Australia's Brittany Elmslie has surged past two Olympic champions to claim 100m freestyle gold at the world short course titles in Canada.
Nerves were not a problem for Brittany Elmslie, who surged past two Olympic champions to claim 100m freestyle world short course titles gold in Canada for a depleted Australia.
Elmslie on Friday was under enough pressure stepping up in the absence of the Campbell sisters and Rio Olympic golden girl Emma McKeon after they were among a string of big names to opt out of the six-day world titles at Windsor.
Then she saw her opposition on the starting blocks.
Lining up beside her were not one but two Olympic 100m freestyle champions - the Netherlands' 2012 victor Ranomi Kromowidjojo and joint Rio winner and hometown favourite Penny Oleksiak of Canada.
Yet Elmslie - a two-time Olympic relay gold medallist - stormed home to clinch Australia's second gold of the meet and relegate her famous rivals to the minor medals.
Elmslie clocked a personal best 51.81 seconds, placing her fifth on the Australian all-time list.
"It's bit weird to get an individual title, especially in short course - it's not normally one of my strengths," Elmslie said.
Elmslie said racing in Australia had ensured she was unfazed by the quality field on the blocks.
"Coming from Australia with such big depth in our 100m freestyle every time I get up to race I am racing Cate, Bronte (Campbell) and Emma (McKeon) so it's not really any different I guess," she said.
"It doesn't really overwhelm me that much."
Elmslie's triumph marked Australia's second gold after Mitch Larkin defended his 100m backstroke crown on Thursday (AEDT).
Day three also featured three bronze for Australia - Emily Seebohm (200m backstroke), David Morgan (100m butterfly) and Kiah Melverton (800m freestyle).
At the halfway mark of the meet, Australia have a total haul of two gold and four bronze.
A day after being pipped for 100m backstroke bronze, triple Olympian Seebohm fought back from sixth with 50m left to finish third in the 200m backstroke final.
Seebohm - who has a nine event program - also qualified third fastest for the 100m individual medley final on Saturday.
Rio Olympian Morgan set a new Oceania and Australian record to clinch 100m butterfly bronze.
He took 0.20 of a second off Mitchell Patterson's 2009 Australian mark of 49.51.
South Africa's Chad Le Clos won in a new world record of 48.08.
Melverton held out compatriot Ariarne Titmus to claim 800m bronze in a personal best time (eight minutes, 8:16.51 seconds).
