The 19-year-old Andreeva hammered 30 winners in victory to reach the last 16 on another day of hot, sunny conditions, which she says helps her game.

“It just suits me more to play at this (midday) time than later in the day.”

The winner said that despite her record over Bouzkova, the match was not easy.

“Every time we play, it’s a battle. She’s an amazing competitor.

“I started really well, and then I was rushing a bit,’ Kostyuk said. It was a tricky match – very humid today. 

“Everyone is feeling worse and worse with every day with this heat. I’m excited that it’s not going to be like this on Sunday anymore (cool change arriving).

“I had enough patience today to close this match in two sets, and yeah, just still be aggressive.”

Kostyuk added that she ignores her current win streak going into her fourth-rounder against clay powerhouse Swiatek.

“I don’t think about it, I just play match by match. It’s a Grand Slam. It’s

a different tournament. 

“I’m happy with the streak, of course, but I don’t think about it that much.”
