Pitching for Casa Grande Union H.S. (Ariz.), Gil Luna Jr. was named in 2016 a Louisville Slugger All-American. Supposedly it had something to do with posting a 1.16 ERA with 138 strikeouts as a junior. Not only did Luna win that award as a junior, he had a fantastic senior season as well, which enticed the prestigious University of Arizona to lure him into its program.

Luna struggled, however, in first three years as a Wildcat with ERAs of 5.32, 10.31 and 9.15. However, something clicked for him during his senior season in 2021. In 14 appearances totaling 21 1⁄3 innings, Luna posted a nifty 1.69 ERA and 1.13 WHIP by ceding just 13 hits (.178 OBA) and 11 walks (12.8%) while striking out 31 (36.1%). Based upon his potential and success that senior year, the White Sox selected him in the ninth round of the 2021 draft.

Combined with the ACL Sox and Kannapolis in 2021, Luna posted an exceptional 0.00 ERA and 0.72 WHIP over 10 relief appearances. Spanning a combined 15 1⁄3 innings, he relinquished just five hits (.106 OBA) and six walks (11.3%) while striking out 24 (45.3%): totally amazing stuff. While Luna’s walk rate was high, it was a far cry from his collegiate rate of 19.9%. It’s fair to assume coaches can live with a little higher walk rate if Luna can somehow maintain those high K rates.

After a promising mini-rookie season that caught everyone’s attention, 2022 was a major disappointment for Luna, both from a performance and health standpoint. While details on his injury aren’t known, Luna was active for just six weeks between Winston-Salem and a rehab stint in Arizona before getting 60-day shelved July 6 or later. A 60-day IL stint perhaps might be less dire/strategic in the minors that with the White Sox 40-man, but it’s not anywhere you want to find yourself.

Luna’s primary offerings are a fastball and curveball, and the MLB Network panel specifically cited him on Draft Day as possessing good arm strength and good movement on his 12-6 curveball. He may own the best stuff among southpaw relievers in the system, but the White Sox could give him more time to work on keeping the ball down, as his ground ball rate in 2021 hovered near 30%.

We don’t know enough about Luna’s injury to imagine what his 2023 projects to be, but if healthy he will get another crack at High-A, potentially getting back on the fast track up the system ladder given a dearth of southpaw relievers.
