Two months after the end of their engagement, Caroline Wozniacki could join former fiance Rory McIlroy in becoming a champion on Sunday.

Wozniacki will play Roberta Vinci of Italy for the Istanbul Cup WTA title after they reached the final as seeded, 1 and 2, on Saturday.

While golfer McIlroy was building a six-shot lead heading into the final round of the British Open, Wozniacki was beating Kristina Mladenovic of France 6-2 6-3 in the Istanbul semi-finals.

She will play for her 22nd career title and first of the year against Vinci, who is 2-1 up in their head-to-heads.

Vinci beat teenage qualifier Ana Konjuh of Croatia 6-4 6-2 to go for her 10th WTA title in her 12th final.

Sixteen-year-old Konjuh was the youngest player to reach a WTA semi-final since a 16-year-old Donna Vekic made the Tashkent final in 2012.
