Ethiopia's 10,000m world champion Gudaf Tsegay shattered the women's 5,000m world record on Sunday, winning the Diamond League finals at Eugene, Oregon in 14min 00.21sec.

The 26-year-old Tsegay carved almost five seconds off the previous record of 14:05.20 set by Kenyan Faith Kipyegon in Paris on June 9.

Kenyan Beatrice Chebet was second to Tsegay in 14:05.92, the third-fastest time ever.

In other early action Sunday, Emmanuel Wanyonyi clocked a world-leading 1min 42.80sec to edge Marco Arop -- the man who beat him to World Championships gold last month -- in the 800m.

It marked the second time in two weeks that Kenya's Wanyonyi had gotten the better of the Canadian world champion after his victory at Xiamen on September 2 in a then world-leading 1:43.20.

Arop led much of the way but couldn't hold off Wanyonyi at the line and settled for second in a Canadian record of 1:42.85.

Yaroslava Mahuchikh edged Nicola Olyslagers in the women's high jump, both clearing 2.03m to improve on the world lead of 2.02 they shared coming into the meeting.

Femke Bol cruised to victory in the women's 400m hurdles in 51.98sec. American Shamier Little was second in 53.45 and Rushell Clayton was third in 53.56.
