Sunday's Shanghai round of 32 pits Hubert Hurkacz against Yi Zhou on hard. Hubert Hurkacz brings a 5-match winning streak into this one, 9-1 across the last ten. Yi Zhou has won 5 of the last 10.
The serve is where this match separates: Hurkacz has been winning 75.9% of first-serve points to Zhou's 71.7%, and on hard that gap compounds fast. Anything other than a Hurkacz win would rank among the bigger surprises of the week.
