Edoardo Scotti’s 45.21-second run in the 400m at the Wanda Diamond League meeting in Rome last year was more than just a PB.
USA’s mixed 4x400m world record of 3:09.34 and Yaroslava Mahuchikh’s world U20 indoor high jump records of 2.01m and 2.02m have been ratified.
Returning to their vintage best, the USA regained the men’s 4x400m world title with the fastest time for 11 years with a typically dominant performance.
Living to their favourite’s billing, the US squad dominated the women's 4x400m relay, blitzing the field with a 3:18.92 world-leading performance.
Report: mixed 4x400m relay triple jump - IAAF World Athletics Championships Doha 2019
The first world record of the IAAF World Athletics Championships Doha 2019 came just half way through the second session of competition as USA won their heat of the mixed 4x400m on Saturday (28).
After relinquishing their world crown at the World Championships in London to Trinidad and Tobago two years ago, the USA will be desperate to regain the men’s 4x400m title they have long viewed as their property.
Two years ago, a US quartet demoralised the field in the women's 4x400m, winning by nearly six seconds in a world-leading 3:19.02, the fastest time in the world since the 2012 Olympic Games held on the same London Stadium track. That performance produced, by far, the largest winning margin in the event at a World Championships. Although they may not be fielding as powerful a squad this time around, the USA still arrives in the Qatari capital poised to win a ninth title in the event.
One thing that can be certainly said of the mixed 4x400m relay: nothing about it is certain.
Sprinter Matthew Boling confirmed his status as a rising star of the sport as he led the USA to two world U20 relay records* while the US 4x400m women added one more to provide a sensational finale to the 20th Pan American U20 Championships, held at San Jose’s National Stadium in Costa Rica on 19-21 July.
