Shericka Jackson's much-anticipated effort to add what would have been a third world record in the women's 200m fell short as her winning time of 21.57, a meeting record, did not threaten the 1988 mark of 21.34 set by the late Florence Griffith-Joyner in winning the Olympic title.

A pulsating day of action at Hayward Field also saw Jacob Ingebrigtsen, who had missed the mile world record by just 0.60sec the previous day, adding another Diamond League trophy to his collection by winning the 3,000m by one-hundredth of a second from Ethiopia’s Yomif Kejelcha.

Tsegay, grimacing but driving onwards, obliterated the world record of 14:05.20 set at this year’s Paris Diamond League meeting by Kenya’s all-conquering Faith Kipyegon, one of three world records this season for the woman who won the world 1500 and 5,000m titles last month.

But now Kipyegon, who won the Diamond League 1500m final yesterday has had her triumphant record trimmed by an athlete who, despite setting a world indoor 1500m record last season, began moving up the distances with a feeling that she would not be able to match the pace of the Kenyan or The Netherlands’ Sifan Hassan.

Running on the Hayward Field track where she won the world 5,000m title last year, Tsegay - who won the world 10,000m title in Budapest - was on a mission, although she was accompanied on it until the final stages by Kenya’s world 5,000m bronze medallist Beatrice Chebet, who finished second in 14:05.92, narrowly outside the old world record.

Within an hour there was another world record to celebrate as Duplantis, who set a men’s pole vault world record of 6.21m at this venue in winning the world title last year, returned in glory to raise that mark to 6.23m - a centimetre higher than he achieved indoors at Clermont-Ferrand in February - at his first attempt.

Electrified, the young Swede bolted off the landing mat into a throng of fellow vaulters who had stayed to watch him before being lifted into the air, as if he were the captain of his own winning team, by home athlete Sam Kendricks, the 2017 and 2019 world champion.

The world and Olympic champion effectively had his hands on the Diamond League trophy after clearing first-time at 6.02m - his third first-time effort - which proved too much for his sole remaining rival, world silver medallist Ernest John Obiena of the Philippines.

But on this occasion, unlike his world record attempt at the last Diamond League meeting in Brussels, Duplantis decided against setting an intermediate height, putting the bar straight up to the new mark.

It worked.

Duplantis has now set seven consecutive world records after adding a centimetre to Renaud Lavillenie’s 2014 mark of 6.16 on February 8, 2020.

How many more centimetres will this 23-year-old add?

Less than 24 hours after running the third fastest mile of all time, 3min 43.73sec, Ingebrigtsen earned a hard-fought victory in the 3,000m.

The 22-year-old Norwegian, who will get married next week, saw his hopes of breaking Daniel Komen’s 1996 world record of 7:20.67 fade by 2,000m, but after holding off the desperate late surge by the Ethiopian who had stalked him from the bell, he was rewarded with a European and Diamond League record of 7:23.63.

Kejelcha was second in a national record of 7:23.64, with home runner Grant Fisher finishing strong to take third place in a North American record of 7:25.47, with Ethiopia’s Telahun Bekele and Olympic 10,000m champion Selemon Barega fourth and fifth in respective personal bests of 7:25.48 and 7:26.28.

Having finally earned the world outdoor title after two successive silvers - at the age of 21 - Ukraine’s Yaroslava Mahuchikh rounded off her season with a Diamond League trophy.

But she was pushed all the way by the Australian who earned Olympic silver ahead of her two years ago, Nicola Olyslagers (nee McDermott), who added a centimetre to her personal best in clearing an Area record of 2.03m but lost on countback.

The Australian responded to Mahuchikh’s first-time clearance of 1.98m by clearing exuberantly at the third attempt and then put the pressure on her rival with a first-time clearance of 2.01m - which was matched.

When the bar went up to 2.03m, the Ukrainian went over at the second attempt to set the 2023 world lead.

But the indefatigable Olyslagers once again cleared at her third attempt to move the competition onto the height of 2.05m which proved too much for both.

The women’s 800m delivered everything hoped of it as home runner Athing Mu, the Olympic champion, edged clear down the home straight from Keely Hodgkinson, lowering her national record to 1min 54.97sec, with the Briton reducing her own national record to 1:55.19.

Natoya Goule-Toppin ran a Jamaican record of 1:55.96 to finish third ahead of Kenya’s weary-looking world champion, Mary Moraa, who clocked 1:57.42.

Kenya’s 19-year-old Emmanuel Wanyonyi, beaten to the world 800m title last month by Canada’s Marco Arop, had his own back in a hugely competitive race as he won in a meeting record and personal best of 1min 42.80sec, the fastest time recorded this year.

Arop was just 0.05sec behind, registering a national record, with Algeria’s Daniel Sedjati third in a personal best of 1:43.06.

Jamaica’s Olympic 110m hurdles champion Hansle Parchment powered through to victory over fast-starting home world champion Grant Holloway, clocking 12.93sec, the fastest run this season and a personal best at the age of 33, with the American fading to second place in 13.06.

The women’s 100m hurdles was won by Nigeria’s Tobi Amusan, who won the world title on this track last year, setting a world record of 12.12 en route to the final and who finished today in a season’s best of 12.33 ahead of Puerto Rico’s Olympic champion Jasmine Camacho-Quinn, who clocked 12.38.

Amusan was provisionally suspended in July for missing three anti-doping controls, but returned to competition last month after a Disciplinary Tribunal found she had not committed an Anti-Doping Rule Violation of three whereabouts failures within a 12-month period.

The Athletics Integrity Unit expressed disappointment with the ruling.

Australia’s Matthew Denny won the men’s discus honours with a last-round national record of 68.43m, overtaking Slovenia’s 2022 world champion and 2023 world silver medallist Kristjan Ceh, who had led with 67.64m.

Denny had already thrown 67.37m, but he had more to come.

Sweden’s Olympic and world champion Daniel Stahl was third on 67.36m.

The women’s discus title went to home Olympic champion Valarie Allman, whose hopes of winning a world title were ended by a final-round effort by fellow American Laulauga Tausaga last month. 

Here, she reversed that order with a best of 68.66m, with the world champion second on 68.36m.

Home shot putter Joe Kovacs, the 2019 world champion, earned victory over his compatriot Ryan Crouser, winner of the last two world titles, by just two centimetres - 22.93m to 22.91m.

World 400m hurdles champion Femke Bol was under pressure for most of her race from home hurdler Shamier Little, the world silver medallist - but the Dutch athlete made her superiority tell over the final two hurdles to win in a meeting record of 51.98sec, with Little second in 53.45.

Swiss decathlete Simon Ehammer - albeit concentrating on the long jump this season because of a shoulder injury - added another feather to his hat as he beat a field of men’s long jump specialists with a best of 8.22m, winning by virtue of a better second-best effort from Jamaica’s 2019 world champion and 2023 bronze medallist Tajay Gayle.

Serbia’s world champion Ivana Vuleta won the women’s long jump with a last-round effort of 6.85m which equalled the lead of Nigeria’s Ese Brume and earned her the Diamond League trophy through a better second-best effort.

In the absence of the three-time world champion Noah Lyles, the men’s 200m appeared wide open - and, surprisingly, Canada’s Olympic champion Andre De Grasse, who was fifth in the world final after a relatively muted season, came through to win assuredly in 19.76sec, a season’s best.
