  • Of the 4 favourites for the title before the tournament, 2 of them are still in. Ashleigh Barty lost in round 3 to Shelby Rogers and Naomi Osaka lost in round 3 to Leylah Annie Fernandez.
  • Karolina Pliskova had the easiest overall draw at the start of the tournament, and she's still in the draw. Belinda Bencic now has the easiest overall draw relative to her ranking. Garbine Muguruza had the toughest overall draw, but she is still in the tournament, and still has the toughest draw of the players remaining.
  • Anna Blinkova had the easiest 1st round draw, and but she ended up losing to Valentini Grammatikopoulou. The player who had the toughest 1st round draw, Vera Zvonareva lost her first round match to Ashleigh Barty as expected.
