Harriet Dart's Rise: From Doubts to Victory at Guangzhou
Harriet Dart had barely put the Guangzhou trophy down before her phone lit up like Centre Court on a July afternoon. Messages stacked up. Missed calls, notifications, the lot.
First, though, there were the people who mattered most. Her parents, Nick and Susie, watching nervously with friends at their north London tennis club. Her sister Phoebe. Then, once the family calls were done, the voice of a Wimbledon champion cut through the chaos: Marion Bartoli.
A Grand Slam champion in her corner
Bartoli has been in Dart’s ear since the start of the season, a part-time coach with full-time impact. The 2013 Wimbledon winner, once world number seven, has helped drag Dart from the fringes of the rankings back into the conversation.
When they started, Dart was outside the top 160. On Monday, she is projected to climb to 83rd. The Guangzhou Open title, sealed against rising Austrian teenager Lilli Tagger, is the gleaming proof of a partnership that has quietly been building all year.
"It's been quite incredible to work with Marion, and I was really fortunate she was open to working with me," Dart told BBC Sport from Guangzhou. At 30, she knows she is not the bright young thing any more. She also knows her window is still open.
"I'm obviously at a very different stage of my career to someone who is, say, 20. But I still feel I have a lot to improve and there are gains to be made. She really believes in me - that means the world to me. Seeing a Grand Slam champion having that belief has made me believe a lot more in myself."
The two live close to each other in Dubai, where they put in training blocks whenever Dart is not criss-crossing the globe on tour. Bartoli, now 42 and with a young family, cannot travel full-time. She doesn’t need to. Her influence still reaches the court.
Dart laughs that Bartoli still hits the ball “really well” in practice. That’s not a throwaway line. It matters. When your coach can still rip through the court, the standards stay high.
Winning without the coach courtside
In Guangzhou, Bartoli wasn’t in the player box. Instead, Dart travelled with fitness trainer Dario Gonfiantini and boyfriend Stephen Falck. No coach to lean on in changeovers. No reassuring nod from the stands.
So she worked it out herself. Point by point. Match by match. Bartoli, watching from home, sent over notes and observations, but once Dart stepped on court, the responsibility was entirely hers.
She handled it.
The title in China capped a blistering second half of the season. Since Wimbledon, Dart has won 19 of 24 tour-level matches on hard courts. Across the whole year on the WTA Tour, she has 23 wins from 34 matches – the best winning percentage of her career.
This is not a player scraping by on the margins any more. This is someone winning, consistently, against the grind of the tour.
"More than anything, Marion is just a great person. She cares about me as a person first and foremost, as well as improving me as a tennis player, of course," Dart said.
"It's been invaluable and amazing for her to share her experiences to make me better. I've learned a lot from her and look forward to continuing to learn more. I hope we will be able to spend more weeks together next year."
From doubts to defiance
Dart’s story has not followed a clean upward curve. She hit a career-high of 70 in 2024, backed by a run to the Wimbledon third round and the US Open second round. Yet across the past two seasons, she has spent long spells outside the top 100, her progress stalled and her weaknesses exposed.
Opponents knew where to go: the second serve. Too slow, too fragile, too prone to double faults. Under pressure, the doubts crept in. Questions circled not just about her game, but about her mentality. Could she handle the tight moments? Could she close?
In Guangzhou, she answered in the only language that matters at this level: scoreboard pressure. A series of comeback wins, matches where she had to claw her way back from behind, showed a different version of Dart. One who refused to fold.
"She's always had a fantastic work ethic and has always set the bar high with her professionalism," said Anne Keothavong, Britain’s Billie Jean King Cup captain. "But there is certainly more belief and confidence now. She's in a very good place.
"She's been grinding away on the tour for a long time and it's great to see someone who has put in a lot of time to succeed and win a big title."
Keothavong named Dart in her squad for September’s Billie Jean King Cup Finals. Dart didn’t play a live rubber, but she made an impression in practice with the ball-striking that has now translated onto the main tour.
A surge for British women
Dart’s breakthrough doesn’t sit in isolation. It drops into a late-season surge for British women across levels and continents.
On the Asian hard courts, Sonay Kartal reached the final of a WTA 1000 in Wuhan, a huge step into the elite tier. Katie Boulter pushed through to the semi-finals of a WTA 250 in Osaka. Back home, teenager Hannah Klugman lifted the biggest title of her young career at the Wrexham Open, a W100 event on the Challenger circuit.
"The way they're all performing towards the end of the season - at whatever level - has been impressive," Keothavong said. "It's not easy at this time of the season because there has been a lot of tennis played, but they've all capitalised and risen to the occasion.
"It's great reward for all their hard work and is encouraging for British tennis."
Encouraging, yes. But Dart’s win feels like something more than that.
This is a player who has heard the doubts, lived through the ranking drops, and kept going. A player now guided by a Wimbledon champion who still believes there is another level to reach.
The Guangzhou trophy will fly back with her, but the real question now travels with it: with belief restored and a Grand Slam winner in her corner, how far can Harriet Dart push this comeback?
