Friday's Seoul quarterfinal pits Seong Chan Hong against Terence Atmane on hard. Terence Atmane comes in at 5 wins from the last ten. Seong Chan Hong comes in at 7 wins from the last ten.

The serve is where this match separates: Atmane has been winning 72.8% of first-serve points to Hong's 66.2%, and on hard that gap compounds fast. Hong comes in off a compressed schedule. Atmane should have enough here, though Hong has the tools to make the scoreboard uncomfortable.
