Ryan Seggerman Bio
Ryan Seggerman, born on August 6, 1999, is an American professional tennis player known for his steady rise through the ITF and ATP Challenger circuits. A native of San Diego, California, he turned professional after a standout college career and has built most of his reputation in doubles, where his aggressive returning and composed net play have made him a consistent threat on the Challenger tour. He reached a career-high ATP doubles ranking of world No. 71 on March 3, 2025, and has also posted a career-high singles ranking of No. 348, achieved on August 26, 2024.
Standing 193 cm tall, Seggerman uses his height and reach effectively on serve and at the net. After several seasons of steady development, he broke into the top 100 in doubles in 2024 and continued climbing during the early months of 2025 with deep runs at ATP-level events.
Early Life and Background
Ryan Seggerman was born on August 6, 1999, in San Diego, California, in the United States. Growing up in a region known for its year-round tennis climate, he had access to strong junior programs and competitive match play from an early age. San Diego’s mix of hard courts and active tournament scene helped shape his early development as a doubles-oriented player.
Details about his immediate family have not been publicly confirmed in verified sources. What is clear is that his pathway combined strong junior results with a deliberate decision to continue his tennis education in college before turning professional.
Path to Professional Tennis
Seggerman chose the college route to sharpen his game and test himself against high-level competition. He played college tennis at Princeton before transferring to North Carolina, where he continued to develop his doubles craft and gained experience in pressure-filled team environments. The move to a second competitive program allowed him to expand his game against varied styles and further prepare for the professional tour.
His transition to the professional ranks began on the ITF circuit, where he built match toughness and accumulated ranking points. The first major sign of his doubles potential came in 2023, when he and fellow American Patrik Trhac won eight consecutive ITF doubles titles between July and October 2023, a run that established them as one of the rising teams on the lower-tier tour.
Ryan Seggerman Career
Early Career (2023)
Seggerman opened his 2023 season by capturing his first ITF singles title at the M25 Monastir tournament, defeating Ilia Simakin 7–5, 6–4 in the final. That singles success demonstrated that he was more than just a doubles specialist and gave him confidence heading into the rest of the year.
His doubles game, however, moved faster. Partnering Patrik Trhac, the duo strung together eight consecutive ITF doubles titles between July and October 2023. Late in the year, they stepped up to the Challenger level and won their first ATP Challenger doubles title at the 2023 City of Playford Tennis International, then backed it up the following week by winning the 2023 NSW Open title.
ATP Tour and Grand Slam Debuts (2024)
The 2024 season marked Seggerman’s arrival on the main ATP and Grand Slam stages. After back-to-back Challenger titles leading into Indian Wells, he and Trhac received a wildcard into the Masters 1000 2024 BNP Paribas Open, making their ATP debut together. They upset sixth-seeded Máximo González and Andrés Molteni in the first round before falling in the round of 16 to eventual champions Wesley Koolhof and Nikola Mektić.
Building momentum, Seggerman and Trhac entered the 2024 Libéma Open as their second ATP-level event, a result that pushed Seggerman into the top 100 in doubles on June 24, 2024. The pair then won the 2024 Cranbrook Tennis Classic, their seventh Challenger-level title, lifting Seggerman to a new career-high doubles ranking of No. 89 on July 15, 2024. Later in the summer, they received a wildcard into the 2024 US Open, where they made their Grand Slam debut but were eliminated in the first round by Yuki Bhambri and Albano Olivetti. Seggerman also reached the final at the 2024 Szczecin Open with Szymon Walków, reaching a new career-high ranking of world No. 87 on September 16, 2024.
On the singles side, Seggerman reached the semifinals as a qualifier at both the 2024 Macedonian Open and the 2024 Cranbrook Tennis Classic. He broke into the top 400 for the first time on August 5, 2024, after qualifying at the 2024 Lexington Challenger, and later reached the quarterfinals of the RD Open, which lifted him to a career-high No. 350 on August 19, 2024.
2025 Breakthrough (2025)
Seggerman opened 2025 by winning a doubles title at the 2025 Canberra Challenger, partnering countryman Eliot Spizzirri and saving a championship point in the final against Pierre-Hugues Herbert and Jérôme Kym. He then made his Australian Open debut in doubles alongside Rithvik Choudary Bollipalli, falling in straight sets to eventual champions Harri Heliövaara and Henry Patten.
Partnering with John-Patrick Smith, he reached the semifinals of the 2025 Chile Open, where the pair lost to top-seeded Máximo González and Andrés Molteni. That result lifted Seggerman to a career-high doubles ranking of No. 71 on March 3, 2025. At the 2025 BNP Paribas Open, he rejoined Trhac as an alternate and the pair defeated top-20 singles players Karen Khachanov and Andrey Rublev 6–2, 6–7, 10–7, the same tournament where they had won their first ATP match a year earlier.
Driving Style and Strengths
Seggerman leans on his 193 cm frame to generate strong serving numbers and dominate with his overhead. In doubles, he is an aggressive returner and a calm presence at the net, willing to take balls early and pressure opponents into errors. His game travels well on hard courts, where his flat groundstrokes and clean volleys have powered his rise through the Challenger ranks.
Notable Events and Milestones
A signature milestone came at the 2024 BNP Paribas Open, where Seggerman and Trhac defeated a seeded team in their ATP debut and pushed eventual champions to a tight loss. Another came at the 2025 BNP Paribas Open, when they knocked off Karen Khachanov and Andrey Rublev as alternates. His eight consecutive ITF doubles titles with Trhac in 2023 also stand out as one of the longest such streaks of his career.

2025 Season Performance
The 2025 season has been the most consistent stretch of Ryan Seggerman’s career. He opened the year with a doubles title at the Canberra Challenger and backed it up with appearances at the Australian Open, the Dallas Open, Delray Beach, and Rio de Janeiro. His semifinal run at the 2025 Chile Open with John-Patrick Smith pushed him to a career-high No. 71 in doubles on March 3, 2025, confirming his place inside the top tier of ATP doubles players.
At the 2025 BNP Paribas Open, Seggerman reunited with Patrik Trhac as alternates and pulled off a marquee win over Karen Khachanov and Andrey Rublev. The victory highlighted his comfort on the biggest stages and his readiness to compete against top opposition. With consistent results and a clear upward trajectory, he enters the spring and summer hard-court swing with momentum.
Looking ahead, Seggerman’s priorities will be to maintain a top-75 doubles ranking, push deeper into main draws at Masters 1000 events, and compete regularly in ATP 250 and 500 tournaments. If he sustains his partnership form with Trhac and other regular partners, a first ATP title at tour level is a realistic next target.
