Early Life and Background
Jesse Allen Hahn was born on July 30, 1989. He grew up in Connecticut and attended Fitch Senior High School in Groton. During his high school career, Hahn established himself as a talented pitcher and played alongside future major league pitcher Matt Harvey. After graduating from high school, Hahn continued his baseball journey at Virginia Tech where he played for the Virginia Tech Hokies collegiate baseball team.
In the summer of 2009, Hahn advanced his development by playing in the prestigious Cape Cod Baseball League for the Chatham Anglers, a league known for showcasing top college talent. His promising career trajectory faced a significant setback in 2010 when he suffered an elbow injury to his throwing arm and underwent Tommy John surgery, a common but serious procedure for pitchers that typically requires an extended recovery period.
Path to Professional Baseball
Despite the injury concerns, the Tampa Bay Rays selected Hahn in the sixth round of the 2010 MLB draft. The Rays signed him to a $525,000 signing bonus, demonstrating their confidence in his potential despite the recent surgery. Due to the lengthy rehabilitation process required after Tommy John surgery, Hahn did not make his professional debut until 2012, giving his arm adequate time to heal and rebuild strength.
Hahn steadily progressed through the Rays minor league system over the following seasons. His performance earned him a spot on the Rays 40-man roster on November 20, 2013, indicating the organization viewed him as a significant part of their future plans. His dedication to returning from injury and continuing his development showcased the resilience that would come to define his career through multiple comeback attempts.

San Diego Padres (2014)
On January 22, 2014, the Rays traded 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.

The following season saw Hahn spend most of his time rehabilbing and in the minor leagues, appearing in only six games for Kansas City.

He compiled a 1-0 record with a stellar 0.52 ERA and 19 strikeouts in 17.1 innings pitched, demonstrating his ability to dominate when healthy.

Hahn appeared in 35 games for Oklahoma City, compiling a 4-1 record with a 4.75 ERA and 45 strikeouts across 41.2 innings pitched.
