A spot in the next round is at stake on Friday, when Elena Rybakina goes up against Leylah Fernandez in the Tokyo quarterfinal. Elena Rybakina brings a 3-match winning streak into this one, 9-1 across the last ten. Leylah Fernandez has won 7 of the last 10.

Rybakina's 70% behind the first serve (against 64.7% for Fernandez) means break chances should be scarce in one direction. If Rybakina plays anywhere close to a normal level, this ends in relatively comfortable fashion.
