Tacoma Rainiers Roster Projection

I’ve been at spring training for the last couple days and after the sixth inning when the regular players have been replaced, I’ve been repeatedly looking at Fan Graphs profiles at each of them. I’m trying to be a far better-informed fan of the 180 players that are part of the Mariners organization outside of the major league team. All of these players have worked for years to be as in the position of a professional ball players and they all deserve to have their stories told even if their chances of making the show are near zero. In this piece I want to provide a baseline knowledge for nearly every player in the organization: how they were acquired which team they’ll be playing for in 2022, contract status, best 2021 stat and whether they fit in as a prospect, farmhand or MLB depth.

For the Rainiers and Travelers roster projections there are more than twenty-eight players because of the influx of minor league signings that will surely be trimmed down in the post Cactus League roster shuffle. In addition, Billy Hamilton is the only player on a minor league contract not listed, as with expanded rosters it seems likely he will serve as pinch runner and defensive replacement for the first month of the season.
