Ukraine’s Yuliia Starodubtseva, 26, celebrated the biggest win of her career against second-seeded compatriot Elena Rybakina at the French Open on Wednesday, and revealed that a bigger surprise could be in store, regarding a promise made by her boyfriend Pearse Dolan, who also happens to be her coach.

Starodubtseva said Dolan, 28, has promised to propose to her if she cracks the Top 50 of the WTA rankings — she’s currently ranked 55th, and needs one more win for her partner to fulfil his promise.
