  • Elina Svitolina has taken Simona Halep's place as the player with the easiest overall draw as she's 1.86 percentage points more likely to win the title than would be expected for the 7th best player remaining. On the other hand, Naomi Osaka has the toughest overall draw, but this now belongs to Aryna Sabalenka, as she is 1.55 percentage points less likely to win the title than the 5th best player is expected to. 
  • Ysaline Bonaventure had the easiest 1st round draw, but ended up losing her match against Timea Babos. The player who had the toughest 1st round draw, Anastasia Pavlyuchenkova lost her first round match to Naomi Osaka as expected.
