Olympic champions Noah Lyles and Julien Alfred stormed to statement victories in the Diamond League Final on Thursday, two weeks before the world championships in Tokyo.
American Lyles became the first track athlete to win six Diamond League Final titles by beating Letsile Tebogo of Botswana in the 200 meters, and St Lucia's Alfred put injury concerns behind her with a dominant win in the women's 100.
Lyles, a three-time world 200 champion, trailed Tebogo coming off the corner before reeling in his rival to cross the line in 19.74 seconds to win by 0.02 seconds.
