Defending singles champion and 2015 doubles runner-up Cagla Buyukakcay had a good day at the office alongside partner Timea Babos at the TEB BNP Paribas Istanbul Cup.

On the second meeting of Garanti Koza Arena, Büyükakçay/Babos dropped only three games as they marched on to the quarter-finals with a 6-2, 6-1 win over Cornelia Lister/Alexandra Cadantu.

There were three locals on court while Ayla Aksu and Dayana Yastremska, who knocked out Andrea Petkovic in singles yesterday, defeated Pemra Ozgen/Melis Sezer 6-0, 6-7, 10/8 to move into the last eight.

Third seeds Nao Hibino/Danka Kovinic and fourth seeds Nicole Melichar/Elise Mertens were also among the winning doubles teams on day 2 in Istanbul.
