Harriet Dart Wins Guangzhou Open as Marion Bartoli’s Belief Fuels Her Late-Career Rise
After a qualifying-to-title run in Guangzhou, Dart credits part-time mentor Marion Bartoli with strengthening her belief and sharpening her game.

Harriet Dart’s first WTA title arrived at 30 after a run that tested her from the opening rounds—and she says the belief of part-time mentor Marion Bartoli has helped her see more in her own game.

Dart came through two qualifying rounds to reach the main draw at the Guangzhou Open, then beat three seeded players on her way to the trophy. The final brought another demanding test: she recovered from losing the first set to defeat Austria’s Lilli Tagger 4-6, 6-3, 6-4. For Dart, the title was not just a breakthrough result. It was evidence that the work she believes remains ahead of her can still translate into progress on court.
Tagger, 12 years younger than Dart, is ranked 53rd in the world, eight places below her career high. Dart’s win over her in the final capped a week in which the Brit also beat second seed Janice Tjen in the second round and fifth seed Paula Badosa in the quarter-finals. The path matters: Dart had to earn her place in the draw before taking on a series of higher-seeded opponents, then had to adjust after dropping the opening set of her first WTA final.
A final won through recovery
The scoreline tells a compact story of the final’s turning point. Tagger took the first set 6-4, leaving Dart to find a way back against a younger opponent ranked inside the world’s top 60. Dart levelled the match with a 6-3 second set, then closed it out 6-4 in the third. The result gave her a first title at WTA level and put a defining moment on a season built around repeated trips through qualifying.
After the win, Dart thanked her team and the crowd in Guangzhou. “I’ll try not to get too emotional,” she said. She described the week as fun and said she hoped to return next year. The celebration came with a ranking milestone attached: Dart was set to return to the top 100 on Monday, her first time back inside that group since November 2024.
Bartoli’s influence reaches beyond tactics
Among those watching the title run was Bartoli, the 2013 Wimbledon champion and former world No. 7. She joined Dart’s team on a part-time basis at the start of the season while continuing her work as a tennis analyst for broadcasters. Dart has spoken less about a single technical fix than about the confidence that has come from working with someone who has reached the sport’s highest level.
“It’s been quite incredible to work with Marion, and I was really fortunate she was open to working with me,” Dart said in an interview with BBC Sport. She acknowledged that she is at a different career stage from a 20-year-old player, but said she still sees room to improve and gains to make. Bartoli’s confidence in her, Dart added, has helped her believe more in herself.
That support appears to matter on two levels. Dart values Bartoli’s experience as a former champion, but also stressed the personal relationship: she said Bartoli cares about her as a person as well as working to improve her tennis. Dart called it invaluable to learn from her mentor’s experiences and said she hopes they can spend more weeks together next year. The arrangement is part-time, but Dart’s account suggests its value lies in the perspective and trust built across those weeks.
Form gives the title a wider frame
Guangzhou fits a strong stretch on hard courts. Since Wimbledon, Dart has won 19 of her 24 Tour-level matches on the surface. She has also played qualifying at her last five tournaments and reached the main draw each time. At the US Open and China Open, she won one main-draw match before falling in the second round. Those results show a player repeatedly finding her way into major draws, even before the Guangzhou title delivered a much larger return.
Dart was projected to rise to 83rd in the WTA rankings, more than 10 places below her career best of 70th. The title therefore brings her back into the top 100 while leaving a clear target ahead. Her best Grand Slam result remains a third-round appearance at Wimbledon, which she has reached twice. Guangzhou does not change that record, but it gives her a first tour-level title and fresh momentum as she continues to pursue a higher ranking.
The most telling part of Dart’s week may be the combination of persistence and recovery: two qualifying wins to enter the field, three seeded opponents defeated, and a final turned around after losing the first set. Bartoli’s belief has become part of how Dart describes that progress. The next measure will be whether she can carry the same conviction through more main draws and turn this breakthrough into a sustained climb.
