First, Yulia Putintseva stunned Magda Linette 7-5 6-3 before Wimbledon champion Rybakina doubled their advantage.

The best-of-five qualifiers feature two singles matches on Friday and two reverse singles on Saturday plus a doubles rubber.
“Magda is a rather difficult player so it’ll be a difficult match,” Rybakina said, looking ahead to her clash with Linette.
“I hope today’s match will allow me to feel more confident tomorrow. I’ll prepare and hope that I’ll be able to win.”
