September is a special time of year in baseball, historically, as rosters expand and the contenders prepare for their playoff runs. For the non-contenders, the roster expansion means that fans often get to see a glimpse of the team’s future. For the 2019 Mariners and their fully-stocked farm system, this September has been full of fun moments with shiny, new toys.
