Sonay Kartal’s Breakthrough: British Tennis Prodigy Scores Stunning Upset, Ignites New Era

British tennis sensation Sonay Kartal continued her break-out 2025 season by sweeping past 14-seed Daria Kasatkina 6-2, 6-1 to reach the China Open third round in Beijing, her deepest run at a WTA 1000 so far. The 23-year-old from Brighton needed just 71 minutes to chalk up her second victory of the year over the world No. 14—evidence that her hard-court momentum is gathering pace ahead of the season-ending indoor swing. Kartal, currently ranked No. 81 after peaking at a career-high 44 in July, has now posted nine top-50 wins in 2025 and sits inside the live Race top 40. She will next face Australian teen Maya Joint, with a quarter-final berth—and a return to the top-60—on the line. A new benchmark for British tennis Kartal’s surge comes at a crucial time for British women’s tennis. With Emma Raducanu also through in Beijing, the duo have delivered the first double-British appearance in the third round of a WTA 1000 since 2016. Kartal’s all-court game—built on a rock-solid backhand and increasingly aggressive first-strike forehand—has translated into a 22-19 record this year, including her maiden WTA title in Rabat and a headline-making run to Wimbledon week two. Road from health scare to headline act Just two seasons ago Kartal’s future was uncertain after a mysterious breathing issue sidelined her for six months. A change in training load and a new nutrition plan overseen by coach Julie Hobbs steadied the ship and, in Kartal’s words, “let me trust my lungs again.” Since then she has added muscle, pace on serve, and belief—climbing from outside the top 500 in January 2023 to the verge of the top 40 today. Match breakdown vs Kasatkina • First-serve percentage: 72% • Winners/unforced errors: 24/12 • Break points saved: 4/4 Kartal neutralised Kasatkina’s trademark forehand angles by hugging the baseline and redirecting pace down the line, a tactic she says she “picked up watching Raducanu film.” The Russian struggled to counter, winning only 41% of her second-serve points. What’s at stake in Beijing A victory over Joint would guarantee Kartal at least 120 additional ranking points and propel her into provisional 57th. More importantly, a quarter-final in Beijing would all but lock up direct entry into the Australian Open main draw, sparing the qualifier grind that defined her early career. Beyond Beijing: goals and schedule • Guadalajara 500 (hard) – begins 13 Oct • Zhuhai Elite Trophy qualification race • Billie Jean King Cup Finals, Seville – Kartal is on captain Anne Keothavong’s long list With indoor strength—she owns a 14-3 record under a roof in 2025—and no points to defend until January, projections show Kartal could break the top 30 by year-end if she reaches one more semi-final at 500 level. Quote of the day “I’m finally playing the tennis I believed I had in me. The ranking will follow if I keep putting in these performances,” Kartal told on-court interviewer Fabrice Santoro.
