Throw out the first pitch at a #Mariners game. A great perk of bringing a large group to Safeco Field is that you can throw out a first pitch before the game. Call (206) 346-4001 to speak to a representative or click the photo for more information.
Get an autograph from a #Mariners player. In addition to catching a player at a game, fans can also send letters to Safeco Field, PO Box 4100, Seattle, WA 98194 (sending items other than letters or pictures is discouraged).
