ASB Classic's final female semi-final will test a resistance test for the 18-year-old Canadian sensation Bianca Andreescu.
Stanley Klase has played seven games, and he has spent more time in court with any other players in the tournament.
After the tournament champion, Andrescu was an iron woman.
In three games, they went on for more than two hours, against Williams against Williams for 14 minutes.
He has spent more than 12 hours in court, and has started cold from Thursday to Friday. On the contrary, his 30-year-old German opponent Julia Goerges has been in court for more than six hours.
Andreascu will go tomorrow against Goerges who lives in the morning. It's in its WTA ending number 14 and it has an excellent record of ASB Classic, as well as winning more than any other female history.
The Canadians, who played the second and third level events of last year, can not be told. I'm sure
Andreesco has faced this challenge this week and has mastered it. It starts the adrenaline and nerves, but that has been enough until now.
As far as anti-pyrotechnic aspects of Williams and Caroline Wozniack are concerned, Su-Wei Hsieh's 6-3 and 6-3 wins were not so impressive, but not so impressive.
Before this week, Andreescu won a player over 50 years over the course of three years. Now he has broken three times, not two older worlds, over three clear nights.
Hsieh is a tricky opponent. Has a great experience, two WTAs have two titles for two decades. Hsieh arrived in the fourth round in two Grand Slams, who won World No1 Simona Halep in Wimbledon last year.
With its orthodox game, with lots of slices, the rhythm of the ball and large angles and squares can be tough.
But Andreescu once again rose.
He spent most of his time out of the country house, giving him a point with a calm authority.
The Canadian has a perfect blend that is capable of creating the incredible power of the two wings, but also the plush blossoms.
And above all, it lives an incredible dream, and that's just the case.
"It's been a lot," said Andreascu. "At that moment I was very hard at work, it was a tough time, I have seen a lot of good young players."
