Britain's Harriet Dart saved three match points to stun third seed Camila Giorgi at the Nottingham Open and reach her first WTA quarter-final.
The match was tied at a set apiece before rain stopped play on Wednesday, and the two had a lengthy wait to go on court on Thursday.
However, Dart produced a superb tie-break performance to beat the 26th-ranked Italian 5-7 6-4 7-6 (7-3).
"I can't quite believe it, especially saving those match points," Dart said.
The 25-year-old, ranked 114 in the world, will face sixth seed Alison Riske of America next.
Dart slipped to 0-40 down on her serve with Giorgi leading 5-4, but managed to find a way through before dominating the tie-break.
