As a starter at Bacone College, Tim Hill was very good in 24 starts (25 appearances) and tossed 157.0 innings while striking out 102 batters to the tune of 2.12 ERA. He landed into the laps of the Kansas City Royals in the 32nd round of the 2014 MLB Draft and they felt he would be better served as a bullpen arm.
His submarine delivery is not sustainable to make it in the big leagues as a starter for the next 15 years. Add to that his fastball tops out at 90 mph and he primarily just has two pitchers with the slider being the other.
