Guyette, a rising senior, produced a 5.56 ERA in 16 appearances (15 starts) with the Wildcats in 2026. He tallied double-digit strikeouts in three starts last season, including 13 punchouts in a complete game victory over the Cincinnati Bearcats on May 10.

"[Guyette] went to training camp with the U.S. collegiate national team last summer," MLB Draft analyst Jim Callis said on MLB's live stream. "What stands out with him is the East-West contrast on his sinker and slider. He's got a 92-94 MPH sinker that breaks [arm side], a low 80s slider that breaks [glove side]... has also got a fading changeup that keeps guys off balance."

Guyette was an All-Big 12 Team Honorable Mention in 2025, when he operated exclusively as a reliever. As a starter in 2026, he racked up 105 strikeouts in 79 1/3 innings.
