World number one Ashleigh Barty looked every inch a potential Wimbledon champion after blasting fellow Australian Ajla Tomljanovic off Centre Court.

The 25-year-old powered into the semi-finals for the first time after hitting 23 winners, including an ace on match point, in a ruthless 6-1 6-3 victory.

Barty, who won the French Open in 2019, said: "I feel good. I think obviously playing on grass is very different. It's a different surface.

"The clay season was quite long. As for the grass season for me, it’s one tournament, pretty cut-throat. I think it’s about allowing myself time to feel relaxed on the court, to learn about the surface, to continue to kind of find my rhythm and find my groove on the grass.

"But I think today I was able to use my weapons a little bit better and just bring the ball back into my patterns a bit more regularly. I certainly wasn’t as loose as I have been with errors and kind of ill-timed lapses, I suppose.

"But I felt really sharp today. I felt like I knew I needed to bring that level in order to match it with Ajla."

Barty will face the 2018 Wimbledon champion Angelique Kerber in the last four on Thursday.

"It’s not scary or overwhelming, it’s just exciting," added Barty. "It’s exciting to have the challenge of playing someone who is comfortable on these courts, who knows how to win this tournament."

Angelique Kerber enjoyed a routine victory

Kerber remains on course for another final at the All England Club after dismantling Karolina Muchova in ruthless fashion in the last eight.

The 25th seed progressed into the semi-finals with a 6-2 6-3 victory following one hour and 15 minutes of action on Court One.

Muchova gave the German a big helping hand with a string of wayward shots and unforced errors to ensure her equal-best showing at the Championships ended with a disappointing display.

A long rally from the opening point of the match suggested a close encounter and that proved the case in the early exchanges.

Kerber was forced to work hard to hold on serve but despite her Czech rival forcing deuce on a number of occasions, the first break went to the 2018 Wimbledon winner and she found herself 3-0 up.

The 19th seed had played well to find herself with a large deficit and although she got off the mark in the next game, the first set was over in 34 minutes.

A double fault and two unforced errors by Muchova gave Kerber a second break which clinched the opener 6-2.

Once again Kerber was forced to fight on her own serve at the beginning of the next set and she saved three break points to hold.

It was a similar situation on her next service game and this time Muchova did make the most of it as the quarter-final threatened to turn into a contest.

But the two-time finalist at Wimbledon was able to win the break back straight away and reeled off four games in a row to move within touching distance of another last-four berth at SW19.

Another wayward shot from Muchova saw the second set wrapped up in 41 minutes to give Kerber a 10th consecutive win having started the year in poor form with first-round exits at the Australian Open and Roland Garros.

Kerber only produced 15 winners but held her nerve at the crucial moments, winning four out of six break points, to continue her fine tournament to date.

On the other side of the draw, Karolina Pliskova continued her career-best run at the tournament by knocking out surprise package Viktorija Golubic to reach the semi-finals.

The Czech former world number one (29) had never been beyond the fourth round at the All England Club but is yet to drop a set and eased to a 6-2 6-2 victory over Golubic.

The Swiss, ranked 66, was playing in her first grand slam quarter-final at the age of 28, with her scalps here including American duo Danielle Collins and Madison Keys.

Her one-handed backhand is a real crowd pleaser but ultimately Pliskova was far too solid, sweeping through the match in 81 minutes.

She'll face second seed Second seed Aryna Sabalenka who powered into her first grand slam semi-final with victory over Ons Jabeur.

This was a classic contrast of styles, with the big-hitting Sabalenka against the versatile Jabeur, and it was power that came out on top as the Belarusian secured a 6-4 6-3 victory in just 74 minutes.

Sabalenka had struggled to match her form on the WTA Tour at the slams, admitting she was finding it difficult not to put too much pressure on herself to break through the fourth-round barrier.

She achieved that with victory over Elena Rybakina on Monday and played freely in her first grand slam quarter-final, keeping Jabeur on the defensive and not allowing the Tunisian trailblazer to spin her web of disruption.

They were neck and neck for eight games but Sabalenka held serve to make it 5-4 and then clinched the set with the first break in the 10th game, taking her fifth set point.

Jabeur, who had fought back from a set down against both Garbine Muguruza and Iga Swiatek, was the clear crowd favourite and fought back from 0-2 to 2-2.

But Sabalenka pulled ahead again and saved another break point to serve out the match.
