In a display of pure determination and mental fortitude, Britain's Francesca Jones showcased why she's become one of tennis's most inspiring stories, fighting through injury and difficult conditions to reach the quarter-finals of the Auckland Classic.

The 25-year-old, currently ranked 72nd in the world, followed up her career-defining victory over world number 15 Emma Navarro with another gutsy performance against Austrian qualifier Sinja Kraus. Despite finding herself down a set and a break, and requiring physiotherapy treatment during the match, Jones refused to give in. Her remarkable comeback saw her win 12 of the next 14 games, eventually triumphing 1-6 6-4 6-1.

"I'm actually really relieved that's over," Jones shared with Sky Sport New Zealand, her gratitude evident. "When you play someone like Emma in the first round and you get through that, physically and mentally it's tough to pick yourself back up, especially in these conditions. I'm glad I got through that."

Jones's journey to professional tennis is nothing short of extraordinary. Born with Ectrodactyly Ectodermal Dysplasia (EEC), a rare genetic condition affecting her hands and feet, she was previously told by doctors that professional tennis would be impossible. With three fingers and a thumb on each hand, three toes on her right foot, and four on her left, Jones has rewritten what's possible through sheer determination and talent.

Her breakthrough year in 2025 saw her crack the top 100 for the first time, earning two WTA 125 titles along the way. Now, as British number three, she's proving that her success at the lower levels was just the beginning of an inspiring career trajectory.

During Tuesday's match, Jones faced sweltering conditions in Auckland that tested her resolve. She saved an impressive nine of the 13 break points she faced during the two-hour battle. "She was unplayable the first set and a half and I found it really tough to get used to playing in the day compared to the night. It's a lot quicker," Jones explained, showing the analytical mindset that helps her overcome challenges.

Looking ahead, Jones will face Chinese seventh seed Wang Xinyu for a coveted spot in the semi-finals, another opportunity for the rising British star to continue her impressive run.

The positive momentum wasn't limited to Jones. World number four Coco Gauff led defending champions the United States to the United Cup semi-finals with a commanding performance. Gauff defeated Greece's Maria Sakkari 6-3 6-2, then partnered with Christian Harrison for a thrilling mixed doubles victory that sealed their team's advancement.

Meanwhile, Wimbledon champion Iga Swiatek helped Poland reach the quarter-finals with an efficient 6-3 6-2 win, while Hubert Hurkacz successfully returned from a lengthy knee injury, showing that comebacks are possible with dedication and proper recovery.

Jones's story continues to inspire tennis fans worldwide, proving that limitations exist only when we accept them, and that the human spirit, combined with talent and hard work, can achieve remarkable things.
