Harmony Tan branded 'unprofessional' after quitting doubles following epic Serena Williams win

Harmony Tan – whose thrilling win over Serena Williams on Tuesday earned her legions of new fans at Wimbledon – has been branded “unprofessional” by her doubles partner after she pulled out of the competition.

Following her three-hour Wimbledon debut under the Centre Court lights, Tan had been due to team up with Germany's Tamara Korpatsch for the first round in the women's doubles on Wednesday afternoon.

They were scheduled as the third match on Court 5, but Tan pulled out with a thigh injury at the 11th hour. Once the draw has been made, players are unable to switch partners, so it meant Korpatsch was forced to withdraw from what should have been her first ever Wimbledon doubles tournament.

Tan's withdrawal is suspected to be a precautionary measure, as the injury has not impacted the 24-year-old's intention to play singles. The Frenchwoman remains scheduled to face Sara Sorribes Tormo of Spain in the round of 64 on Thursday.

Korpatsch, 27, lost in the women’s singles on Tuesday so used her Instagram account to lash out at Tan, whose decision to pull out effectively ended her Wimbledon tournament.

“Unfortunately my doubles Partner H. Tan retired from our doubles today,” she wrote. “She just texted me this morning. Let me wait here 1 hour before the match start. I'm very sad, disappointed and also very angry that I can't play my 1st Doubles Grand Slam. And It's really not fair for me. I didn't deserve that.

“She asked me before the tournament if we wanna play doubles and I said yes, I didn't ask her, she asked me! If you're broken after a 3h [hour] match the day before, you can't play professional. That's my opinion.”

Tan and Korpatsch were replaced by reserve pair Valentini Grammatikopoulou of Greece and her Thai partner Peangtarn Plipuech.

Regardless Tan will be back in action on Thursday, where her new fans will be hoping to catch another glimpse of the most adorable cheerleader at Wimbledon so far this fortnight.

Even with Venus Williams making a rare appearance in the Centre Court crowd, it was instead an enthusiastic, anonymous girl in Tan's box on Tuesday who stole the show. She got lots of television airtime for her wild celebrations during the dramatic match, and went viral on social media as a result.

Telegraph Sport spotted her cheering on Coco Gauff on Court 2 earlier that day, and has since been identified as Tan's coach Sam Sumyk’s niece.

Though a slightly tenuous link to Tan herself, it did nothing to dull the girl's support for the Frenchwoman and overall enjoyment of her memorable day out at Wimbledon.
