As a freshman in 2016 for the Gators, Kowar appeared in 12 games, with a 3–0 record, 3.37 ERA, and 44 strikeouts in innings pitched. His season ended in May due to a collapsed lung. In 2017, he went 12–1, tying Florida's best single-season record in school history, along with posting a 4.08 ERA with 84 strikeouts in 19 games. Kowar earned the save in the College World Series championship game, pitching scoreless innings in his only relief appearance on the season, clinching Florida's 2017 national title. In 2018, as a junior, Kowar was named to the All-SEC second team. He had a 10–5 record and a 3.04 ERA in 18 starts.

Kowar did not play in a game in 2020 due to the cancellation of the minor league season because of the COVID-19 pandemic. He trained at the team's alternate site during the abbreviated MLB season. Kowar began the 2021 season with the Omaha Storm Chasers of the Triple-A Triple-A East. In six games to begin the year, Kowar had a 5–0 record and 0.85 ERA with 41 strikeouts in innings pitched.

He was officially selected to the active roster on June 7. In his debut, Kowar gave up four earned runs, allowed three hits, walked two batters, and threw three wild pitches before he was removed from the game in the first inning, getting only two outs. In 9 appearances (8 starts) during his rookie campaign, Kowar posted a ghastly 0–6 record and 11.27 ERA with 29 strikeouts in innings pitched. He received the Paul Splittorff Pitcher of the Year award from the Royals, given to the franchise's best minor league pitcher. In 2022, Kowar struggled in both Omaha and Kansas City. Starting 20 games for the Storm Chasers, he worked to a 4–10 record and 6.16 ERA with 88 strikeouts in innings pitched. He limped to a 9.77 ERA with 17 strikeouts in innings of work across 7 relief appearances for the Royals.
