Rafael Nadal brushes aside Tiafoe
Kvitova will face unseeded American Collins in the semi-final on Thursday.
Melbourne: Rafael Nadal continued his relentless march towards an 18th major title Tuesday as an emotional Petra Kvitova swept into her first Grand Slam semi-final since a terrifying knife attack almost ended her career.
On Day Nine of the Australian Open, the fairytale runs of Stefanos Tsitsipas and Danielle Collins were also extended as they too swept into the last four.
Second seed Nadal inched closer to winning an event he has only claimed once before when he trounced unseeded American Frances Tiafoe 6-3, 6-4, 6-2 in another ruthless display from a man who has not dropped a set so far.
Tiafoe had announced himself by beating fifth seed Kevin Anderson, but was no match for a player at the peak of his powers as he attempts to become only the third man to win all four Slams twice and the first to do so in the Open era.
“I had some trouble at this event all my career, so I’m very happy with the way I played tonight,” said the Spaniard, who faces another young gun Tsitsipas in the semi-finals.
“I feel lucky to be where I am.”
Greek sensation Tsitsipas powered into the last four with a measured 7-5, 4-6, 6-4, 7-6 (7/2) win over Spain’s Roberto Bautista Agut.
Czech Kvitova had not gone past the last eight at a major since a burglar slashed her left hand in December 2016, forcing her out of the game for six months and leaving her with lasting nerve damage in the fingers of her racquet hand.
But the eighth seed has bounced back and is on a sensational 10-match unbeaten streak after claiming the Sydney International warm-up title.
She proved too much for Ashleigh Barty, crushing the local hope 6-1, 6-4, and was in tears afterwards as she reflected on her long journey back to the top.
Kvitova will face unseeded American Collins in the semi-final on Thursday.
Collins, the world number 35, had never won a Grand Slam match before entering this year’s tournament but she stunned three-time major champion and second seed Angelique Kerber in round four.
And the 25-year-old from Florida continued her Cinderella run by bouncing back spectacularly to down Russia’s Anastasia Pavlyuchenkova 2-6, 7-5, 6-1 in the quarter-finals.
Paes-Stosur out
Veteran Leander Paes and his partner Samantha Stosur suffered a second round defeat in the mixed doubles event, ending India’s campaign at the Australian Open.
The unseeded pair lost 6-4, 4-6, 8-10 against Anna-Lena Groenefeld and Robert Farah.
