Wozniacki, Vinci to clash for Istanbul title
Denmark's Caroline Wozniacki returns to Czech Republic's Barbora Zahlavova Strycova during their women's singles fourth round match on day seven of the 2014 Wimbledon Championships in Wimbledon, southwest London, on June 30, 2014 - by Carl Court
Wozniacki made the final with a 6-2, 6-3 win over France's Kristina Mladenovic while second-seeded Italian Vinci brushed aside Konjuh 6-4, 6-2.
Vinci had lost to Konjuh in the first round in Auckland this season in the pair's only other previous meeting.
"The conditions were difficult out there today with the wind, so it made everything a little harder," Wozniacki said of her clash with Mladenovic.
"I just tried to stay focused and play my best tennis and I'm glad it worked out."
Vinci leads Wozniacki 2-1 in head-to-head meetings, including beating the Dane when she was ranked number one in 2011 and also winning their only 2014 encounter.
Vinci is also on a roll, winning eight of nine matches since coming out of Wimbledon.
