Coco vandeweghe advances to semifinals of the australian open 2017

CoCo Vandeweghe is through to her maiden Grand Slam semifinal after a masterclass performance against world No.7 Garbine Muguruza.

Her 6-4 6-0 victory is her third out of four meetings against the Spaniard, who was unable to combat the American’s power throughout the encounter.

The opening game was a sign of how the match would play out as the American piled the pressure on Muguruza, earning two break points that the Spaniard was able to save.

The seventh game of the set proved pivotal as the two players fought tooth and nail for every shot in a game that would ultimately last over 10 minutes. Vandeweghe eventually broke the Muguruza serve and quickly consolidated before taking the set 6-4.

The second set followed a similar pattern to the first, except Vandeweghe was able to take her chance and break in the opening game.

Vandeweghe was delighted with her performance, but work still needs to be done if she is to be satisfied with the tournament.

"I thought it was pretty good. I thought I took care of the things that I could control, which is the most important thing: not letting outside factors affect anything that was happening," she said.

"She's going to play some good points. I'm going to play some bad points. Also vice versa, I'm going to play some good points and she's going to play some bad points.

"It feels really good. It's amazing to be in a semifinal. But, you know, not satisfying. I want to keep going, keep playing. There's more things to do out on a tennis court that I'm hoping to achieve."
