Sunday's Hangzhou quarterfinal pits Andrey Rublev against Hugo Gaston on hard. Andrey Rublev comes in at 6 wins from the last ten. Hugo Gaston has won 6 of the last 10.

The serve is where this match separates: Rublev has been winning 74.2% of first-serve points to Gaston's 65.9%, and on hard that gap compounds fast. Rublev should have enough here, though Gaston has the tools to make the scoreboard uncomfortable.
