​Tennessee baseball has added Clemson transfer Hayden Simmerson, a right-handed pitcher who will be a senior next season and is eligible for this year’s MLB draft, according to multiple reports on July 9. Simmerson, who was one of Clemson’s top relievers, posted a 1-2 record with a 3.62 ERA and four saves as a junior in 2026. He struck out 46 batters and walked 11 across 32.1 innings, recording a 0.90 WHIP during that season.
Before transferring to Clemson ahead of the 2026 campaign, Simmerson spent two years at Catawba, where he earned Division II All-American honors in 2025. Across his two seasons with the Indians, he went 6-5 with a 3.48 ERA, notching 23 saves and 146 strikeouts in 126.2 innings pitched.
Simmerson’s addition marks Tennessee’s 10th transfer and sixth pitcher this offseason. He joins a group that already includes Parker Detmers (Louisville), Jake McCoy (South Carolina), Ricky Ojeda (UC Irvine), Brody Trosclair (Northwestern State), and two-way player Braydon Kersey (Mercer). The Vols’ transfer activity has also brought in a mix of infielders, outfielders, and bullpen arms, reinforcing Tennessee’s roster depth as it retools for the upcoming season.
Other recent Tennessee transfers highlighted around the program include pitchers Nic Abraham (Virginia Tech) and Jax Bishop, infielders Ariel Antigua (Arizona) and Finley Bates (Jacksonville State), and numerous other contributors such as Chris Ramirez, Travis Sanders, and Braydon Krenzel, among others. The breadth of additions reflects Tennessee’s strategy of leveraging the transfer portal to accelerate program development and address immediate needs across multiple roles on the roster.
The Tennessee beat has followed Simmerson’s journey from Clemson to Knoxville, with observers noting his experience as a proven late-inning option who can deliver strikeouts and maintain a low WHIP. His continued development at Tennessee will be watched closely as the Vols anticipate a competitive run in the upcoming season, both in the SEC and on the national stage.

This hiring news comes amid Tennessee’s broader offseason movement, which has included a strong emphasis on balancing experienced arms with younger prospects to bolster depth in the bullpen and rotation. As Simmerson transitions to the Southeastern Conference, evaluators will be watching how his repertoire translates to the higher level of competition and how quickly he can contribute meaningful innings for the Vols. Tennessee’s coaching staff will likely emphasize leveraging his ability to pitch in high-leverage situations, while also ensuring he adapts to the pace and intensity of SEC play. The transfer window remains active, and further rosters moves could follow as teams finalize their spring rosters and prepare for the 2027 season.
