Over the course of his career, he has accumulated 11 ATP Challenger Tour doubles titles and 8 ITF titles, along with appearances across all four Grand Slam doubles draws. His best Grand Slam singles-side result on the doubles court came at the 2023 US Open, where he advanced to the third round. He also reached a career-high singles ranking of No. 439 on November 22, 2021, demonstrating his versatility on both sides of the game.
Early Life and Background
Vasil Kirkov was born on March 13, 1999, in Asenovgrad, Bulgaria. He later relocated to the United States, where he built his tennis foundation and developed into a competitive junior player. His dual Bulgarian-American background has shaped his career path, giving him access to both European and American tennis circuits during his developmental years.
Kirkov trained extensively in the United States and eventually settled in Tampa, where he continues to base his professional training. The USTA junior system provided him with key competitive opportunities, allowing him to test his game against the top American prospects. His height and two-handed backhand became defining physical and technical traits during these formative years, helping him establish a strong baseline game suited for doubles competition.
Path to Tennis
Kirkov’s entry into professional tennis came through the USTA junior pathway. In 2016, he was awarded a qualifying wildcard at the US Open after reaching the final of the USTA National Boys’ 18 Championships in Kalamazoo, Michigan. That same year marked his transition to the professional ranks, signaling the start of his career on the international circuit.
The following year, in 2017, Kirkov made his Grand Slam doubles main draw debut at the US Open alongside Danny Thomas. The duo received their wildcard after winning the USTA Boys’ 18 National Hardcourt Championships in Kalamazoo. This breakthrough moment confirmed his potential as a doubles specialist and gave him valuable experience on the biggest stages in the sport.
Vasil Kirkov Career
Early Career (2016–2019)
During his earliest professional seasons, Kirkov focused primarily on ITF Futures and USTA Pro Circuit events, gradually building his ranking and match experience. In December 2019, he captured his first-ever ITF World Tennis Tour title at the M15 event in Cancun, Mexico. Entering as the No. 4 seed, he defeated No. 3 seed Nick Chappell in a dramatic three-set final, 6–7(3), 7–6(8), 7–6(1), showcasing the resilience that would later define his career.
These formative years allowed Kirkov to develop his doubles game and forge partnerships that would prove valuable in later seasons. His early exposure to high-level competition through wildcards and ITF titles laid the groundwork for his eventual breakthrough on the Challenger circuit.
Challenger Breakthrough (2023)
Kirkov’s rise on the Challenger Tour began in earnest in 2023. He won his first Challenger title at the 2023 Challenger Santa Fe, partnering Chilean Matias Soto. Shortly afterward, he captured his second Challenger crown at the 2023 Salinas Challenger alongside Alfredo Perez, defeating Ángel Díaz Jalil and Álvaro Guillén Meza in the final. These back-to-back titles in Latin America marked the emergence of Kirkov as a consistent doubles threat.
That same year, Kirkov reached the third round at the 2023 US Open after receiving a wildcard with Denis Kudla, before falling to Ivan Dodig and Austin Krajicek. The deep Grand Slam run further validated his growing reputation and contributed to his rising doubles ranking.
ATP Tour and Challenger Success (2024–2026)
In 2024, Kirkov continued building his profile. He entered the ATP 500 Mubadala Citi DC Open in Washington as a lucky loser, partnering Evan King, and also received a wildcard for the 2024 US Open doubles draw alongside Christian Harrison. These appearances at top-level events demonstrated his increasing presence on the main ATP Tour.
The 2025 season represented the peak of Kirkov’s career to date. In March 2025, he won three consecutive Challenger doubles titles in Latin America — in Santiago, Asunción (Paraguay), and Concepción (Chile) — all partnering Matias Soto. Following two Challenger finals in Asia, Kirkov broke into the top 100 in the doubles rankings on May 5, 2025, reaching world No. 98. He then captured his eighth Challenger title at the 2025 Wuxi Open with Bart Stevens, further cementing his status among the elite doubles players of his generation.
