As a senior in 2019, he did not allow an earned run and struck out 106 batters over 60+2⁄3 innings.[1] Although he was scouted by major league teams, he went unselected in the 2019 Major League Baseball draft and enrolled at the University of Miami to play college baseball.[2]

As a freshman at Miami in 2020, Palmquist went 1–0 with a 2.31 ERA and 15 strikeouts over 11+2⁄3 innings before the season was cancelled due to the COVID-19 pandemic. As a redshirt freshman in 2021, Palmquist was named Miami's closer.[3] He made 25 appearances in which he went 1–1 with a 2.22 ERA, 75 strikeouts, and 14 saves over 44+2⁄3 innings.[4] His 14 saves were third best in college baseball.[5] He was named to the USA Baseball National Collegiate Team after the season.[6] For the 2022 season, Palmquist moved into the starting rotation.[7][8] Over 16 starts, he went 9–4 with a 3.54 ERA and 118 strikeouts over 84 innings. Following the season's end, he traveled to San Diego where he participated in the Draft Combine.[9]
