This is what Azarenka said:
Meanwhile, Azarenka wasn't happy with her performance at all - she talked about it in her presser.
"It was an awful match and a very bad performance from me, so there's not much to say about it," the World No.2 commented. "It happens once, twice a year to every player, and it happened to me today."
Azarenka also lost her first match at last week's Toray Pan Pacific Open in Tokyo, to Venus Williams.
"If I did it all again, I probably should have taken a longer break and prepared myself better. I don't feel like I was ready to play - to be 100%, the preparation wasn't enough, I cannot deny that. It's my mistake for not paying enough attention after the US Open how I managed my time and managed my health.
"But you cannot put yourself down too much. In the end the important thing is how you come out of it. I'm going to go back, re-evaluate and practice more. I just needed more preparation, and that's what I'm going to get now before the last tournament. I'll just look at the positives. I have three weeks now."
This to me sounds like she should have done what Serena done and not play Tokyo. But the problem is unlike Serena (who already played 4 premier 5s), Vika stood to lost a lot by not playing Tokyo.
This just highlights the main flaw in the Asian swing. There is too little time between the end of the US Open and the big events in Asia. It needs to be at least 3 weeks. If you make the latter stages of the US Open these events come way too quick. I think Vika flew out to Tokyo on the Monday, 8 days after the US Open final, I imagine she barely picked up a racket in that time, you're never going to be well prepared under that schedule. Most the top players want to take some kind of time off after a grand slam, it's not possible in WTA after the US Open short of withdrawing from the Asian events.
It's even worse for Serena, Serena wins US Open, has to do days of press work after winning it, then you are expecting her to fly out to Tokyo a couple of days later? Just not going to work is it, so it's no wonder she withdrew from Tokyo. She probably did the smart thing taking an extra week off.
You have a situation where you have a packed spring - early summer with French Open and Wimbledon. Then most top players take some kind of vacation/break after Wimbledon recharging their batteries for the USO series. Probably the 3 most brutal switches on your body clock are upon arrival to Australia, the switch from Europe to America and the switch from America to Asia. Australia is the start of the season, so you can turn up as early as you like to get adapted. There is a full 5 weeks between the end of Wimbledon and the big events in the USO series beginning. Then you have 2 weeks between the end of the US Open and the big Asian events. This on the back of a long season too, it's just too quick a turnaround.
