No recent headlines matched this market. We only show an article when the names in the question appear in its headline, so a very local or very new market often has nothing. Showing nothing is deliberate: an unrelated story here would read like evidence about the price.

Headlines are matched on the names in “Set Handicap: Back (-1.5) vs Yamaguchi (+1.5)”. Nobody checks them by hand, so one may not be relevant. They also say nothing about whether the price has already moved on this news.

How this market resolves

This market refers to the tennis match between Dayeon Back and Mei Yamaguchi in the W75 Tianjin, originally scheduled for August 31, 2026 at 10:00PM ET. This market will resolve to "Back" if Dayeon Back wins by 2 or more sets than Mei Yamaguchi, based on the final completed score. Otherwise, it will resolve to "Yamaguchi." If the match begins but is not completed due to retirement, default, or disqualification, this market will resolve 50-50, unless the outcome of this market has already been unconditionally determined by the completed portion of play. For example, if the deciding set has begun when the match ends, Dayeon Back can no longer win by 2 or more sets, and this market will resolve to "Yamaguchi." If the match is canceled before play begins, or a result has not been determined by September 14, 2026, 11:59 PM ET (14 days after the scheduled start), this market will resolve 50-50. Resolution will be based on official ITF results.
