Nathan Kirby

Kirby was one of the top college pitching prospects in 2014, but medical issues resulted in him sliding to Milwaukee with the 40th pick in the 2015 draft. He pitched 12.2 innings in August for Low-A Wisconsin, but ended up needing Tommy John surgery in September, essentially ruling him out for all of 2016. For this reason, there is no need to target him in all but the deepest dynasty leagues, but this is not a player to forget about. Kirby has a plus fastball and plus slider when healthy, and if his changeup progresses he could become a No. 3 starter. If the elbow surgery proves to be a major developmental setback, and his command does not come all the way back, he has the stuff to make it as a late-inning reliever. Kirby should be on a strict innings limit in the lower levels when he returns in 2017, so while he is 22 years old, he may not reach the majors until around 2019 or 2020.
