The 2026 Pan Pacific Open is being played in Tokyo from October 26 to November 1 on hard courts, as a WTA 500 event. The Guangzhou Open is taking place simultaneously in Guangzhou, on hard courts, as a WTA 250 event.
Dart defeated Janice Tjen on October 28 in the round of 16 in Guangzhou, 6-4, 3-6, 6-3, in 2 h 28. The Sun–Timofeeva match page, dated October 29, displayed only 6-3, 0-1 and did not establish a completed victory.
The opponents and level of competition are therefore not reliably comparable for this matchup.
Head-to-head
No direct Sun–Dart head-to-head is documented in the selected sources. The Dart–Qu match on October 1 in Beijing, won by Dart 6-2, 6-7(5), 7-5, was not a direct matchup and does not concern the Pan Pacific Open.
The documented history does not allow a recurring advantage between the two players to be assessed.
