Thursday's Singapore round of 16 pits Maria Sakkari against Nao Hibino on hard. Maria Sakkari is 6-4 across recent matches. Nao Hibino comes in at 5 wins from the last ten.

The serve is where this match separates: Sakkari has been winning 65% of first-serve points to Hibino's 61.4%, and on hard that gap compounds fast. Anything other than a Sakkari win would rank among the bigger surprises of the week.
