 When the Yankees traded Justice Sheffield to the Mariners last month, MLB.com moved Garrett Whitlock into 10th place on its list of the organization's top prospects. The 22-year-old right-hander has gotten his professional career off to a terrific start. An 18th round draft pick out of the University of Alabama Birmingham in 2017, Whitlock received a taste of rookie ball right after he signed. Then he pitched for three different teams in 2018. He spent most of the season with high-eight Tampa, although he did reach double-eight for the first time, making a couple of appearances with Trenton. All told last year, Whitlock posted an ERA of 186 to a little more than 120 minor league innings while striking out a shade over nine batters per nine. He says his best pitch is his fastball, which lives in the mid-90s, and one of his main areas of focus last season was working on his breaking ball. Throw in a sinker plus a changeup and you've got a recipe for a pitcher to look out for in years to come. Considering that he stands at six foot five, Whitlock might be hard to miss.
