Usain Bolt further boosted his legacy by winning the 200-meter final in emphatic fashion at the World Championships in Athletics in Moscow.
It was a seventh world gold medal for the Jamaican to add to his six Olympic titles.
The 26-year-old can take his career gold tally to 14 on the final day of action at the Luzhniki Stadium in the 4x100-meter sprint relay.
Bolt clocked a time of 19.66 seconds and eased down toward the line as he comfortably defeated compatriot Warren Weir (19.79), who took bronze at the 2012 London Olympics.
American Curtis Mitchell (20.04) denied Jamaica a clean sweep with a late lunge to take third away from Nickel Ashmeade (20.05). British teenager Adam Gemili faded in the final 30 meters and was fifth in 20.08.
It meant Bolt completed another brilliant sprint double—having won the 100-meter dash last weekend—and it was a fourth sprint gold medal in Russia for the dominant Jamaicans after Shelly-Ann Fraser-Pryce completed the women's 100 and 200 double.
The winning time was well outside Bolt's own world record of 19.19 set at the world championships in Berlin four years ago.
The only time Bolt has failed to take gold since 2009 was when he false-started in the 100-meter final at this event two years ago in Daegu.
That allowed compatriot Yohan Blake to take gold, but the Olympic silver medalist plus Walter Dix and Christophe Lemaitre (second and third in Korea in 2011) were all missing from the final due to injuries.
Tyson Gay and Asafa Powell were also not in the mix after failing drug tests, while 100-meter silver medalist Justin Gatlin did not compete.
However, that takes nothing away from Bolt, who continues to enhance his status as one of the sport's all-time legends.
Ethiopia's Meseret Defar also underlined her reputation by adding a second world gold to her two Olympic titles in the women's 5000-meters.
However, one woman who was unable to defend her title was Australia's Sally Pearson, as the Olympic champion was edged out by Brianna Rollins of the USA in the 100-meter hurdles. Britain's Tiffany Porter was third.
The biggest cheers of the week came as Russia's women won the 4x400-meter relay ahead of the USA and Great Britain, and then local favorite Svetlana Shkolina won the high jump.
