Re: Beijing QF  Maria Sharapova d. Angelique Kerber 6-0 3-0 ret.
There's no video of Masha twisting anything at the YEC. She quit after fully playing and losing two matches. She ran away cuz she basically wanted to avoid an inevitable humiliation by Azarenka.
However having said that, I do not fully equate that quitting with today's quitting (because one is pre-match the other mid-match).
Looked pretty bad in Tokyo, she skipped Beijing and tried it in Istanbul since she was going to be there anyway (bf at the time). And Azarenka was going to throw it regardless so she could have had an easier SF, so it would have been pathetic watching Vika try to lose to gimpy Masha. There was no humiliation coming that she was avoiding. Gave the points to Bartoli who made the trip all the way there and was sitting on the bench.
