Two years after the Pittsburgh Pirates gave Mitch Keller a seven-figure bonus out of high school, Bowman included him in their 2016 Draft set. Keller established himself as a top prospect while pitching for the West Virginia Power in 2016. He had a 2.46 ERA and an 0.92 WHIP in 23 starts, with 131 strikeouts in 124.1 innings. He ended the year a level higher with the Bradenton Marauders, helping them to a Florida State League title. This is the year that Keller broke into top 100 prospect rankings. The card shows him in a full Pirates uniform, about to deliver a pitch.
