SNAPSHOT OF ACTION FROM DAY FIVE OF THE WORLD ATHLETICS CHAMPIONSHIPS
Star of the day: South African flyer Wayde van Niekerk locks in the first leg of what would be a rare 200m-400m double by winning the one-lap race in commanding fashion.
Best Australian performance: Twenty-year-old Kurtis Marschall confirms his status as a star of the future with a seventh-placed finish in the men's pole vault.
Upset of the day: Injuries sustained in a fall after she crossed the line to win gold in the women's 100m forced American Tori Bowie to withdraw from the 200m.
Quote of the day: "I'm not just one of the participants any more. I'm not just a spectator out there. I know I can mix it with the big dogs," said Marschall after finishing seventh in the men's vault.
