11. Houck has been viewed for some time as a legit prospect due to his impressive fastball. He can touch upper 90s with the pitch and sits in the mid-90s, but the movement of the pitch and its sink is what makes it a truly special pitch. While that alone could get him notice, he has shown improvement in his offspeed stuff this spring, specifically his change. While his arm slot does bug some evaluators, he has a good frame and repeats his delivery well.. RHP. University of Missouri. Tanner Houck . 21. player
