Whitley, 19, sports a 3.60 ERA, 1.10 WHIP and 19:2 K:BB in 10 innings (three starts) with Low-A Quad Cities.

His outlandish 47.5 percent strikeout rate is due, in part, to him lasting just two innings while fanning six in his last outing, but this is still a pretty excellent start to the season for last year's 17th overall pick. Whitley has frontline upside, thanks to the potential for three plus or plus-plus pitches. As a 6-foot-7, 240-pound pitcher, he may take a little longer than the typical high-end pitching prospect to put it all together, but he could be worth the wait.
