He made his major league debut on August 4, 2020, with the Seattle Mariners against the Los Angeles Angels.

Early Life and Background
Gerber grew up in Minnesota and graduated from Wayzata High School in Plymouth in 2015. During his high school years, he developed his skills as a pitcher, though he went undrafted in the 2015 Major League Baseball Draft following graduation. Rather than pursuing professional baseball immediately, Gerber chose to continue his athletic and academic career at the collegiate level.
After high school, Gerber enrolled at the University of Illinois where he played college baseball for the Fighting Illini. His decision to attend Illinois proved formative, as he refined his craft under collegiate competition while establishing himself as a reliable relief pitcher who would eventually tie a school single-season record for saves.
Path to Professional Baseball
Gerber arrived at the University of Illinois as a freshman in 2016 and saw limited action, pitching just six innings with a 7.50 ERA. He showed improvement during his sophomore season in 2017, posting a 2-1 record with a 4.36 ERA across 33 relief innings while striking out 43 batters. That same summer, Gerber gained additional experience playing for the Mankato MoonDogs of the Northwoods League, a prestigious collegiate summer baseball circuit.
His breakthrough came during his junior year at Illinois in 2018. Gerber delivered an outstanding season, recording a 1-1 record with a 3.14 ERA in 28 and two-thirds innings of relief work. Most impressively, he compiled 14 saves, tying the Illinois single-season saves record. His dominant performance earned him recognition on the All-Big Ten Third Team, signaling his readiness for professional baseball.
