Olga Danilovic claimed her second career WTA Tour title after beating qualifier Caroline Dolehide 6-3, 6-1 in the WTA Guangzhou Open final on Sunday.

Danilovic dropped only one set during her Guangzhou title run, besting Erika Andreeva, Diane Parry, Mananchaya Sawangkaew and top seed Katerina Siniakova in the semifinals.

"I'm so happy about the way I played the whole week, the whole tournament," Danilovic said.

"I'm so proud of myself and my team. I showed what I can do and prove it to myself, I'm so happy and very excited to be finishing the season this way," the 23-year-old Serbian added.

In the doubles final, top seeds Katerina Siniakova and Zhang Shuai eased past Katerina Piter and Fanny Stollar 6-4, 6-1. Siniakova and Zhang had not lost a single set during the week.

With the doubles title, Zhang has won two single titles and two doubles titles in Guangzhou in 12 years.

"Guangzhou Open is the most special one for me, I made my WTA tour debut here and won my first WTA title here," Zhang said.

The victory marks Siniakova's 27th career doubles title and fifth of the season. This is also Zhang's 14th career doubles title and first of the season.

"It is an event that has long history, when I was a kid, I watched Li Na to win her first title here and I am very happy to see more and more Chinese players enjoy their victory here, I want to give my gratitude to all who made this event happen," Zhang added.
