A spot in the next round is at stake on Friday, when Coleman Wong goes up against Sho Shimabukuro in the Seoul quarterfinal. Coleman Wong comes in at 7 wins from the last ten. Sho Shimabukuro has won 4 of the last 10.

Wong's 74.8% behind the first serve (against 70.9% for Shimabukuro) means break chances should be scarce in one direction. Wong comes in off a compressed schedule; Shimabukuro comes in off a compressed schedule. The edge belongs to Wong — real, but not the kind you take for granted at this level.
