John Rooney Bio
John Rooney, born on January 28, 1997, is an American professional baseball pitcher who is currently in the Tampa Bay Rays organization. A native of Melrose, New York, Rooney has worked his way through multiple levels of professional baseball since being drafted in 2018. He has previously played in Major League Baseball (MLB) for the Houston Astros, making his major league debut during the 2025 season. Standing as a reliever who has spent the majority of his career in the minor leagues, Rooney earned his first MLB call-up after years of development across several organizations.
Early Life and Background
John Rooney was born and raised in Melrose, New York, a small community in Rensselaer County. He grew up in a region where baseball has long been a part of local sporting culture, and he developed his skills from a young age. Rooney attended Hoosic Valley High School, where he played on the school’s baseball team and built the foundation that would carry him into college athletics. His time at Hoosic Valley helped him grow as a pitcher and gain the attention of college recruiters.
After completing high school, Rooney continued his education and baseball career at Hofstra University, located on Long Island in New York. At Hofstra, he played college baseball for the Hofstra Pride, competing at the NCAA Division I level. During the summer of 2017, he broadened his experience by playing collegiate summer baseball with the Yarmouth–Dennis Red Sox of the Cape Cod Baseball League, one of the most prestigious summer leagues in the country. That exposure helped prepare him for the jump to professional baseball the following year.
Path to Professional Baseball
Rooney’s path to professional baseball accelerated in 2018 when the Los Angeles Dodgers selected him in the third round of the 2018 Major League Baseball Draft, with the 104th overall pick. The selection was a strong vote of confidence in his upside as a pitcher and marked his transition from amateur to professional play. He signed with the Dodgers and was assigned to the organization’s minor league system.
In his first professional season, Rooney split time between the rookie-level Arizona League Dodgers and the Single-A Great Lakes Loons. He impressed with a 1.80 ERA across eight starts, giving the Dodgers an early sign of his development potential. The following year he split the 2019 campaign between Great Lakes and the High-A Rancho Cucamonga Quakes, posting a combined 10-4 record and a 2.84 ERA with 89 strikeouts in 104 and two-thirds innings across 20 starts. That performance cemented his standing within the organization before the broader disruption caused by the COVID-19 pandemic.
John Rooney Career
Early Career (2018-2021)
Rooney’s professional career began with the Los Angeles Dodgers organization in 2018, when he pitched at the rookie and Single-A levels. After his strong debut, he returned to the Dodgers’ system in 2019, splitting time at Single-A and High-A and emerging as a reliable starter across the California and Midwest leagues. His combined 10-4 record and 2.84 ERA showed steady progress as he climbed the minor league ladder.
The 2020 minor league season was canceled because of the COVID-19 pandemic, and Rooney did not appear in any official games that year. When play resumed in 2021, he returned to action with the Double-A Tulsa Drillers, compiling an 0-2 record and a 4.08 ERA with 42 strikeouts across eight appearances, including five starts. Although the win-loss total was modest, the experience at Double-A helped him adjust to higher-level competition.
Tulsa and Oklahoma City Years (2022-2024)
Rooney spent the 2022 season with the Double-A Tulsa Drillers, making 24 appearances with 17 starts. He struggled at times, finishing with a 4-7 record and a 6.15 ERA while striking out 99 batters over 98 innings. The season served as a learning period as he worked to refine his command and adapt to advanced hitters.
In 2023, Rooney transitioned toward a bullpen role, spending time with both Tulsa and the Triple-A Oklahoma City Dodgers. Across 53 appearances with just one start between the two affiliates, he posted a combined 6-3 record and a 2.86 ERA with 69 strikeouts and three saves in 69 and one-third innings. The shift to relief work produced clearly improved results.
Rooney remained in the bullpen in 2024, making 53 appearances for the Triple-A Oklahoma City Baseball Club. He registered a 5-2 record and a 4.33 ERA with 71 strikeouts and one save in 60 and one-third innings pitched. After the season, he elected free agency on November 4, 2024, opening the door to a new chapter in his career.
Miami Marlins Era (2024-2025)
On November 13, 2024, Rooney signed a minor league contract with the Miami Marlins organization. He was assigned to the Triple-A Jacksonville Jumbo Shrimp for the 2025 season. Across 38 appearances, he compiled a 2-1 record and a 2.45 ERA with 45 strikeouts and four saves in 33 innings, showcasing the consistency he had built in relief roles.
His performance with Jacksonville earned him attention from contenders looking for bullpen help. On August 3, 2025, the Marlins traded Rooney to the Houston Astros in exchange for cash considerations. The Astros added him to the 40-man roster and promoted him to the major leagues for the first time, marking the culmination of years of professional work.
Houston Astros Era (2025)
After his trade to Houston, Rooney was optioned to the Triple-A Sugar Land Space Cowboys on August 5, 2025, without appearing in a game for the Astros. He became a phantom ballplayer during that brief window. On August 24, the Astros promoted him to the major leagues for a second time, giving him his MLB debut that night.
Rooney pitched one and one-third innings of relief against the Baltimore Orioles on August 24, 2025, but allowed a solo home run to Luis Vázquez in a 3-2 road loss. Two days later, on August 26, he was placed on the injured list with left elbow inflammation. He was transferred to the 60-day injured list on September 3, ending his season. On September 23, it was announced that he had undergone surgery to remove bone spurs and address tennis elbow. On November 6, the Astros removed him from the 40-man roster and sent him outright to Sugar Land, and he elected free agency the same day.
Tampa Bay Rays Era (2025-Present)
On November 15, 2025, Rooney signed a minor league contract with the Tampa Bay Rays, beginning the next phase of his career. The deal gave him an opportunity to continue his development within another organization known for developing bullpen arms. He is expected to compete for a role in the Rays’ system as he works back from elbow surgery.
Notable Events and Milestones
Rooney’s biggest career milestone came on August 24, 2025, when he made his MLB debut for the Houston Astros against the Baltimore Orioles. The appearance represented his first taste of the major leagues after seven professional seasons. His first MLB season was cut short by injury and subsequent surgery, but the debut itself marked a significant personal achievement.
