Recent form
The confirmed tournament is the 2026 Toray Pan Pacific Open, a WTA 500 event in Tokyo, played outdoors on hard courts from October 26 to November 1, with a 28-player singles draw. Shi Han is listed as world No. 162 and Dayana Yastremska as No. 97; Yastremska therefore has the better published ranking, without this confirming their participation or form in this tournament.
Shi Han defeated Alexandra Eala in Wuhan on October 12, 2026, 4–6, 6–3, 6–3, but that result concerns a different opponent and a different competition.
Head-to-head
No confirmed head-to-head encounter between Shi Han and Dayana Yastremska has been established. No previous match by either player in this Tokyo edition is verifiable in the official documents consulted; therefore, there is no documented recent series enabling a reliable comparison.
Line-up and availability
The exact players are identified, but the matchup is not confirmed in the official order of play for October 28, which lists eight second-round singles matches without this pairing. The draw, round, court, and exact match type remain to be confirmed.
Market reading
Prediction: Dayana Yastremska · Match winner. Estimated probability: 62 %, based on market odds. No stake: this probability does not justify a bet at the available odds.
