It’s been another historic year for Turkish tennis at the TEB BNP Paribas Paribas Istanbul Cup as two homecrowd favorites Cagla Buyukakcay and Basak Eraydin book quarter-final berths.

On the second match Garanti Koza Arena, qualifier Basak Eraydin was victorious in the all-Turkish encounter. Following her maiden WTA match win over 7th seed Tsvetana Pironkova, 22-year-old put on another strong performance against compatriot Ayla Aksu.

Eraydin needed 68 minutes to knock out Aksu – who’s also appearing in the second round of WTA event for the first time – and reached maiden tour-level quarter-final with a comfortable 6-1, 6-3 win.

She’s now on a nine-match winning streak prior to her last eight match-up with 3rd seed Irina-Camelia Begu.

After making a solid start for title defense, Cagla Buyukakcay added one of the best wins of her career on home soil. Turkish trailblazer stunned second seed and doubles partner Timea Babos to move into quarters.

Despite playing in Istanbul without a WTA match win in 2017, Buyukakcay found her rhythm on her favorite location, Garanti Koza. As the clock reached the two-hour mark Buyukakcay scored the upset of day 4 as she took down world no. 30 Babos 6-4, 7-6(5).

Cagla, who underlined the power that she gains from the fans, will next meet sixth seed Elise Mertens who earlier beat Sara Errani 7-6, 3-6, 6-3.
