Bruihl began the 2019 season with the High–A Rancho Cucamonga Quakes before being reassigned to the Single–A Great Lakes Loons.

The Dodgers selected Bruihl's contract and promoted him the Major League roster on August 8, 2021.

 In 2022, Bruihl split the season between the majors and the minors. He pitched in 25 games for Oklahoma City with a 3–1 record and 3.56 ERA and in 24 games for Los Angeles, with a 1–1 record and 3.80 ERA. On September 18, he picked up his first career save against the San Francisco Giants. Bruihl was optioned to Triple-A Oklahoma City to begin the 2023 season.
