Garbine Muguruza and Ons Jabeur were the big winners in the second round of the Chicago Fall Tennis Classic on Tuesday.

In windy conditions Muguruza won 6-4 6-4 over 21-year-old American Ann Li and No. 6 seed Jabeur easily saw off Su-Wei Hseih 6-1, 6-0 in just 46 minutes.

“It was a difficult match just because (Chicago) is a windy city,” Muguruza said.

“Just controlling the mindset and not getting very frustrated because it´s difficult. With 6-4, 6-4, it was very tight. I think the match was very equal due to the circumstances, but I´m happy that I stayed calm in the 5-4, serving for each set, and I managed to close them out.”

No.7 seed Elise Mertens also made quick work of Ukraine’s Dayana Yastremska, winning 6-1, 6-3.

Anett Kontaveit blew away Madison Brengle of the US 6-4, 6-3 after a marathon journey from Ostrava.

Victoria Azarenka cruised past Zhang Shuai in just 61 minutes, 6-2, 6-1.

“I used to spend a bit of time in Chicago. One of the families I lived with when I was young, he was playing for the Chicago Blackhawks… so it felt special coming back here and knowing the support is here,” Azarenka said after the match.
