticket sold through their website will benefit Autism Speaks. The Mariners will also have a sensory-sensitive quiet area at the Ellis Pavilion for families on the day of the game. First pitch is at 1pm against the Oakland Athletics—so go root, root, root for the home team! Click here to learn more about this event!
