Gasser transferred to San Joaquin Delta College after his freshman year. In his only season with the Mustangs, he went 14-0 with a 2.38 ERA and 139 strikeouts in 102 innings pitched over 18 appearances with 17 starts.

Professional career San Diego Padres The San Diego Padres selected Gasser with the 71st overall pick in the 2021 Major League Baseball draft. He was assigned to the Rookie-level Arizona Complex League Padres to start his professional career, where he made one appearance before being promoted to the Lake Elsinore Storm of Low-A West.

Gasser began the 2022 season with the High-A Fort Wayne TinCaps and then pitched as well for the Biloxi Shuckers and the Nashville Sounds, posting a collective 7-12 record and 3.94 ERA with 172 strikeouts in 137 innings pitched across 27 starts.

He made his first MLB start the same day and didn't give up a run across six innings, allowing just two hits, no walks, and striking out four. The Milwaukee Journal-Sentinel called the performance "a Brewers major-league debut for the ages." He continued to have one of the best beginnings to a pitching career in franchise history, becoming the third Brewer since 1984 (along with Brandon Woodruff and Freddy Peralta) to record an ERA below 2.00 in his first four career starts. On June 20, it was announced that Gasser would require season–ending surgery to repair the ulnar collateral ligament in his pitching elbow.
