History was made in one of the non-Diamond discipline events during the Diamond League meet in Eugene as 16-year-old Jakob Ingebrigtsen of Norway became the youngest man to run a mile in less than four minutes during the invitational event.
Baker upstages Gatlin and De Grasse
In the men's 100m Justin Gatlin and Andre de Grasse showed they are yet to click into top gear in 2017 and once again missed out on a podium finish with Ronnie Baker taking first place.
Gatlin and De Grasse – two of the men most likely to spoil Usain Bolt's retirement party at the World Championships in London later this year – finished fourth and fifth respectively when the Diamond League kicked off in Doha earlier this month.
And the two swapped places in Eugene on Saturday, as Baker – seventh in Doha – led home China's Su Bingtian and CJ Ujah of Great Britain.
Mo Farah lived up his reputation with victory in the 5000m, while another of the big names in action, American Christian Taylor, beat compatriot Will Claye to triple jump glory.
Bowie wins star-studded 200m
Tori Bowie held off a strong field that included Shaunae Miller-Uibo, Elaine Thompson, Dafne Schippers and Allyson Felix to win the women's 200m, while Caster Semenya triumphed over 800m.
