That top quarter is one of the most brutal quarters of a Grand Slam draw that I've ever seen. Barty, Muguruza, Vekic, Bencic, Serena, Goerges, Kerber, then non seeded players like Riske, Kanepi and Sharapova. Whoever gets through that deserves to win it.
Second quarter is wide open for Bertens and Konta. Kvitova in there too but I doubt she'll be 100%.
Third quarter especially section 5 could get messy. Svitolina been in crap form, Sevastova's record at Wimbledon is dreadful, I'd favour Martic to get through that bit. Then section 6 you have Hsieh vs Ostapenko in the first round
The draw is in Karolina Pliskova's hands.
The final quarter could get messy, Halep, Keys, Venus, Sabalenka, Wozniacki, Garcia, Kenin and Osaka, some of those could easily crash out early. Osaka vs Putintseva again
Yastremska vs Giorgi, Venus vs Gauff, Cornet vs Azarenka, some really interesting matches in that quarter.
Very hard to predict some quarters, the way the draw looks though I'd have to favour Bertens and Pliskova.
