She's got a great draw until the fourth round, so it'll be interesting to see it she gives a proper run here!
Kenin-Ostapenko, and Vika-Kuznetsova first rounds are hurting my soul. And Carla hadn't exactly been given an easy final go around - she's got Sloane to deal with straight off.
On paper we should see Serena-Kvitova in the fourth round, and I really think it's been so long since she's been in the quarters that we could see Serena activate another level if that happens... I really think her best chances in slams now are to run into old foes a.k.a. Kvitova/Muguruza/Halep/Azarenka/Sloane, who she still has scar tissue over.
