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."
"I feel a bit emotional but not too much -- I know I really worked hard to get here, playing in semis of a Grand Slam."
"I'm calling it as my second career. So it's the first semi-final of the second career. I'm really enjoying it."
