Jose De Leon burst onto the prospect scene last year with an eye-popping strikeout total for high Class A Rancho Cucamonga of the heavy-hitting California League. Having slimmed down since the Dodgers picked him in the 24th round of the 2013 draft, he started throwing his fastball in the mid-90s and developed a breaking ball that genuinely baffled hitters. He kept piling up strikeouts after a midseason promotion to Double-A, but his home run rate there suggests he does still have some work to do. Because he's already 23, it wouldn't be surprising to see him get the call at some point this year, and the thinning of the Dodgers' rotation depth makes him a long-shot candidate this spring. For now, drafting him in mixed leagues would be too optimistic, but he has that kind of upside.
