US Open winner Emma Raducanu has made a touching promise to organisers of the Transylvania Open ahead of her quarter-final clash against Marta Kostyuk.The 18-year-old is competing in her father’s home country of Romania for the first time, progressing to the last eight of the WTA 250 event in Cluj-Napoca.She has beaten Polona Hercog of Slovenia and Romania’s Ana Bogdan so far, with a quarter-final against Kostyuk scheduled for this evening.Raducanu seems to be enjoying her time at the Transylvania Open. Her recent promise to tournament director Patrick Ciorcila certainly suggests this is the case.According to Tennis World, Raducanu and her father have promised to play at every edition of the Transylvania Open."I talked to her and her father, they are very attached to Romania, they really wanted to come here, and they feel very good," Ciorcila said."Emma Raducanu said that she will come to every edition that we will organise in the future."

Although the Transylvania Open is being played behind closed doors, Raducanu has still captured hearts and minds around Romania, particularly by giving an interview in the language of the host country.

"Everyone adopted Emma, ​​because she conquered everyone with that speech in Romanian," Ciorcila said. "Some people thought that Emma does not speak Romanian at all, here she speaks very well, with the necessary accent."

Raducanu also endeared herself to the people of her mother’s home country China by speaking in Mandarin in an interview after the US Open.

The Briton shot to prominence after winning the Grand Slam last month, defeating Leylah Fernandez 6-4, 6-3 in the final at Arthur Ashe Stadium.

She became the first qualifier, male or female, to earn a Grand Slam title, and the first British woman to win a Grand Slam title since Virginia Wade in 1977. Raducanu made history in style, not dropping a single set on her way to victory.

The young talent had a minor setback as she looked to continue her meteoric rise, losing in the opening round of Indian Wells. But she has now found her form again at the Transylvania Open.

Raducanu will revisit an old rivalry in the quarter-finals, having often played the 19-year-old Kostyuk at a junior level.

"Marta is a great opponent, she absolutely destroyed me in the juniors every single time, so it will be an interesting match, I’m looking forward to it," Raducanu said.
