Crochet was selected 11th overall in the 2020 draft in June. He's the first player from this summer's draft to get the call to the bigs.
Crochet is viewed as a starting pitcher in the long term but will come out of the bullpen during his initial stint with the White Sox, according to Scott Merkin of MLB.com.
The 21-year-old southpaw spent three years at Tennessee, though he only made one start in 2020 due to the coronavirus pandemic. He went 10-9 with a 4.64 ERA, 1.40 WHIP, and 149 strikeouts in 132 innings during his college career.
Crochet features a fastball that touches 101 mph and also throws an above-average changeup, and a solid slider, according to MLB Pipeline's scouting report.
