Feyereisen made his MLB debut in 2020 and built his reputation as a reliable relief pitcher. He was originally drafted by the Cleveland Indians in 2014 and has since been part of multiple organizations through trades, minor league deals, and waiver claims.
Early Life and Background
J.P. Feyereisen grew up in Wisconsin and attended River Falls High School, where he developed his skills as a pitcher. His time in high school helped him earn attention from college baseball programs, and he went on to play college baseball at the University of Wisconsin at Stevens Point.
During his college years, Feyereisen also played summer collegiate baseball with the Wisconsin Rapids Rafters, gaining valuable experience in a competitive environment. This combination of college and summer league play helped him refine his pitching mechanics and prepare for a professional career in baseball.
Path to Baseball
After his college career, Feyereisen entered the professional ranks when the Cleveland Indians selected him in the 16th round of the 2014 Major League Baseball draft. He signed with the Indians and was assigned to the Mahoning Valley Scrappers, where he spent his first professional season. That year, he pitched 17 scoreless innings and struck out 24 batters, a strong start to his minor league career.
In 2015, Feyereisen moved up the Indians system, playing for both the Lake County Captains and the Lynchburg Hillcats. He posted a combined 1–1 record with 12 saves and a 2.08 ERA across 47 and 2/3 innings, striking out 56 batters. The following season, he began 2016 with the Akron RubberDucks, continuing his steady progression through the minor leagues.
J.P. Feyereisen Career
Early Career (2014–2016)
Feyereisen’s early professional years were spent entirely within the Cleveland Indians organization. After his standout debut with Mahoning Valley, he advanced through the lower levels of the minors, showcasing his ability to pitch in high-leverage situations. His save totals and strong ERA numbers during this period helped establish him as a relief pitching prospect.
On July 31, 2016, the Indians traded Feyereisen, along with Clint Frazier, Justus Sheffield, and Ben Heller, to the New York Yankees in exchange for Andrew Miller. The Yankees assigned him to the Trenton Thunder, where he finished the 2016 season. Between Akron and Trenton that year, he posted a 7–3 record with five saves, a 1.70 ERA, and a 1.10 WHIP, striking out 78 batters in 58 and 1/3 innings.
New York Yankees System (2016–2019)
After being traded to the Yankees, Feyereisen continued his development in the upper levels of the minor leagues. In 2017, he split time between Trenton and the Scranton/Wilkes-Barre RailRiders, posting a combined 2–3 record with four saves and a 3.27 ERA in 63 and 1/3 innings. The following year, he remained with Scranton/Wilkes-Barre, going 6–6 with one save and a 3.45 ERA in 60 innings.
His best minor league season came in 2019, when he returned to Scranton/Wilkes-Barre and posted a 10–2 record with seven saves, a 2.49 ERA, and 94 strikeouts in 61 innings. That performance helped position him for an opportunity at the major league level.
Milwaukee Brewers (2019–2021)
On September 2, 2019, Feyereisen was traded to the Milwaukee Brewers in exchange for Brenny Escanio and international signing bonus pool money. He was later added to the Brewers’ 40-man roster and was selected for the United States national baseball team for the 2019 WBSC Premier 12 tournament.
Feyereisen made the 2020 opening day roster for the Brewers and made his major league debut on July 24, 2020, pitching one inning against the Chicago Cubs. In that appearance, he struck out former MVP Kris Bryant before allowing a solo home run to Anthony Rizzo. He pitched in six games that season, posting a 5.79 ERA. In 2021, he appeared in 21 games for the Brewers, going 0–2 with a 3.26 ERA and a 1.09 WHIP before being traded midseason.
Tampa Bay Rays (2021–2022)
On May 21, 2021, the Brewers traded Feyereisen and Drew Rasmussen to the Tampa Bay Rays in exchange for Willy Adames and Trevor Richards. He made 34 appearances for the Rays that season, posting a 4–2 record and a 2.45 ERA.
In 2022, Feyereisen was dominant in a limited role, allowing just one unearned run in 24 and 1/3 innings and holding opposing hitters to a .086 batting average. His season was cut short in June when he injured his shoulder. After the season, he underwent surgery to repair the labrum and rotator cuff in his right shoulder and was designated for assignment by the Rays on December 13.
Los Angeles Dodgers (2022–2024)
On December 14, 2022, the Rays traded Feyereisen to the Los Angeles Dodgers in exchange for minor league pitcher Jeff Belge. He spent all of 2023 rehabbing his shoulder injury and did not appear in a game. After the season, he agreed to a $770,000 contract with the Dodgers through salary arbitration, his first time going through that process.
Feyereisen made his Dodgers debut on March 21, 2024, pitching one inning against the San Diego Padres in South Korea. He was optioned to Triple-A Oklahoma City the next day. In 10 games for the Dodgers, he struggled to an 8.18 ERA with nine strikeouts across 11 innings. On July 3, he was removed from the 40-man roster and sent outright to Oklahoma City. In 33 minor league games in 2024, he posted a 2–6 record and 5.48 ERA in 42 and 2/3 innings. He elected free agency on October 10.
Arizona Diamondbacks (2025)

Feyereisen was designated for assignment by the Dodgers on May 25 and became a free agent two days later after rejecting an outright assignment to the minors.
Driving Style and Strengths
Throughout his career, Feyereisen has built his reputation as a relief pitcher capable of missing bats and limiting damage in short stints. His minor league track record shows a consistent ability to generate strikeouts, including a 2019 season at Scranton/Wilkes-Barre with 94 strikeouts in 61 innings. Even at the major league level, he has shown stretches of dominance, such as his 2022 stint with the Rays when he held opponents to a .086 batting average.
Notable Events and Milestones
One of the defining moments of Feyereisen’s career came on July 24, 2020, when he made his MLB debut for the Milwaukee Brewers and struck out Kris Bryant of the Chicago Cubs.
