Minor League Development (2019–2023)
Gillispie made his professional debut with the Low-A Aberdeen IronBirds in 2019. He made 14 appearances and posted an impressive 1.77 earned run average with 21 strikeouts, demonstrating early promise as a pitcher capable of retiring professional hitters. The 2020 season was lost due to the cancellation of the minor league campaign because of the COVID-19 pandemic, denying him a full season of development that year.
He returned to Aberdeen in 2021, now classified as a High-A affiliate. That season, Gillispie worked primarily as a starting pitcher, appearing in 21 games with 12 starts. He compiled a 4-8 record with a 4.97 ERA and 78 strikeouts across those appearances. The following year in 2022, he returned to Aberdeen for a third consecutive season and showed significant improvement, posting an 8-5 record with a 3.79 ERA and 113 strikeouts over 25 appearances including 14 starts. His strikeout numbers demonstrated his ability to generate swings and misses at the Low-A level.
Gillispie received a promotion to Double-A in 2023, joining the Bowie Baysox. He appeared in 27 games with 14 starts, accumulating a 7-4 record and 3.89 ERA with 99 strikeouts across 115 and two-thirds innings pitched. He also recorded 2 saves that season, showcasing his versatility in different roles. His strong performance with Bowie earned him recognition within the Orioles organization and positioned him for an opportunity with another club.
Cleveland Guardians (2024)
On December 6, 2023, the Cleveland Guardians selected Gillispie from the Orioles in the minor league phase of the Rule 5 Draft. This transaction gave him an opportunity to continue his career within a new organization. He reported to Triple-A Columbus Clippers to begin the 2024 season, where he continued to refine his craft against more experienced hitters.
On August 4, 2024, the Guardians selected Gillispie to the 40-man roster and promoted him to the major leagues for the first time in his career. He made his MLB debut shortly thereafter, appearing in three games during his rookie campaign. In those three relief appearances covering eight innings, he posted an outstanding 2.25 ERA with eight strikeouts, demonstrating that his stuff could compete at the highest level. However, the Guardians designated Gillispie for assignment on November 19, 2024, and non-tendered him on November 22, making him a free agent.
Miami Marlins (2025)
On November 29, 2024, Gillispie signed a one-year major league contract with the Atlanta Braves organization.

Gillispie made the Marlins Opening Day roster and joined their starting rotation. He made six starts for Miami, but struggled with his command and results during this stretch. Across 26 innings of work, he went 0-3 with an 8.65 ERA and 23 strikeouts. The Marlins designated Gillispie for assignment following the promotion of Robinson Pina on June 19, 2025, ending his tenure with the club.
Minnesota Twins (2025)
On June 23, 2025, the Minnesota Twins claimed Gillispie off waivers. He reported to the Triple-A St. Paul Saints, where he made four appearances including three starts. Unfortunately, he struggled significantly in his stint with Minnesota’s top affiliate, posting a 1-1 record and a 14.49 ERA with just six strikeouts across 13 and two-thirds innings. The Twins designated Gillispie for assignment on July 28, 2025. He cleared waivers and was sent outright to Triple-A St. Paul on July 30, where he finished the season. Following the conclusion of the 2025 campaign, Gillispie elected free agency on November 6, 2025.
