Kasatkina ends Tauson's streak in Russia

Daria Kasatkina has ended the winning streak of Danish qualifier Clara Tauson to progress to the second round of the St Petersburg Ladies Trophy.

Russia's Daria Kasatkina has held off surging Danish qualifier Clara Tauson to move to the second round of the St Petersburg Ladies Trophy.

Playing at home, the eighth seed Kasatkina beat 18-year-old Tauson 6-4 7-6 (0) in a tight match that had 11 breaks of serve.

"Of course it means a lot, because every match you win at home it counts twice," Kasatkina said.

Kasatkina joked that she wasn't too happy when she saw the draw and found out that the qualifier she was playing was Tauson.

Tauson won her maiden WTA title two weeks ago in Lyon and with her qualifying wins in St Petersburg extended her winning streak to 13 matches.

"But it was a very good match and I was happy that I was able to get it," Kasatkina said.

"Clara was playing super aggressive, and I know that's why she won in Lyon, because probably she likes to play indoors a lot.

"She's going to be very dangerous on the hardcourts and indoors especially."

In other matches, China's Wang Xinyu won a see-sawing battle with Bulgaria's Viktoriya Tomova 6-1 5-7 7-5 and qualifier Kamilla Rakhimova beat wildcard Daria Mishina 6-1 6-7 (2) 6-1.
