Earlier October 31 Reporting

Harriet Dart reached her first WTA Tour singles final October 31, recovering from a set down to beat China's Sun Xinran at the Guangzhou Open.

The British qualifier won 5–7, 7–6 (7–1), 6–0 after saving two match points in the second set. The victory sent the 30-year-old into a tour-level singles title match for the first time, 11 years after her tour debut.

Sun, 16, took the opening set after Dart failed to serve it out. The teenager broke Dart three times in that set, taking advantage of a difficult serving start for the Briton.

The second set repeatedly changed direction as breaks of serve were exchanged. Dart faced two match points while serving at 4–5, Tennis Now reported, but survived to force a tie-break. She then allowed Sun only one point in the tie-break, leveling the match.

Dart carried that momentum through the deciding set, which she won without dropping a game. Sky Sports reported that she took 28 of the 41 points played in the third set and completed the victory in a little under two and a half hours.

The result extended a run that began in qualifying. Dart had beaten Tatiana Prozorova and Janice Tjen before overcoming Paula Badosa in the quarterfinals.

Dart entered the semifinal ranked 115th. Her place in the final is secured, but the tournament title remains undecided. Earlier reporting preceded the completion of the other semifinal; the opponent is confirmed in the update above.
