For the first time since at least 2013, the most important developments in the Mariners organization will be in the minor leagues, not in the majors. This week we’ll be continuing our preview series introducing you to projected rosters for each of the minor league affiliates; so far we’ve covered the top two levels of the organization, the Triple-A Tacoma Rainiers and the Double-A Arkansas Travelers, both of which shape up to have some really exciting prospect talent. High-A Modesto might not have quite the snap of some of the other levels, but there are interesting role-players here, a few sleepers, and maybe even a star or two.
