Yohemy Nolasco is a Dominican native who signed with the White Sox on Jan. 9, 2020 — right in the face of the pandemic. Getting his feet finally wet in 2021, in 13 games (seven starts) in the DSL Nolasco posted a 5.32 ERA and 1.48 WHIP by allowing 26 hits (.271 OBA) and nine walks (3.42 BB/9) while fanning 19 (7.23 K/9). While he was sharp in July with a 3.52 ERA and 1.30 WHIP in five outings, he only posted two outings in August, which indicates he may have been injured. September was easily Nolasco’s worst month, as he posted a 6.59 ERA and 1.61 WHIP over six outings.
Just turning 19 and with fewer than 25 professional innings under his belt, Nolasco nonetheless got an aggressive assignment in the ACL in 2022, and faltered in his 34 2⁄3 innings. His walks were at a low number overall (8.4%), but when that is coupled with a 16.9% K-rate, it loses luster.
Not much is known about Nolasco’s repertoire. His near-47% ground ball rate indicates he may possess a sinker or some other offering that has sinking action. At least in the DSL, he fared far better versus lefties (.194 OBA) than righties (.317), which may indicate he offers a plus changeup. His strikeout total is fairly low, which may be attributed to a fastball with little oomph — not surprising for someone of his size. With his height, he’s a projectable righty; if he can another 15-20 pounds of muscle, he would be expected to easily add another 4-5 mph on his fastball.

Nolasco only has 50 professional innings under his belt and next year is his true age-19 season, so Nolasco seemingly will be back in the ACL, with a late-season shot at Kannapolis.
