“I’m very happy – I’ve played a great three matches and I’m happy to be through to the second round,” Vekic said after the match.

The only previous time Vekic played Ivanovic, the match ended in a lopsided straight sets victory for the Serbian. But now with more experience, and with three matches in Cincinnati already under her belt in the qualifying rounds, Vekic came out looking more match fit and playing aggressively.

Vekic’s big forehand gave Ivanovic plenty of trouble throughout the match. The Croat earned a double break lead early on to build a 5-1 lead. Though the former No.1 eventually looked to be finding her rhythm and even got a break back to cut into Vekic’s lead, she wasn’t able to keep the unforced errors out of her game and Vekic took the first set 6-4.

She opened the following set with another break, punching back an Ivanovic volley with a deep cross court forehand. A lackadaisical backhand from Ivanovic drifted just wide and gave Vekic her first match point, on Ivanovic’s serve at 5-1, but the Serb held on after a pair of big serves and aggressive baseline play. Vekic took the match at the second time of asking, sealing it with a big inside-out forehand.

“I’ve played [Ivanovic] before and I know her,” Vekic said. “I just played my best tennis tonight and it was enough – I’m happy.”

Once ranked as high as No.62, Vekic has struggled with finding her form in recent months. With her win over Ivanovic, she’s well on her way to finding it again. She’s snapped a losing streak dating back to February – the 20-year-old hadn’t won a WTA-level main draw match since her first round win in Doha.

She faces another big task ahead in the form of British No.1 Johanna Konta in the second round. The No.10 seeded Konta sits at a career-high ranking of World No.13 after a spate of great results that has seen her reach the quarterfinals or better in seven events so far this year.

“I’m just gonna get back out there on the practice court and try to keep up my level,” Vekic said of the matchup. “Hopefully that’ll be enough again.”
