Can't believe how did she defeat Sirotkina.
Calling Ana, women Karlovic is funny. She serves well but her 2nd serves are crap!! A good serve returner or a WTA top 100 player can easly slaughter her if she can't find her 1st serve.
Btw, I talked couple of times with her coach and he is a funny and nice man.
How can you explain that at the and of the first set she won 100% points after her second serve !? Percentage was always 60-70. I don't see any logic in that.
