With the Mariners farm system healthier than it’s been in years, we have found it necessary to update our prospect rankings mid-season to account for players acquired in the MLB Rule 4 draft, those signed internationally, and players already in the system who have progressed (or, more worryingly, regressed). We’re also taking this opportunity to make some changes to the way we rank prospects; we’re doing away with a numbered list and instead will be presenting the prospects this week in six tiers, similar to John Sickels’ letter grade system or FanGraphs’ FV system, in order to both better reflect the 20-80 scouting scale and not rank prospects relative to each other, which seems both like poor methodology and like something that would tick farm director Andy McKay off (who are we kidding, any kind of prospect ranking system ticks Andy “Everyone’s A Prospect” McKay off).
