Adcock will be playing in his fifth season of professional baseball and his first in Sioux City. 

An intimidating figure on the mound, the 2021 season will be Adcock’s first season in independent baseball after spending the last four in the Houston Astros organization. 

Houston drafted Adcock in the fourth round of the 2016 MLB Draft out of the University of Michigan. Pitching for the Maize and Blue, the lefty enjoyed a stellar career in which he went 24-13 making him the sixth most winningest pitcher in Michigan history. He also finished his collegiate career ranked sixth in school history in strikeouts with 256. 

Overall in his time at Ann Arbor, he held a 3.09 ERA through 60 games, 35 starts, and 221.2 innings. He flashed elite strikeout potential during those three seasons with a career 10.4 K/9 while also finishing inside the top ten in the Big Ten Conference in punch outs.

After an injury cut Adcock’s first professional season short, he bounced back in 2017 splitting time between Class-A, Quad Cities and High-A, Buies Creek. Between the two stops he put together a 5-4 record with a 3.93 ERA over 25 games, 18 starts. In 107.2 innings of work he racked up 117 strikeouts. That amount of punch outs equaled out to a 9.8 K/9. This was anchored by a 14.1 K/9 thanks to his incredible 37 strikeouts over 23.2 innings of work for Quad Cities. 

Staying in High-A, Buies Creek to begin the 2018 season, Adcock picked up where he left off and then some. He was named a Carolina League Mid-Season All Star which helped earn his promotion to Double-A, Corpus Christi. Overall in 2018, Adcock went 9-5 with a sparkling 2.89 ERA and struck out 95 over 106 innings and 25 games. 

The Michigan native, did not play in 2020 leaving 2019 as the last time he pitched before he eventually climbs the bump in Sioux City. He spent the 2019 season in Double-A appearing in 23 games, making 19 starts striking out 87 batters in 87.1 innings. 

In four seasons with the Astros, the 25 year old went a combined 16-17 in 76 games, 54 starts with a 4.45 ERA striking out 305 batters in 305.1 innings.
