Signed to a $700,000 contract with the White Sox on Jan. 15, 2023, Luis Reyes has slowly but steadily developed into one of
the more interesting young arms in the system. At 6´2´´and 190 pounds, Reyes noticeably added some strength since he first arrived in pro ball, and this translated to additional power on the mound. Unfortunately, Reyes missed all of 2026 after a lat injury in Spring Training put him under the knife.
Before injury, Reyes threw with a loose, easy arm action and repeated his delivery well. His fastball played in the low- to mid-90s but had touched 97 mph. The righty also threw a slider in the low 80s — which was by far his most-used pitch, thrown almost half the time. The 81-84 mph go-to slider had the makings of an actual out pitch. His other offerings were works-in-progress, but the foundation of a solid arsenal is in place.
At just 19 years old for all of the 2025 season, Reyes worked all year for the Kannapolis Cannon Ballers. The hurler showed signs of continued development despite a somewhat uneven season overall. After a tough April and May, Reyes was able to turn the corner in mid-summer. The righthander was named MiLB Pitcher of the Month in June, when he gave up only one earned run over 25 innings. Reyes posted a microscopic 0.36 ERA and a 0.720 WHIP in that span, highlighted by two seven-inning, complete-game shutouts. He understandably regressed a bit in July (5.59 ERA) before ending the season on a stronger note in August (3.60 ERA).
After underwhelming results in the DSL and Complex League in 2023 and 2024, 2025 was a step in the right direction for Reyes. He improved his command and averaged 9.10 K/9. Unfortunately, he never got the chance to build on that progress in 2026 due to that surgery in March to repair a lat injury.
Heading into 2027, the priority is getting healthy and back on the mound, almost certainly starting in the ACL and likely spending a good chunk of the season there. With his size, arm strength, athleticism and makeup, Reyes still offers the potential of a mid-rotation starter, but a lost year adds uncertainty to that projection. Once healthy, he can get back to refining his command and secondary pitches while rebuilding his workload. The upside remains intriguing. Now he needs the innings to keep developing it.
