Between Akron and Trenton, he appeared in 42 games overall, compiling a 7–3 record with five saves, a 1.70 ERA, and 78 strikeouts in 58 and one-third innings.
New York Yankees Organization (2017–2019)
Feyereisen spent the next several seasons developing within the Yankees’ minor league system. In 2017, he split time between Trenton and the Scranton/Wilkes-Barre RailRiders, the Yankees’ Triple-A affiliate. He combined to go 2–3 with four saves and a 3.27 ERA in 63 and one-third total innings pitched across both levels, continuing to refine his craft as a reliever.
The 2018 season saw him remain with Scranton/Wilkes-Barre, where he posted a 6–6 record with one save and a 3.45 ERA in 60 innings pitched.

He went 10–2 with seven saves and a stellar 2.49 ERA, striking out 94 batters in just 61 innings. This dominant season positioned him for his eventual major league call-up and attracted attention from teams looking to acquire pitching depth.
Milwaukee Brewers (2020–2021)
On September 2, 2019, Feyereisen was traded to the Milwaukee Brewers in exchange for Brenny Escanio and international signing bonus pool money. The trade brought him to his home state of Wisconsin, providing an opportunity to play closer to his roots. Following the trade, he was selected to represent the United States national baseball team at the 2019 WBSC Premier12 tournament on October 10, and he was subsequently added to the Brewers’ 40-man roster.
Feyereisen made the 2020 opening day roster for the Brewers and achieved his lifelong goal of reaching the major leagues. He made his MLB debut on July 24, pitching one inning against the Chicago Cubs. In that debut appearance, he struck out former MVP Kris Bryant before giving up a solo home run to Anthony Rizzo. He appeared in six games during the shortened 2020 season, posting a 5.79 ERA as he adjusted to major league competition.
The 2021 season began with Feyereisen back with the Brewers. In 21 appearances with Milwaukee, he went 0–2 with a 3.26 ERA and a 1.09 WHIP, showing improved performance and adaptability at the major league level.
Tampa Bay Rays (2021–2022)
On May 21, 2021, the Brewers traded Feyereisen along with Drew Rasmussen to the Tampa Bay Rays in exchange for Willy Adames and Trevor Richards. This trade moved him to a Rays organization known for developing elite pitching. He made an immediate impact with Tampa Bay, appearing in 34 games during the remainder of the 2021 season with a 4–2 record and an impressive 2.45 ERA.
The 2022 season began exceptionally well for Feyereisen with the Rays. Through his initial appearances, he allowed only one unearned run in 24 and one-third innings pitched while limiting opposing hitters to a remarkable .086 batting average. However, his season was derailed in June when he suffered a shoulder injury that required surgery. After the 2022 season concluded, he underwent a procedure to repair the labrum and rotator cuff in his right shoulder. On December 13, he was designated for assignment by the Rays, bringing his tenure in Tampa Bay to an end.
Los Angeles Dodgers (2024–2025)
On December 14, 2022, the Rays traded Feyereisen to the Los Angeles Dodgers in exchange for minor league pitcher Jeff Belge. He spent the entire 2023 season rehabbing his shoulder injury and did not appear in any game activity, focusing on his recovery and preparation for a potential return to the mound.
Prior to the 2024 season, Feyereisen agreed to a $770,000 contract with the Dodgers in his first year of salary arbitration. He made his Dodgers debut on March 21, 2024, pitching one inning against the San Diego Padres in South Korea during the team’s opening series. He was optioned to the Triple-A Oklahoma City Baseball Club the following day. In 10 major league appearances for Los Angeles, he struggled with an 8.18 ERA and nine strikeouts across 11 innings. On July 3, he was removed from the 40-man roster and sent outright to Oklahoma City. He finished the 2024 season with a 2–6 record and a 5.48 ERA in 33 minor league games. He elected free agency on October 10, 2024.
Arizona Diamondbacks (2025)
On March 15, 2025, Feyereisen signed a minor league contract with the Arizona Diamondbacks. He began the season with the Triple-A Reno Aces and dominated early, posting a 0.96 ERA in his first seven appearances. His strong performance earned him a promotion when the Diamondbacks selected his contract on April 19, adding him to their active roster. He made two appearances for Arizona, logging an 0–1 record with a 9.00 ERA and two strikeouts over two innings. The Diamondbacks designated him for assignment on April 27.
Feyereisen returned to the Dodgers organization when he was claimed off waivers on May 1, 2025. He appeared in two games during this second stint with Los Angeles, allowing three earned runs on eight hits and a walk in two innings. He also made a brief appearance with Triple-A Oklahoma City, pitching two and two-thirds innings.
