How difficult is it to make the major leagues?
The Seattle Mariners began their affiliation with Everett of the Northwest League 18 years ago, becoming the AquaSox in 1995. The Northwest League is a short-season single-A league, meaning there are four minor-league levels between Everett and the majors (low-A, high-A, double-A, triple-A). Most of the players who appear for the Sox are just at the beginning of their professional careers.
But most of them are also nearing the end of their professional careers. An average of 40 players came through Everett each season since the Sox began play. Of the estimated 720 who have donned the AquaSox uniform (not counting those on rehabilitation assignments), a grand total of 18 were on major-league rosters to begin the season. That’s fewer than one major-league roster.
Those who made the cut at the beginning of this season:
