It can be tricky to track down details on Mason Miller—the baseball player. No, not the pitcher with the microscopic ERA since joining his new team earlier this season. And no, not the flamethrowing reliever who landed with the Padres at the trade deadline. This Mason Miller is the Kansas City Royals’ own: a 23-year-old southpaw carving up hitters with High-A Quad Cities.
Kansas City’s pitching pipeline has been filling up box scores and prospect chatter all season, but turning arms like Mason Miller into MLB contributors will be the true test of its viability.
