The second day of the 2019 London Diamond League went down on Sunday at London Stadium. A fast women's 5k and the first sub-3:50 mile of the 2019 outdoor season were the highlights at the site of the 2012 Olympic Games.

Women’s 5,000m - Obiri Downs Hassan In Fastest 5k Since 2017

An all-star clash between the hottest distance runner on the planet— mile world record holder Sifan Hassan— and reigning 5,000m world champion Hellen Obiri resulted in the fastest women’s 5k in two seasons as the Kenyan Obiri downed Hassan and countrywoman Agnes Tirop in a meet record of 14:20.36.

The time is the quickest in the world since Obiri herself ran 14:18.37 in June of 2017.

Obiri sat in second behind Hassan at the bell after a 65-second penultimate lap by the Dutch star. Given that Hassan had beaten her soundly three weeks ago in the Prefontaine 3k by nine seconds, there was at least a chance that Obiri was on the ropes as she was tasked with out-kicking a woman who just set the mile world record nine days prior. But sure enough, Obiri went around Hassan with just over 200m to run, sprinting furiously as Tirop also gave close pursuit.

With 100m to run, Hassan was gassed and the gap between Obiri and Tirop was too large to close. Tirop made Obiri earn it all the way to the finish, however, as she ultimately settled for a close second in 14:20.68 PB. Obiri’s last lap was clocked at 62 seconds.

Hassan’s consolation prize in third was a lowering of her European record to 14:22.12.

The race was dominated by Kenyans, as the East African nation occupied eight on the top nine places.

Men’s Emsley Carr Mile - Tefera Survives Wild Early Tactics

For the first time this outdoor season, Samuel Tefera’s aggressive tactics did not cost him the win as the Ethiopian sprinted past Filip Ingebrigtsen in the final straightaway to take the Emsley Carr mile in a world-leading 3:49.45. That’s not to say Tefera didn’t try to spoil his chances.

Once again, the 19-year-old set off at an impossible pace— he split 1:53 through 800m— an ambitious race plan that closely resembled the bold strategies that have jeopardized several of his races this outdoor season. 

In that vein it seemed likely that the indoor 1,500m world record holder would succumb to his own devices when Norway's Filip Ingebrigtsen went past him at the bell at 2:52.25. But this time, Tefera managed to save an extra gear, one he used to wrap around Ingebrigtsen with 120m to go and then outlast him in the final sprint.

Ingebrigtsen settled for second in 3:49.60, the second Norwegian national record in as many days for the Ingebrigtsen brothers. 18-year-old Jakob ran a 13:02.03 5,000m national record on Saturday in London.

Brit Jake Wightman was third in a 3:52.02 personal best.

Women's 100m - Shelly-Ann Fraser-Pryce Continues To Roll In 10.78

Double Olympic champion Shelly-Ann Fraser-Pryce continued her stellar 2019 campaign with her third 10.7 performance of the season, this time a dominant 10.78 victory over Britain’s Dina Asher-Smith in 10.92. Another signature strong start from the 32-year-old Jamaican meant that the race was pretty much over as soon as it had begun, as SAFP was well clear of the field by halfway.

From there Fraser-Pryce only continued to stretch her lead, a comfortable margin that allowed her to cruise across the finish. Sunday’s 10.7 run followed her 10.73 on June 21 in Kingston and her 10.74 on July 5 in Lausanne.
