There's a shot that Starling will be a September call-up next season. His defense is said to be major league quality right now. His speed is also a premium skill. His bat, while improved, is not there yet. The Royals, however, have carried guys with very similar skill sets the past several seasons in Dyson and Orlando. Since both Dyson and Orlando are likely to still be around next year, Starling will start in AA, with a promotion to Omaha a real possibility if he continues to develop offensively.
But in September, he could definitely add something to the big league club.
