Mitchell earned an early-season promotion to Double-A in 2016. He was selected in the 13th round of the 2013 draft by the Reds out of Mississippi State. Mitchell works with a fastball in the mid-90s, but also has a devastating curve that complements it well. With those pitches, high K/9 numbers have followed, posting a career total of just under eight. However, command issues have haunted Mitchell in the past and have crept up at times in his pro career, but not as much in the past couple seasons.
