Naomi Osaka enters this Pan Pacific Open round-of-16 clash as the clear favorite, bolstered by her status as a four-time Grand Slam champion and former world No. 1, plus strong home support at Tokyo's Ariake Coliseum where she won the title in 2019. Fresh off a straight-sets victory over Jasmine Paolini that included saving multiple set points, the No. 7 seed has demonstrated effective serving and composure on hard courts. Mia Pohankova, an 18-year-old wild card ranked No. 144, arrives with momentum after a dominant first-round win and a rapid ranking climb, but faces her most significant test yet against an opponent with far greater experience and a superior head-to-head edge in main-draw play.
This market refers to the tennis match between Naomi Osaka and Mia Pohankova in the Pan Pacific Open, originally scheduled for October 27, 2026 at 10:00PM ET. This market will resolve to "Over" if the total number of games completed in the first set equals or exceeds 9. Otherwise, it will resolve to "Under." Any first-set tiebreak counts as one (1) game. If the match is postponed or suspended, this market will remain open until the first set has been completed. A postponement alone will not trigger a 50-50 resolution. If the match is permanently abandoned before the first set is completed, or if the first set has not been completed by November 10, 2026, 11:59 PM ET, this market will resolve 50-50, unless the outcome has already been unconditionally determined based on completed play. An outcome is considered unconditionally determined if it would have been guaranteed under every possible completion of the set played according to the match format published by the tournament organizer for that round, including whether the set is decided by a tiebreak. For example, for a line of 9.5, if play stops with the first set at 5-4, completing the set would have required at least 1 additional game, resulting in at least 10 games played, so "Over" would resolve as the winning outcome. The primary resolution source for this market will be official WTA statistics; however, a consensus of credible reporting may also be used. This market may resolve only when the listed period of play has concluded and the result can be definitively determined by the listed resolution source(s).
