Those easy faults for Julia here and there are normal but that is a problem of many girls, just look at Sharapova, she plays horrible often as well.
Thing is that u have to try somehow to avoid such cheap errors in the most important situations and that´s what Julia was able to do most of the time in her previous matches.
But different story when u play the world no1 in a final and already won 4 games in a row before (saved MPs etc.)
Happy to see that Julia didn´t give up here, fought till the end and played some amazing tennis here and there, definitely is on a good way if she keeps playing like that.
A shame that her serve is not effective at all against Azarenka but not the only one who has problems to hold against Azarenka. In general u have to say that Julia´s return also isnt her best shot but she did really well in the end where he punished Azarenka´s serve that´s how u have to play it.
Now don´t withdraw from Lux
