Very mature match from Linda Noskova, she served well when she had to and never really dropped her level.
To lose your serve in the last game of the set, Marta Kostyuk just wasn't able to step up to the plate in the important points and Noskova did. She stuck to her game plan.

Marta Kostyuk has been really trying to get herself fired up, letting out a big shout after the last few points she has won.
It’s not proving enough to unsettle Linda Noskova, though.
The 21-year-old looks so comfortable on this surface, winning more matches on grass than any women’s player since the start of last year.
She’s very much in pole position to reach her first major final now.
