Petra is just so consistent nowadays, even at tournaments that she has always traditionally struggled in. Her increased fitness has really helped her in this way I think. Sakkari or Kontaveit next will be very different challenges but if she maintains this level I don't think anyone is really going to stop her, at least not at this stage of the draw.
I was hoping to see this but it was over too quickly for BT Sport to show! Petra back on soon v Sakkari.
I think she has to make the semis to get a top 4 rank for RG?? Mladenovic beating Barty is a better match up if she can get past Maria.
