Daria Kasatkina overcame Russian compatriot Mirra Andreeva 6-0 4-6 6-4 to win the Ningbo Open final in China on Sunday and capture her second title of the season.
Eastbourne champion Kasatkina, who has lost four finals this year, breezed through the opening set in double quick time as the 17-year-old Andreeva looked nervous.
After winning the opening game of the next set, Kasatkina faltered and her close friend Andreeva rallied to draw level when the world number 11 sent a backhand wide.
Andreeva built a 3-0 lead in the decider but the momentum swung Kasatkinas way again as the youngsters unforced error count climbed rapidly.
The 27-year-old Kasatkina clawed her way back to secure the eighth trophy of her career and she will break into the worlds top 10 on Monday.
