After Adams had a spectacular senior season for his varsity baseball team in the Atlanta area, the White Sox happily pounced on him with their second round selection in the 2014 draft. And after a terrific season for the AZL Sox that year, in which he struck out 59 batters while walking just four in 41 2/3 innings, it certainly looked like the sky was the limit for Adams.

Adams continued to post solid numbers with every new stop in the organization, but his stuff seemed to back up as his strikeout rates plummeted. In 2017 for the Birmingham Barons, he posted a 4.42 ERA and 1.38 WHIP over 152 2/3 innings by relinquishing 171 hits (.281 OBA) and 40 walks (6.1%) while fanning just 113 (17.2%). He again posted decent overall numbers with Birmingham and Charlotte for 2018, but with concerning peripherals: 3.79 ERA and 1.38 WHIP over 159 innings allowing 162 hits (.267 OBA) and 58 walks (8.6%) while fanning 95 (14.2%).

Adams’ 2019 just never got off the ground, due to a combination of ineffectiveness and injuries. Of course, the injuries caused many of the issues, but a combination of a lack of overpowering stuff and the live Triple-A ball didn’t help matters any. In five games (three starts, with his last outing on April 28), Adams posted an 8.00 ERA and 2.39 ERA over 18 innings as he allowed 35 hits (.412 OBA) and an unusually high eight walks (8.3%) with 10 strikeouts (10.4%). A back injury is what finished Adams’ season prematurely, and it’s hoped that he could return to Charlotte in 2020.

Adams, who was a former Top 10 prospect in the White Sox organization, did have 50 grades with his low-90s fastball and changeup, while he graded a bit better according to MLB Pipeline with his control (60) prior to his injury. He’s still just 23 years old, but it feels like his time as a prospect of note is long passed.

  1. Is he still around? He was once a #100 prospect in BA, and now he barely cracks the top 100 with us alone. I know he’s had injuries, so I hope he can bounce back in 2020 in AAA or somewhere for us.


    1. He barely pitched in 2019, and a big part of his top prospect status back then was that he was reportedly throwing 92-94 and peaking at 96 when he was drafted and it was presumed he would add a tick or two from there, but now he sits more like 88-90 and his control took a step back the last couple years. He’s one of the few high draft picks the White Sox used on a high school prospect this decade, which is why his long tenure in the farm system is so noticeable.
