Soon after, Fruhvirtova’s fellow 17-year-old compatriot Linda Noskova followed suit with a 6-3, 7-5 victory over 11th seed Anna Blinkova.
“I've known her since very young age,” Fruhvirtova said. “First time we played together was under 12s. We played in the national team together – 12 and unders, 14 and unders – then we kind of went different ways a little bit, playing different tournaments.
“She lives in a different part of the country so we don't practise together, but it’s obviously nice to see both of us getting there.”

While Noskova has yet to make her tour-level debut, she instead drew confidence from previous success on these courts as last year’s girls’ singles champion.
“It means a lot. I was really excited to come back here, especially for the adults,” Noskova said. “It brings memories and that is one of my favourite, so it's really good.”
