Azarenka upsets Krejcikova, Jabeur overcomes Kalinina in Cincinnati

Twice champion Victoria Azarenka upset Czech 11th seed Barbora Krejcikova 6-3 7-5 on Tuesday (Aug 15) to reach the Cincinnati Open second round, while Tunisia's Ons Jabeur mounted an incredible comeback to beat Ukrainian Anhelina Kalinina 6-3 6-7(2) 7-6(2).

"It's really nice to know where I can go, what I can push, you know, and today was really tough. It was tough to believe I could win this match," said Jabeur, who is into the third round after a first-round bye.

"A lot of frustration in that third set but I'm glad I kept going."

The 34-year-old unseeded Belarusian Azarenka broke Krejcikova four times, saved three of five break points and won the final five games of a match lasting one hour 45 minutes.

Krejcikova battled to get the opener back on serve but Azarenka broke right back and then went on to serve out the first set in the following game on her second set point.

In the second set, Krejcikova grabbed the early momentum and it was Azarenka who had to come back from a break down and then kicked into a higher gear before saving two break points in the final game to serve out the match.
