Early Career
Fajing Sun’s tennis journey began on Shanghai’s public courts, where he first gripped a racket at age six.
His parents, spotting raw talent, enrolled him in a local academy by eight, kickstarting a routine of dawn-to-dusk training balanced with schoolwork. By 12, he dominated regional junior events, earning the nickname “Swift Shadow” for his blistering court coverage. Coaches praised his two-handed backhand—a stroke he refined into a tactical weapon during endless drills.
At 16, faced with choosing academics or tennis, Sun opted for the latter, dropping out to train full-time under Wang Zhijun, a former Davis Cup player. The gamble paid off in 2014 when he claimed the China Junior Tennis Championships in Guangzhou, showcasing a fearless net game that bewildered higher-ranked rivals.
His pro breakthrough arrived in 2016 via a wildcard doubles entry at the Chengdu Open, partnering He Yecong. Though they fell in the first round, the exposure to ATP-level tactics proved invaluable.
For the next three years, Sun grinded through Asia’s ITF Futures circuit, often bunking in budget hotels between matches. Persistence bore fruit in 2018 when he clinched his maiden Futures doubles title in Thailand, deploying clever lobs and sharp angles to outmaneuver taller opponents.
By 2019, his singles game surged, highlighted by a marathon semifinal run at the M15 Jakarta tournament, where he rallied from a set down against Australia’s Matthew Romios in a three-hour slugfest. These gritty displays cemented his reputation as a tenacious baseliner, using relentless defense to wear down foes.
Though hindered by a modest serve (rarely exceeding 110 mph), his elite footwork and anticipation propelled him onto the ATP Challenger circuit by 2022—marking his arrival on tennis’ global stage.
Professional Career
Fajing Sun’s professional career has been a story of gradual ascension through tennis’ ranks, marked by perseverance in both singles and doubles. After turning pro in 2016, he struggled initially on the ATP Tour, losing four consecutive doubles matches across Chengdu and Shenzhen Opens with various partners.
His breakthrough came on the ATP Challenger circuit, where he claimed three doubles titles—notably at the 2017 Suzhou Challenger and 2024 Hangzhou Challenger—showcasing his net skills and tactical versatility.
In singles, Sun gradually climbed to a career-high ranking of No. 276 in December 2024, fueled by gritty baseline play and victories over higher-ranked opponents like 2024 Shanghai Masters qualifier Borna Ćorić. While his ATP Tour main-draw appearances remain limited, Sun’s 2024 season highlighted his growth: he reached the doubles semifinals at Thailand’s Nonthaburi Challenger and scored five ITF World Tennis Tour singles titles, including a clay-court victory in Anning.
His playing style—a right-handed, two-handed backhand game anchored by exceptional footwork—has earned praise from coaches like Juan Manuel Esparcia. By 2025, Sun’s career prize money surpassed $300,000, though his ATP ranking fluctuated between No. 276–279 due to early exits at Pau and Manama Challengers.
Despite mixed results, his relentless work ethic keeps him in contention for wildcards at Asian ATP events, where he remains a crowd favorite for his tenacious rallies.
