A spot in the next round is at stake on Friday, when Ann Li goes up against Elena Rybakina in the Toronto round of 32. Elena Rybakina comes in at 6 wins from the last ten. Ann Li is 5-5 across recent matches.
The serve is where this match separates: Rybakina has been winning 70.1% of first-serve points to Li's 65.2%, and on hard that gap compounds fast. If Rybakina plays anywhere close to a normal level, this ends in relatively comfortable fashion.
