Gavin Guidry’s Path from LSU Stars to Undrafted Prospect

Early Beginnings in Lake Charles

Born and raised in Lake Charles, Louisiana, Guidry attended Alfred M. Barbe High School, a program that has produced another notable talent linked to the Mets. Growing up in the same hometown as a fellow Gavin who also wore a Mets jersey, his early exposure to competitive baseball set the stage for a remarkable high‑school career.

During his senior year, Guidry earned Louisiana’s 2022 Gatorade Player of the Year honor while hitting .422 with five home runs. On the mound he posted a blistering 0.16 ERA over 45 innings, striking out 83 batters. His dual threat at the plate and on the hill helped Barbe capture district titles in 2019, 2021 and 2022, plus a national championship in 2021.

Choosing College Over the Draft

When the 2022 MLB Draft arrived, Guidry was marked as the state’s top high‑school prospect and a top prep player in the class. Rather than accept the flood of professional offers, he opted to honor his commitment to Louisiana State University, retaining draft eligibility for a possible sophomore selection.

At LSU, freshman coach Josh Jordan used him as a two‑way contributor, logging 23 relief appearances and 12 defensive games at second base and shortstop in 2023. He posted a 3.77 ERA with 42 strikeouts across 28.2 innings and recorded three saves, though his offensive numbers were modest (.143 batting average). Despite the modest bat, his bullpen work signaled the potential of a future reliever.

College Rise and Back‑Trouble Setback

Guidry’s sophomore season in 2024 showed continued growth, with a 2.59 ERA and 36 strikeouts in 24.1 innings, plus three more saves. However, he saw limited action at the plate, appearing in only one game and collecting a double. The 2024 MLB Draft passed without his name being called.

After the season, chronic lower‑back pain emerged, eventually diagnosed as a herniated L4‑L5 disk. Surgery ended his 2025 campaign, and he watched LSU capture its second national title in three years from the sidelines. Undrafted again in 2025, he spent the following winter rehabbing and rebuilding his strength.

Comeback Year and Professional Ambitions

Guidry returned for the 2026 redshirt junior season, posting a 6.39 ERA with 59 strikeouts in 43.2 innings and one save. Sensing the need for additional development, he joined the Chatham Anglers of the Cape Cod Baseball League after the college season. He remains draft‑eligible and has expressed a desire to re‑join LSU in pursuit of another championship.

Physically, the 6‑foot‑2, 185‑pound right‑hander features a high‑three‑quarter arm slot and a medium arm action, delivering clean, deliberate mechanics. His repertoire includes a four‑seam fastball, cutter, slider and curveball, giving him multiple weapons for relief work.

Pitching Repetto and Velocity Concerns

Guidry’s fastball sits in the low‑90s after surgery, a notch below the mid‑90s range he posted before the back issue. He compensates with above‑average vertical break—up to 20 inches—thanks to spin and a high release point. His slider, a mid‑80s pitch with tight gyroscopic movement, serves as the primary strikeout instrument and often tunnels with the fastball.

The cutter, hovering in the high‑80s, provides horizontal hop and acts as a transition pitch, while the curveball (mid‑to‑high‑70s) functions mainly as a sequence‑buster. Despite the slider’s success, Guidry can become over‑dependent on it, occasionally throwing it more often than his fastball.

Home‑Run Bumps and Statistical Outlook

In 2026, Guidry allowed ten home runs in 43.2 innings, nearly double the six he surrendered in the combined 2023‑2024 seasons. His fly‑ball rate dropped to 44.5% from roughly 49.4% earlier, but the home‑run per fly‑ball percentage spiked to 20.4% from about 10.5%. Batters posted a .229/.318/.434 slash against him with a .280 BABIP, a noticeable shift from the .165/.317/.247 line in his sophomore year.

The spike in home runs appears anomalous given the lower fly‑ball rate, and observers expect the numbers to normalize once his pre‑injury fastball velocity returns. If velocity rebounds, Guidry’s mix of breaking pitches and above‑average vertical break could make him an attractive relief target for MLB scouts.
