Harmony Tan produced a "breathtaking" display as the little-known Frenchwoman extended her remarkable Wimbledon run by thrashing British hope Katie Boulter.

A 6-1 6-1 victory on Court Two was achieved in just 51 minutes, a stark difference to the three hours and 11 minutes that it took Tan to fend off seven-time champion Serena Williams in round one.

The world number 115 is through to the fourth round now and assured of at least £190,000 in prize money.

She followed up the thrilling win over superstar Williams by taking out 45th-ranked Sara Sorribes Tormo in round two, but kept plenty in reserve for the clash with Boulter, emphatically dismissing the home player's challenge.

Boulter stunned last year's runner-up Karolina Pliskova in round two, but Tan was untroubled as her whirlwind Wimbledon debut reached new heights, making only five unforced errors in the match.

"I don't believe it yet. I think if I sleep a little bit tonight, tomorrow I will believe it, but it's amazing," Tan said in an on-court interview.

"I think I like grass. I've never played on that court, but I really like to play with some slice, volley, everything with my game, so I'm really happy.

"It was really emotional for the first round against Serena, and after that it was just playing match by match and today was really good tennis."

Former British number one Johanna Konta, speaking on the BBC, said: "That was breathtaking from Harmony Tan.

"I didn't expect it to be like that, that easy. Not at all. But there's tennis for you. I expect Katie would like to go and practise and come back and say, 'Can we play that again please?'."

Tan also made headlines in the opening week of Wimbledon when she pulled out of the doubles, citing injury, drawing an initially angry response from partner Tamara Korpatsch.
