"Playing against Paula is always tough," Samsonova said on court after her win. "She’s doing unbelievable, so I’m really proud that I stayed on the court until the end. ... I think I’m growing match after match, day by day. I know it’s a long journey, and I hope to continue like that."

Samsonova now has a 3-0 head-to-head lead over Badosa. Four of the last six sets in their rivalry have been settled by tiebreaks -- with each player winning two.

Badosa squeaked out the first set in 77 minutes, but Samsonova held firm to take the 73-minute second set. The duo exchanged breaks in the first two games of the decisive third set, and Badosa held break point to take a 3-1 lead.

But Samsonova saved the break point with a fiery forehand landing on the back of the baseline, eventually holding for 2-2. Samsonova took control for good with a break at love for a 4-3 lead.

No.14 seed Samsonova converted her second match point at 5-4 to seal the 53-minute final set and line up a second-round meeting against No.24-ranked Zheng Qinwen.

Earlier on Sunday, Zheng beat Zhang Shuai in a first-round match between China's highest-ranked singles players.
