Garbine Muguruza has set up an Australian Open semi-final showdown with fellow former world No.1 Simona Halep as they both look to add a third grand slam to their haul.

The Spanish veteran fired past Russian 30th seed Anastasia Pavlyuchenkova 7-5 6-3 while a ruthless Halep crushed Estonia’s Anett Kontaveit 6-1 6-1 in Wednesday’s earlier quarter-final at Rod Laver Arena.

Currently ranked world No.32, both Muguruza and Halep are former Wimbledon and French Open champions.

Halep has come closest to a title at Melbourne Park, losing the 2018 decider to Caroline Wozniacki in a three-set heart-breaker.

She fired a warning that she won’t let another opportunity slip, needing just 53 minutes to oust Kontaveit in a flawless display.

Kontaveit didn’t play that badly – only making 15 unforced errors – but Halep hunted down every ball and sent it back with interest.

The Romanian said she was feeling stronger than ever.

“I played my best game on court, I felt strong in my game, strong in my legs,” said the world No.3.

“I worked a little bit more in the off-season – for the first time in my life I did the off-season away from home so I could be focused on what I have to do every day, no days off.

“That meant a lot for me and this year, I started very well and I am feeling much stronger than before.”

Muguruza, whose last major semi-final appearance was at Roland Garros in 2018, had a tougher time against Pavlyuchenkova.

The pair traded breaks early in the second set before 26-year-old Muguraza stepped up her play.

A double-fault by the Russian handed her opponent a 2-4 lead and she was never headed from there.
