Laura Robson beat a top-50 player for the first time since her stunning Wimbledon run as the teenager overcame Klara Zakopalova in the first round of the China Open in Beijing.
After a tight opening two sets, Robson stormed home to win 7-6 (7/3) 4-6 6-1 against the world number 33 from Czech Republic in just over two hours.
The 19-year-old claimed the British number one status in China 12 months ago, and has gone from strength to strength since, highlighted by her performance at Wimbledon.
Robson memorably beat 10th seed Maria Kirilenko on her way to the fourth round in south-west London and was a quarter-finalist in Guanghzou a fortnight ago as she has risen to 38 in the world rankings.
After holding her nerve in the first-set tie-break Robson, who claimed four breaks of serve in the match, slipped up in the second to send the game to a deciding set.
Robson was not to be denied, however, as she sealed victory to book a second-round meeting with seventh-seeded German Angelique Kerber.
Robson reached the second round in Beijing last year where she was beaten by Lourdes Dominguez Lino, the player she beat in the first round of last month's US Open.
