Elina Svitolina eventually claimed the Malaysian Open title on Sunday following a hugely dramatic, rain-interrupted final with Eugenie Bouchard in Kuala Lumpur.
Bouchard served for the championship after breaking to claim a 5-4 lead in the third set of a match that was delayed on several occasions by showers.
However, the Canadian was broken to love as she sought to wrap up victory and world number 19 Svitolina - who had twice fallen a break down in set two after losing the opener - won the next two games to prevail 6-7 (5-7) 6-4 7-5 after almost three hours on court.
Svitolina's hopes of claiming a fourth WTA title looked to be in tatters when she reacted emotionally to losing the first set and then dropped serve at the start of the second.
However, Bouchard gave up the initiative from 2-0 and 4-2 up, ultimately losing four games in a row as second seed Svitolina pulled level.
Bouchard received treatment on an apparent neck problem before further breaks were exchanged prior to a lengthy stoppage midway through the decider.
Svitolina found herself behind once more when play finally resumed, but was not to be denied a fourth win from as many WTA Tour meetings with Bouchard.
The match finished just before midnight local time and, in an on-court victory speech, Svitolina said: "Thank you very much for staying that late to watch our final. I want to thank Genie for a great final, it was a really tough one."
