Naomi Osaka continued her impressive rise to the top with a commanding 6-4 6-1 win over Elina Svitolina that sealed her place in the Australian Open semi-finals.
The result moves the Japanese player, 21, into pole position in the race for World No.1 and she will stay there unless Petra Kvitova reaches the final or Karolina Pliskova wins the tournament.
The first five games of the opening set of the quarter-final were closely-contested, but both players still held serve without ever being taken to deuce.
All of that changed in the sixth game. Osaka really started to trouble Svitolina with her weight of shot, and the Ukrainian eventually succumbed to the third break point she faced.
The Japanese player surrendered her advantage immediately with a poor service game. Then she re-discovered her rhythm immediately to break Svitolina again.
But the World No.6 justifiably has a reputation as a fighter, and she drew on all her battling qualities to break straight back for the second time in a row.
That made it 5-4 to Osaka, and many would have expected the set to settle down again at this point. It did not happen, as the Japanese player put the Ukrainian’s serve under pressure again to force 0-40 three break points.
Svitolina dug in to save all three but, when she faced a fourth, she netted a backhand and the set went to Osaka.
Osaka races through the second set
The World No.6 completely fell apart on serve in the second game of the second set. Consequently, she rapidly found herself facing a set and 0-3 deficit in the match.
At the changeover, Svitolina called for the trainer because she was suffering from pain in her right shoulder. She received some treatment and then the action continued.
Victory looked almost certain for the reigning US Open champion at this stage. And she cemented that impression when she – incredibly – broke the Ukrainian for the fifth time in succession to make it 4-0.
Osaka had a slight wobble in game five. She made a couple of unforced errors to hand Svitolina a break point.
However, the World No.6 did not take advantage of the chance and, although she finally held serve in game six, she must have known the fight was over.
The Japanese player completed the formalities with a comfortable hold. She finished the match with two aces and a decisive smash and celebrated with a low-key fist-pump and a smile for the crowd.
“I tried to be as consistent as I can,” Osaka said in her post-match interview. “She’s a really great player and it’s unfortunate that she got injured.”
She continued, “Today I just had one goal – to try as hard as I can and not get angry. I didn’t do it well in the last two rounds but I think I did it well this time so I’m really happy with how I played.”
