Fernando Romboli Bio
Fernando Romboli de Souza (born 4 January 1989) is a Brazilian professional tennis player who specializes in doubles. Standing 180 cm tall, he turned professional in 2006 and has built a steady career on the ATP Challenger and ATP Tour circuits, primarily on the doubles side. He reached a career-high ATP doubles ranking of world No. 40 on 8 September 2025 and also peaked at No. 236 in singles on 20 June 2011. Romboli is a two-time ATP Tour doubles champion and has long been based in Guaruja, Brazil.
Early Life and Background
Fernando Romboli de Souza was born on 4 January 1989 in Santos, in the state of São Paulo, Brazil. Santos, a coastal city, has long produced competitive tennis talent, and Romboli grew up within easy reach of established tennis clubs and tournaments. His formative years were spent in São Paulo state, where he developed the foundations of his game before moving into the international junior and Futures circuits.
From an early stage, Romboli showed a clear aptitude for doubles, a discipline that rewarded his tactical reading of the game and his consistency at the net. By the time he was a teenager, he was already competing in national-level events in Brazil. He turned professional in 2006 at the age of 17, choosing to focus on building a tour-level career rather than pursuing a college route abroad.
Path to Professional Tennis
Romboli’s early professional years were spent largely on the ITF Futures circuit, where he earned valuable match experience and ATP ranking points. He broke through in 2011 at the Seguros Bolívar Open Bucaramanga, a Challenger event where he entered the main draw through qualifying and won every match he played to claim his first Challenger Circuit title. That same year he received a wildcard into the Brasil Open, his first ATP World Tour main-draw appearance, where he faced Rubén Ramírez Hidalgo in the opening round.
His progress was interrupted in 2012 when he tested positive for the diuretics furosemide and hydrochlorothiazide and received an eight-and-a-half-month suspension. After serving the ban, Romboli returned to competition and gradually rebuilt his doubles ranking through Challenger and ATP events, laying the groundwork for his later breakthroughs on the main tour.
Fernando Romboli Career
Early Career (2006–2014)
Between 2006 and 2014, Romboli competed predominantly on the ITF Futures and ATP Challenger circuits in singles and doubles. His 2011 Challenger title in Bucaramanga marked his first significant breakthrough, and his wildcard appearance at the Brasil Open that year gave him a brief taste of ATP-level competition. The 2012 doping suspension forced him to step away from the tour for several months.
Upon his return, Romboli increasingly prioritized doubles, a discipline where his tactical instincts and reliable ball-striking translated into consistent results. He climbed steadily through the Challenger ranks, reaching finals and capturing titles while still competing in singles events at the Futures level.
ATP Tour Breakthrough (2021–2024)
Romboli’s first ATP Tour doubles title came at the 2021 Croatia Open Umag, where he partnered with Spain’s David Vega Hernández. The unseeded pair defeated top seeds Tomislav Brkić of Bosnia and Herzegovina and Nikola Ćaćić of Serbia to claim the trophy, giving Romboli his first title at the top level of men’s tennis. The win marked a turning point in his career and validated his decision to focus on doubles.
Over the following seasons, Romboli continued to accumulate ATP points through Challenger events and main-tour appearances, often partnering with a rotating cast of doubles specialists. By late 2024, he was established inside the top 60 of the ATP doubles rankings and was regularly qualifying for ATP 250, 500 and Masters 1000 main draws.
2025 Breakthrough Season (2025–Present)
At the age of 36, Romboli produced the best stretch of his career in 2025. Entering the 2025 BNP Paribas Open at Indian Wells as an alternate with John-Patrick Smith, he defeated Austin Krajicek and Rajeev Ram, sixth seeds Julian Cash and Lloyd Glasspool, and Yuki Bhambri and André Göransson to reach the Masters 1000 semifinals, his deepest run at that level. In April, he and Smith won his second ATP title at the Houston Open.
In May, Romboli reached his first ATP 500 final at the 2025 Hamburg Open alongside Andrés Molteni, falling to top seeds Simone Bolelli and Andrea Vavassori. In June, he reached his first grass-court final at the 2025 Nottingham Open with Smith, defeating top-seeded Argentine Guido Andreozzi and Frenchman Théo Arribagé. These results lifted Romboli into the top 50 of the ATP doubles rankings on 30 June 2025, ahead of Wimbledon. He peaked at No. 40 on 8 September 2025.
