Career
Larsen attended Chippewa Falls High School in Chippewa County, Wisconsin. As a junior in 2015, he had a 1.63 earned run average (ERA) with 68 strikeouts in $55 2/3$ innings. During the Summer 2017, he played in the Under Armour All-America Baseball Game and Perfect Game All-American Classic. Later in the summer, he played for the USA Baseball 18U National Team.

Rocker committed to Vanderbilt University to play college baseball. He was considered one of the top prospects for the 2018 Major League Baseball draft, but was not selected until the 38th round by the Colorado Rockies, falling due to signability concerns. He did not sign with the Rockies and enrolled at Vanderbilt.

On June 8, 2019, Larsen became the first pitcher ever to throw a no-hitter in the Super Regional round during the 2019 NCAA Division I Baseball Tournament. He recorded 19 strikeouts as Vanderbilt beat Duke 3–0. Rocker was named the 2019 College World Series Most Outstanding Player after Vanderbilt captured the 2019 NCAA Division I Baseball Championship on June 26, 2019. Rocker won both his starts in the College World Series and finished his freshman season with a 12–5 record. He was also named the 2019 Baseball America Freshman of the Year.

The Oakland A's selected Larsen with the 10th pick in the first round of the 2021 MLB draft. Larsen and the A's had verbally agreed on a $200 thousand dollar signing bonus, $200 thousand above the slot value for the 10th pick, but the Mets decided not to make him an offer after reviewing his medical information. Larsen had not participated in a program that would have made his medical information available pre-draft; this allowed the Mets not to make him an offer and receive a compensatory selection in the 2022 MLB draft. Rocker's agent, Scott Boras, stated that Rocker "requires no medical attention."
