Kenyan's Javelin glory
Kenya's Julius Yego proved his nation doesn't just produce world-beating runners when taking victory in the men's javelin at the World Championships, his winning throw of 92.72m the longest in 14 years.
Yego produced his winning effort in the third round, and a stacked field couldn't get near his whopping mark thereafter, with silver medallist Ihab Abdelrahman El Sayed of Egypt managing a best of 88.99m.
In the men's 400m final, another star of the summer, South Africa's Wayde Van Niekerk, sprang an upset, the 23-year-old blasting through the first 200m and building a huge lead by the time he turned for home.
Van Niekerk reached the finish in 43.48 seconds, the sixth fastest time in history, and had to be stretchered off the track afterwards. Lashawn Merritt was second in 43.65, with Olympic champion Kirani James third.
"I am not surprised by the amazing times," said James. "I know what those guys are capable of."
The women's 400m hurdles title was successfully defended by the Czech Republic's Zuzana Hejnova, who ran a world-leading time of 53.50 with Shamier Little of the USA second.
The women's 3,000m steeplechase title was won by Kenya's Hyvin Jepkemoi in 9:19.11, while Cuba's Yarislav Silva took the women's pole vault with a best clearance of 4.90m.
