J.T. Ginn Bio
John Thomas Ginn (born May 20, 1999) is an American professional baseball pitcher for the Athletics of Major League Baseball (MLB). A right-handed starter with a history of high strikeout totals, Ginn reached the major leagues in 2024 after a long development path that included a Tommy John surgery and several minor league stops. He was originally selected in the first round of the 2018 MLB draft and later in the 2020 draft by the New York Mets before eventually joining Oakland.
Across his amateur and professional career, Ginn has been recognized as one of the more promising arms to come out of Mississippi, combining a power fastball with a sharp breaking ball. After beginning his pro journey as a teenager drafted by the Los Angeles Dodgers, he revived his stock in college, recovered from injury, and steadily worked his way to the Athletics’ major league roster.
Early Life and Background
J.T. Ginn grew up in Brandon, Mississippi, a community just outside the state capital of Jackson that has produced several notable baseball players. He attended Brandon High School, where he developed into a two-way star as both a pitcher and a position player. Scouts followed him closely throughout his high school years, and he quickly became one of the most talked-about high school arms in the country.
As a junior in 2017, Ginn batted .482 with 16 home runs, showcasing rare athleticism for a pitcher. That summer, he was invited to pitch in the 2017 Under Armour All-America Baseball Game at Wrigley Field, an event that traditionally features many of the top amateur players in the nation. The appearance further cemented his status as a high draft prospect heading into his senior year.
In his senior season at Brandon High School, Ginn batted .419 with nine home runs and 27 runs batted in while also posting a 5–1 record and a 0.36 earned run average on the mound. His dominant performance earned him the Mississippi Gatorade Baseball Player of the Year award. Despite being a first-round talent, he elected to honor his college commitment to Mississippi State rather than turn professional out of high school.
Path to Baseball
The Los Angeles Dodgers selected Ginn with the 30th overall pick in the 2018 MLB draft, making him one of the youngest players taken in the first round that year. Rather than sign, Ginn chose to enroll at Mississippi State, betting on his long-term development in the Southeastern Conference. The decision was widely respected and gave him the opportunity to face top-tier college competition.
As a freshman at Mississippi State in 2019, Ginn made an immediate impact. He went 8–4 with a 3.36 ERA over 16 starts and struck out 103 batters across 80 innings, showing the kind of swing-and-miss stuff that had originally drawn professional interest. His performance was strong enough to earn him the 2019 Southeastern Conference Freshman of the Year award, putting him among the elite freshman pitchers in college baseball.
The following March, Ginn underwent Tommy John surgery, sidelining him for an extended stretch. He was subsequently drafted again, this time by the New York Mets with the 52nd overall pick in the 2020 MLB draft. He signed with the Mets on June 30, 2020, for a $2.9 million bonus. Because the minor league season was canceled that year due to the COVID-19 pandemic, Ginn did not play a professional game, using the time to continue his recovery from surgery.
J.T. Ginn Career
Early Career (2020-2021)
After the canceled 2020 season, Ginn returned to action in June 2021, making his professional debut with the St. Lucie Mets of the Low-A Southeast. The debut marked his first appearance in a minor league uniform and gave him his first chance to test his arm against professional hitters following the long layoff caused by his elbow surgery.
He was promoted to the Brooklyn Cyclones of the High-A East in July 2021. Over 18 combined starts between the two affiliates, Ginn went 5–5 with a 3.03 ERA and 81 strikeouts across 92 innings, numbers that suggested his arm was fully healthy and that his stock was once again on the rise.
Minor League Development (2022-2023)
On March 12, 2022, the Mets traded Ginn and Adam Oller to the Oakland Athletics in exchange for veteran pitcher Chris Bassitt, giving Ginn a fresh organizational home. He opened the 2022 season with the Midland RockHounds of the Double-A Texas League and also made appearances for the rookie-level Arizona Complex League Athletics. In 12 starts across those two affiliates, he went 1–4 with a 5.10 ERA and 46 strikeouts in just over 42 innings.
The 2023 season proved more difficult. Ginn made only 8 starts across his minor league assignments and struggled to a 7.43 ERA with 17 strikeouts over 26⅔ innings, prompting the organization to take a more patient approach with his development heading into 2024.
Athletics Era and MLB Debut (2024-Present)
Ginn began the 2024 season with Midland, posting a 4–1 record and a 4.15 ERA over 6 starts. His strong play earned him a May promotion to the Triple-A Las Vegas Aviators, where he went 4–3 with a 5.72 ERA and 69 strikeouts across 15 games and 14 starts. On August 20, 2024, the Athletics selected Ginn to the 40-man roster and promoted him to the major leagues for the first time.
In 8 appearances and 6 starts for Oakland during his rookie campaign, Ginn went 1–1 with a 4.24 ERA and 29 strikeouts across 34 innings pitched, offering a glimpse of the strikeout ability that had defined his amateur background. Following the season, he was optioned to Triple-A Las Vegas to begin the 2025 season.
Driving Style and Strengths
Ginn is best known for his swing-and-miss repertoire, headlined by a power fastball and a sharp breaking ball. Throughout his amateur and professional career, he has consistently produced strong strikeout rates, peaking with 103 strikeouts in 80 innings during his freshman year at Mississippi State and recording 81 strikeouts in 92 innings in his first full minor league season.
Notable Events and Milestones
Ginn’s career has been defined by a series of comeback moments, from declining the Dodgers’ first-round offer in 2018 to returning from Tommy John surgery in 2021 and finally reaching the major leagues on August 20, 2024. His debut in an Oakland uniform was the culmination of a development path that spanned six years from his initial draft selection.
J.T. Ginn Career Wins
While detailed professional win totals for Ginn remain limited in the available record, his career has been marked by strong strikeout production and steady progression through the minor league ranks. The 2021 season stood out as a high point in his early professional career, when he posted a 3.03 ERA across 18 starts in his first full year back from injury.
Minor League Highlights
Ginn’s most significant minor league win totals came during the 2021 season between Low-A St. Lucie and High-A Brooklyn, when he won 5 games and struck out 81 batters in 92 innings. His 2024 work in the Athletics system included 4 wins at Double-A Midland and 4 more at Triple-A Las Vegas, setting the stage for his major league promotion.
Other Wins and Performances

J.T. Ginn Family

Personal Life
Public details about J.T. Ginn’s personal life, including his marital status, are not widely documented. He continues to focus on his professional baseball career with the Athletics organization.
2025 Season Performance
J.T. Ginn began the 2025 season with the Triple-A Las Vegas Aviators after being optioned by Oakland following his 2024 rookie campaign. The early portion of the year gave him an opportunity to refine his command and build on the strikeout tendencies that defined his late-2024 debut in the majors.
Throughout the 2025 season, Ginn’s primary objective has been to position himself for a return to the Athletics’ major league rotation. With a strong mix of minor league innings and the possibility of additional call-ups, his performance in Las Vegas remains a key storyline for Oakland’s pitching depth.
Looking ahead, Ginn’s blend of swing-and-miss stuff and improving health makes him a candidate to factor into Oakland’s long-term plans. If he can continue to translate his minor league strikeout numbers into consistent major league results, he could carve out a regular role in the Athletics’ rotation in the seasons beyond 2025.
