Participating Mariners players and front office personnel will be announced at a later date. FanFest highlights include "Dugout Dialogue" chats with players, coaches and front-office members and player autograph sessions, and the chance for fans to run the bases, tour the Mariners' clubhouse, throw a pitch in the bullpen and play catch in the outfield.
