Recent form
Timofeeva is officially listed as the No. 7 seed in Guangzhou, on outdoor hard court, but her purported match against Teodora Kostovic on October 26 is not confirmed by an open official score. Sun is associated with a match against Mananchaya Sawangkaew on October 27, reported as postponed/suspended without a fully verifiable score.
She had lost to Coco Gauff in Beijing on October 5, 2026, 7-5, 6-1, but this result does not directly measure her current form against Timofeeva. Recent serving, returning, effort-duration, and match-load statistics have not been established.
Head-to-head
No relevant and verifiable head-to-head between Timofeeva and Sun has been confirmed. Any possible earlier meeting cannot be equated with this matchup or used as a predictive basis.
The only recently documented result concerning Sun is her loss to Coco Gauff in Beijing on October 5, 2026, 7-5, 6-1, in 1 h 29.
Line-up and availability
This is a women's singles match. The tournament officially identified as the Pan Pacific Open is the Tokyo tournament, a WTA 500 event on outdoor hard court, from October 26 to November 1, 2026, with a 28-player singles draw.
Timofeeva and Sun do not appear on the visible list of participants. The matchup more likely corresponds to the 2026 Guangzhou Open, a WTA 250 event on outdoor hard court, but the exact round and schedule remain to be confirmed.
