Ukrainian high jumper Yaroslava Mahuchikh and Ireland’s 1500 metres runner Ciara Mageean produced outstanding performances at the Wanda Diamond League meeting in Brussels tonight.

Mahuchikh equalled the Ukrainian record of 2.05 metres, topping this year’s world list, while Mageean set an Irish record of 3min 56.63sec in beating the British runner behind whom she has taken Commonwealth and European silver this summer, Laura Muir.

Mahuchikh, the 22-year-old Ukrainian, who fled Russian bombardment in March this year before earning world indoor gold, saw off the challenge of the Australian who beat her to the world outdoor title in Eugene two months ago, Eleanor Patterson, with a first-time clearance of 1.97m.

After failing at 2.00m and moving on, the newly established European champion cleared 2.02m first time and 2.05m - one centimetre below her indoor best and equalling the 1995 mark set by Inga Babakova - at the second attempt before having three unsuccessful attempts at a world record of 2.10m.

Mageean, who concentrated her attention on her Scottish rival in the Commonwealth and European finals without being able to outrun her in the closing stages, earned a different result at the Allianz Van Damme Memorial meeting in a photo-finish conclusion to a stunning race that saw seven women go under four minutes.

Muir clocked 3:56.86 in second place, with Ethiopians Freweyni Hailu and Diribe Welteji third and fourth in 3:56.94 and 3:57.82 respectively.

The concluding race, a stacked men’s 800 metres, saw another runner who has appeared in a Scottish vest this season, world 1500m champion Jake Wightman, lower his personal best to 1:43.65 just a couple of weeks after earning European silver at the distance.

Wightman thus beat the Scottish record of 1:43.88 set by Tom McKean in 1989 - something he had spoken about trying to do before he competed at the European Championships in Munich last month.

Algeria’s Djamel Sedjati was second in 1:44.12, with Kenya’s world and Olympic champion Emmanuel Korir third in the same time and Spain’s Mariano Garcia, who beat Wightman to European gold, seventh in 1:44.86.

A day after getting a semi-serious 100m challenge proposed by the five-times women’s world champion Shelly-Ann Fraser-Pryce of Jamaica - a challenge that could well happen in Brussels next year - Mondo Duplantis continued to find life a little perplexing as he experienced a rare defeat in his better discipline of the pole vault.

Sweden’s 22-year-old Olympic and world champion, who improved his world record to 6.21 metres in July, could only manage 5.81m on the night, with Ernest Obiena of The Philippines earning a landmark victory as he cleared 5.91m at the third attempt.

Cuba continued to rule the men’s triple jump as Lazaro Martinez recorded 17.49m ahead of Burkino Faso’s Hugues Zango, who had a best of 17.40m, while multiple world and Olympic champion Christian Taylor of the United States, still recovering full fitness after rupturing his Achilles tendon last year, had a season’s best of 16.72m.

Meanwhile Fraser-Pryce also experienced the unfamiliar feeling of defeat as her time of 10.74 secs in the women's 100m was bettered by fellow Jamaican Shericka Jackson, the world 200m champion, who ran 10.73.

Elsewhere in the penultimate Diamond League meeting before next week’s two-day final in Zurich, Kara Winger won the women’s javelin in a United States and meeting record of 68.11m.

It has been a special year for the 36-year-old from Seattle, who won world silver in Eugene this summer.

The 100m hurdles saw another huge marker laid down by the Olympic champion, Jasmine Camacho-Quinn of Puerto Rico, who recently beat Nigeria’s newly established world champion and record holder Tobi Amusan, as she won in a meeting record of 12.27.

Jacob Krop of Kenya needed a 5,000m personal best and 2022 world leading performance of 12:45.71 to beat the United States champion Greg Fisher, second in an area record of 12:46.96, with former refugee athlete Dominic Lobalu finishing fourth in a South Sudan record of 12:52.15.

Fiordaliza Cofil of the Dominican Republic won the women’s 400m in a personal best of 49.80 ahead of the Commonwealth champion from Barbados, Sada Williams, who clocked 50.15.

Brazil’s world men’s 400m hurdles champion Alison dos Santos earned victory in 47.54, while a personal best of 9:02.43 earned Kenya’s Jackline Chepkoech victory in the women’s 3,000m steeplechase.

Erriyon Knighton, the 18-year-old world 200m bronze medallist from the United States, earned men's 200m victory in 20.07.

Earlier in the evening Joe Kovacs, the 2019 world shot put champion from the United States, won in a meeting record of 22.61.
