Kiki Bertens captured her first WTA title of 2019 and her eighth overall on Sunday, defeating Donna Vekic of Croatia, 7-6, 6-4, in the final of the St. Petersburg Ladies Trophy in St. Petersburg, Russia.

Bertens, who remains at a career-high No. 8 in the world rankings after last week's win, was down 2-5 in the opening set of the final before rallying to win 17 of 18 points, forcing a tiebreak and taking the lead in the match. She broke Vekic early in the second set and then held on to win the championship in one hour, 43 minutes.

During the week in St. Petersburg, Bertens avenged losses she had suffered in January to her opponent in the final, Vekic, and to her quarterfinal challenger, Anastasia Pavlyuchenkova. She lost to Vekic in the Round of 16 at Brisbane, and she fell to Pavlyuchenkova in the second round of the Australian Open.

They Said It!

"There was a time when I was feeling too much stress on the court, and I didn't enjoy tennis at all. I was close to quitting the game and had to get my energy and focus back. I set some new goals for 2018, and it ended up being my best year so far. Right now, I'm just enjoying my life, and tennis. I'm a really happy person right now." – Bertens told wtatennis.com following her St. Petersburg victory
