A spot in the next round is at stake on Sunday, when Andrey Rublev goes up against Hugo Gaston in the Hangzhou quarterfinal. Andrey Rublev has won 6 of the last 10. Hugo Gaston comes in at 6 wins from the last ten.
Rublev's 74.2% behind the first serve (against 65.9% for Gaston) means break chances should be scarce in one direction. The edge belongs to Rublev — real, but not the kind you take for granted at this level.
