Jesse Hahn Bio

Jesse Allen Hahn, born on July 30, 1989, is an American professional baseball pitcher who is currently a free agent. He has played in Major League Baseball (MLB) for the San Diego Padres, Oakland Athletics, Kansas City Royals, and Seattle Mariners. The Tampa Bay Rays selected Hahn in the sixth round of the 2010 MLB draft, beginning a career that has spanned more than a decade across multiple organizations.

Early Life and Background

Early Life and Background

Jesse Allen Hahn grew up in Connecticut and attended Fitch Senior High School in Groton, where he pitched for the school’s baseball team. During his high school years, he was a teammate of Matt Harvey, a pitcher who would later become one of the most recognizable names in Major League Baseball. That early connection helped shape Hahn’s understanding of what it took to compete at the highest levels of the sport.

After high school, Hahn attended Virginia Tech, where he played college baseball for the Virginia Tech Hokies. During the summer of 2009, he played collegiate summer baseball with the Chatham Anglers of the Cape Cod Baseball League, a respected developmental circuit for top college players. In 2010, Hahn suffered an injury to the elbow of his throwing arm and underwent Tommy John surgery, a procedure that reconstructs the ulnar collateral ligament and often requires a lengthy recovery for pitchers.

Path to Baseball

Path to Baseball

The Tampa Bay Rays selected Hahn in the sixth round of the 2010 Major League Baseball draft, valuing his arm talent despite the uncertainty surrounding his injury. He signed with the Rays and received a $525,000 signing bonus, signaling the organization’s confidence in his long-term potential. Because of his recovery from Tommy John surgery, Hahn did not make his professional debut until 2012.

Hahn worked his way back through the Rays’ minor league system and was added to the team’s 40-man roster on November 20, 2013. His progress through the minors showed enough promise that other organizations began to take notice. That winter, the Rays made a major trade that sent Hahn to the National League and put him on the path to the major leagues.

Jesse Hahn Career

Tampa Bay Rays Organization

The Tampa Bay Rays selected Jesse Allen Hahn in the sixth round of the 2010 Major League Baseball draft and signed him to a $525,000 signing bonus. He spent his first professional seasons recovering from Tommy John surgery and did not make his professional debut until 2012. Hahn continued to develop in the Rays’ minor league system and was added to the team’s 40-man roster on November 20, 2013, protecting him from the Rule 5 draft.

San Diego Padres (2014)

On January 22, 2014, the Tampa Bay Rays traded Jesse Hahn and Alex Torres to the San Diego Padres in exchange for Logan Forsythe, Brad Boxberger, Matt Lollis, Matt Andriese, and Maxx Tissenbaum. Hahn was brought up from the Double-A San Antonio Missions and made his major league debut with the Padres on June 3, 2014. He was optioned back to San Antonio the next day but was later recalled and finished the season strongly.

Hahn ended the 2014 season with a 7-4 record and a 3.07 earned run average across 12 starts, giving the Padres a promising glimpse of his potential. His late-season form positioned him as a building block for the franchise’s pitching staff heading into the following year.

Oakland Athletics (2015-2017)

On December 18, 2014, the Padres traded Jesse Hahn and R. J. Alvarez to the Oakland Athletics for Derek Norris and Seth Streich. In 2015, Hahn posted a 6-6 record with a 3.35 earned run average and led the major leagues in runners reaching base due to errors, with 14. That statistic reflected both the quality of his pitching and the infield defense behind him.

Over his three seasons with the Oakland Athletics, Hahn battled numerous injuries and inconsistency, appearing in only 38 starts. The inability to stay healthy limited his ability to establish himself as a long-term member of the rotation, and Oakland eventually decided to move on.

Kansas City Royals (2018-2021)

On January 29, 2018, the Oakland Athletics traded Jesse Hahn and Heath Fillmyer to the Kansas City Royals for Brandon Moss and Ryan Buchter. After experiencing discomfort in his ulnar collateral ligament during the beginning of spring training, the Royals placed Hahn on the 60-day disabled list to begin the season, and he missed the entire 2018 season.

Hahn spent the majority of 2019 rehabbing and in the minors, appearing in only six games for Kansas City. He was non-tendered on December 2, 2019, and became a free agent before re-signing with the Royals on a one-year contract on December 13, 2019. With the 2020 Kansas City Royals, Hahn appeared in 18 games, compiling a 1-0 record with a 0.52 earned run average and 19 strikeouts in 17.1 innings pitched, putting together one of the most effective stretches of his career. On May 22, 2021, Hahn was placed on the 60-day injured list with a right shoulder impingement, and he became a free agent after the 2021 season.

Los Angeles Dodgers Organization (2024)

After not pitching at any level since 2021 due to injury, Hahn signed a minor league contract with the Los Angeles Dodgers on January 17, 2024. He was assigned to the Triple-A Oklahoma City Baseball Club to start the season and pitched 41 and 2/3 innings over 35 games, compiling a 4-1 record and 4.75 earned run average with 45 strikeouts. Hahn was released by the Dodgers organization on August 29.

Seattle Mariners (2024-2025)

On September 4, 2024, Jesse Hahn signed a minor league contract with the Seattle Mariners. In 8 games for the Triple-A Tacoma Rainiers, he posted a 3.12 earned run average with 10 strikeouts across 8 and 2/3 innings pitched before electing free agency on November 4. Hahn re-signed with the Mariners on a new minor league contract on November 18, 2024.

Hahn was released prior to the start of the season on March 23, 2025, then re-signed with the Mariners organization on March 27. On April 5, the Mariners called Hahn up to their active roster after optioning Tayler Saucedo to Tacoma. After two scoreless appearances, he was designated for assignment on April 9, cleared waivers, and was sent outright to Tacoma on April 12. He rejected the assignment and elected free agency the following day, then re-signed with the Mariners on a minor league contract on April 15. On May 21, the Mariners selected Hahn’s contract, adding him back to the active roster, but he was designated for assignment again on May 23. He cleared waivers and elected free agency on May 26 before re-signing once more on June 3, eventually electing free agency following the season on November 6.
