Happy almost MiLB Opening Day! While we always follow the minor leagues fairly closely here at the site, this year we’re particularly enthusiastic about some of the talent in the system and excited to watch the careers of these young Mariners progress. Below is a quick overview of the affiliates, in descending order, including players to watch and links to their schedules. If you for some reason don’t have the time or inclination to watch four minor league games a day, check here on Mondays for our minor-league roundup, where we’ll summarize the last series for each affiliate for you.
