Easton Cullison enters his third season on the USC Upstate baseball staff in 2027 and his second as a full-time assistant coach. A former Spartan infielder, Cullison joined the coaching staff as a student assistant for the 2025 season before earning a promotion to assistant coach ahead of the 2026 campaign.
In his first season as a full-time assistant coach in 2026, Cullison helped Upstate continue its historic run as the Spartans captured their second consecutive Big South Tournament Championship and advanced to the NCAA Tuscaloosa Regional. The appearance marked the second straight NCAA Tournament berth for the program after making its NCAA Division I Tournament debut the previous season.
The Spartans continued making history during the NCAA Tuscaloosa Regional, earning the first NCAA Tournament victory in program history with an 8-5 win over No. 2 seed Oklahoma State. The victory helped Upstate advance to the third day of regional play and capped another milestone season for the program.
Cullison began his coaching career as a student assistant at Upstate in 2025, working primarily with the Spartans' offense and infield defense while serving as the team's first base coach. He helped Upstate capture the first Big South regular-season and tournament championships in program history before earning the program's first NCAA Division I Tournament berth and competing in the NCAA Clemson Regional.
Under Cullison's assistance, the Upstate offense ranked among the top 30 nationally in 11 statistical categories during the 2025 season. The Spartans led the NCAA in sacrifice flies while ranking second nationally in hits and runs and third in scoring. Upstate finished the season with a .315 team batting average while producing 685 hits, 569 runs, 140 doubles and 101 home runs.
Prior to joining the coaching staff, Cullison spent four seasons as an infielder for the Spartans from 2021-24, establishing himself as one of the most successful base stealers of Upstate's Division I era. Across 145 career games and 111 starts, he posted a .281 career batting average while collecting 116 hits, 86 runs and 53 RBI.
Cullison concluded his playing career as the program's Division I era career record holder with 52 stolen bases. He also owns the Division I era single-season record with 25 stolen bases, a mark he established during his junior campaign in 2023.
His most productive offensive season came in 2023 as he appeared in 51 games and made 45 starts. Cullison hit .302 with a .404 on-base percentage and .384 slugging percentage, collecting 52 hits, 36 runs, 14 doubles and 25 RBI. He drew 23 walks and was hit by nine pitches while stealing a Division I era-record 25 bases in 30 attempts. Cullison recorded 12 multi-hit games, four multi-RBI games and ended the season on a 14-game reached-base streak.
Cullison helped the Spartans reach the Big South Tournament Championship Game for the first time in program history during the 2023 season. Upstate collected a then-program-record 38 overall victories and a program-best 21 conference victories for a non-40-game conference schedule. His speed helped an Upstate offense establish a program record with 110 stolen bases during the campaign.
