Rain has stalled Ashleigh Barty’s bid to secure a place in the world’s top 10.
Barty was leading world No.2 Petra Kvitova 2-1, with games on serve, when their quarter-final at the WTA’s Miami Open was suspended on Tuesday night.
A maiden win over Kvitova would ensure Barty would crack the top 10 for the first time.
Earlier, Anett Kontaveit brought Hsieh Su-wei’s giant-killing run to a dramatic end with a comeback win to become the first player through to the semi-finals.
The 33-year-old Hsieh, having beaten Japan’s world No.1 Naomi Osaka in the third round and 13th seed Caroline Wozniacki in the fourth, looked poised to add the 21st-seeded Estonian to her list by racing to a 4-0 lead in the third set.
But Kontaveit, 10 years her junior, took a page from the Taiwanese player’s own playbook and dug in to prevail 3-6 6-2 7-5.
“I was so close to being out of there so many times,” Kontaveit said.
“I just tried to keep fighting and trying to stay in there and try and still be aggressive somehow.
“I was trying to think more about what I have to do than about the score.”
The Estonian awaits the winner of the Barty-Kvitova match.
In her third-round win over Osaka, 27th seed Hsieh rallied from a set and break down but this time the tables were turned.
Kontaveit bravely battled back to get on level terms and, with Hsieh serving at 6-5 to force a tiebreak, moved in for the kill, breaking the tiring Taiwanese to clinch a stirring win.
“Today probably wasn’t the best match that I have ever played but I’m so happy to be through that,” said Kontaveit. “I feel like I fought really well and I never gave up.”
