Early Life and Background
Ryan Seggerman was born on August 6, 1999, in San Diego, California. Growing up in a region well known for its year-round tennis climate, he developed his game on the courts of Southern California and pursued competitive junior tennis from a young age. San Diego’s strong tennis culture and access to high-level coaching helped shape his early development as a player.
Seggerman balanced his tennis ambitions with a strong academic path. He attended Princeton University, where he played college tennis at a high level for the Tigers. Seeking a fresh competitive environment and a chance to compete for a national title, he later transferred to the University of North Carolina, continuing his collegiate career with the Tar Heels. His time at both programs gave him the structure and competitive schedule needed to prepare for the professional tour.
Path to Professional Tennis
After his college career, Seggerman transitioned to the professional circuit, beginning on the ITF Futures and Challenger circuits. In 2023, he broke through by winning his first ITF singles title at the M25 Monastir tournament, defeating Ilia Simakin in the final. The same year, partnering with fellow American Patrik Trhac, he won eight consecutive ITF doubles titles between July and October 2023, signaling his rapid rise on the doubles circuit.
By late 2023, the Seggerman-Trhac partnership claimed their first ATP Challenger doubles title at the 2023 City of Playford Tennis International, followed immediately by the 2023 NSW Open title the following week. These results established them as one of the rising American doubles teams and set the stage for Seggerman’s entry onto the ATP Tour in 2024.

Seggerman’s 2023 season marked his official arrival on the professional tour. In singles, he captured his maiden ITF title at the M25 Monastir event, a confidence-building result against a strong field. The victory gave him valuable ranking points and a foundation on which to build his singles game.
Even more impressive was his doubles campaign alongside Patrik Trhac. The American pair won eight straight ITF doubles titles over the summer and fall of 2023, building remarkable momentum heading into the Challenger level. They closed the year by winning back-to-back Challenger crowns at the 2023 City of Playford Tennis International and the 2023 NSW Open, announcing themselves as a team to watch on the Challenger circuit.

He then made his Australian Open debut with Rithvik Choudary Bollipalli, losing in straight sets to eventual champions Harri Heliövaara and Henry Patten. Partnering John-Patrick Smith, he reached the semifinals of the 2025 Chile Open, a result that lifted him to a career-high No. 71 in doubles on March 3, 2025.
At the 2025 BNP Paribas Open, Seggerman rejoined Trhac as alternates and produced one of the season’s biggest upsets, defeating a team of top-20 singles players, Karen Khachanov and Andrey Rublev, 6–2, 6(4)–7, 10–7. The pair later captured their tenth Challenger doubles title together at the 2025 Serve First Open, defeating Sriram Balaji and Bollipalli in the final. Across all four Grand Slams, Seggerman reached the second round at the 2025 French Open and 2025 Wimbledon in doubles, with first-round exits at the Australian Open and US Open.
Driving Style and Strengths
Seggerman’s game is built around his 1.93 m (6 ft 4 in) frame, which gives him natural leverage on serves and groundstrokes from the right side.

His comfort in high-pressure tiebreaks and championship-point situations, demonstrated multiple times on the Challenger circuit, underscores his mental toughness and composure in tight matches.
Notable Events and Milestones
Among the signature moments of Seggerman’s career are his 2024 BNP Paribas Open upset of sixth-seeded González and Molteni, his 2025 BNP Paribas Open victory over Khachanov and Rublev, and his streak of eight consecutive ITF doubles titles with Trhac in 2023. Reaching the top 100 in doubles in June 2024 and later breaking into the top 75 in 2025 stand as clear markers of his continued ascent in the professional game.
