Australian pair Kim Mickle and Kathryn Mitchell both took care of business in being automatic qualifiers for Sunday’s women’s javelin final.
A personal best of 65.73 metres saw Mickle through, moving her to second on the Australian all-time list behind 1996 Olympic silver medallist Louise McPaul-Currey.
London Olympic finalist Mitchell threw 62.80m with her second attempt, enough to book her passage to the final.
Russia’s defending world champion Maria Abakumova landed a throw of 69.09m to head up qualifying.
Mickle placed sixth in Daegu but performed below par to miss the Olympic final 12 months ago.
She has been a model of consistency this year with podium finishes at four Diamond League meets.
The Perth-based Mickle intends to release her “boom tactic” in the final, which she describes as simply going out to “just smash it”.
“I have two points that I think of and I was thinking of those two points then,” she said.
“‘Boom’ is don’t think about those two points, just go for it.”
Mitchell says it means a lot to repeat her effort from London in making the final after undergoing ankle surgery in February.
“I didn’t start competing until quite late in the season and then I started in Europe,” she said.
“Competition by competition I’ve just built up bit by little bit.”
Joshua Ross did not fare as well as his Australian team-mates, running 21.45 to be seventh in his first-round heat of the 200m.
Usain Bolt strolled through to win his opening preliminary in 20.66, while Briton Adam Gemili was the fastest through with 20.17.
