A spot in the next round is at stake on Saturday, when Daniil Medvedev goes up against Valentin Royer in the Hangzhou round of 16. Daniil Medvedev is 5-5 across recent matches. Valentin Royer has won 7 of the last 10.

The serve is where this match separates: Medvedev has been winning 72.8% of first-serve points to Royer's 26.2%, and on hard that gap compounds fast. Anything other than a Medvedev win would rank among the bigger surprises of the week.
