Marie-Josee Ta Lou of the Ivory Coast and Britain’s Dina Asher-Smith flourished in the women’s 60 metres as double Olympic gold medallist Elaine Thompson and two-time world 200m champion Dafne Schippers fell off the pace at the Muller Indoor Grand Prix at the Emirates Arena in Glasgow.
In what was the final event in this season’s International Association of Athletics Federations (IAAF) World Indoor Tour - and effectively a dress rehearsal for the IAAF World Indoor Championships due to start in Birmingham on Thursday (March 1) – Ta Lou, 100 and 200m silver medallist at last year's World Championships in London, warmed up with victory in a stadium record of 7.07sec, finishing 0.02 seconds clear of Britain’s European 200m champion.
Thompson, like Schippers had failed to shine in the heats, was third in 7.12, with the Dutch athlete a distant fifth in 7.22.
In the men’s 60m, China’s Su Bingtian, who has ruled in Europe this season, maintained business as usual as he secured overall IAAF World Indoor Tour victory in the event in 6.50, equalling the Scottish all-comers’ record.
Mike Rodgers of the United States was second, 0.04 seconds behind.
Christina Manning won the women’s 60m hurdles in a stadium record of 7.79, with her constant rival, fellow US athlete Sharika Nelvis, second in 7.84.
That left the two athletes tied on points in the IAAF World Indoor Tour standings – and thus requiring a tie-break.
Manning, who owns the best performance of the duo from the IAAF World Indoor Tour races, was duly announced the winner of the $20,000 (£14,00/€16,276) bonus and a wild card for the impending World Indoor Championships.
"I came out here for the win," said Manning.
"I needed the win to claim the tour title and I got it..
“I’m just going for a medal [at the World Indoor Championships]."
The men’s 60m hurdles was won by an athlete who had never competed indoors before.
A clear victory in 7.49 will send Jamaica’s Ronald Levy on to Birmingham 2018 with realistic medal ambitions.
Levy had a 0.09 seconds winning margin over America's 110m hurdles world record holder, Aries Merritt.
Britain’s European indoor champion Andrew Pozzi, undefeated at 60m hurdles since 2014, had to settle for third in 7.60.
Just one point separated Serbia's Ivana Španović and Germany'sSosthene Moguenara in the IAAF World Indoor Tour long jump standings ahead of Glasgow.
Moguenara finished ahead of Španović to take the series victory, but they were both upstaged by Sweden’s Khaddi Sagnia.
The 23-year-old flew out to an outright lifetime best of 6.92 metres with her first leap of the competition, equalling the Swedish indoor record set by heptathlon legend Carolina Kluft in 2004 and breaking the Scottish all-comers’ record.
After missing out on a World Indoor Championships team spot at the recent US Indoor Championships, 400m runner Fred Kerley may have felt that he had something to prove in Glasgow.
This time he ensured he got to the break first, going through 200m in 21.95, and then maintained his lead to the end.
Kerley crossed the line in a stadium record of 45.86, winning comfortably from Slovenia’s Luka Janežič, who clocked 46.29.
Kenya’s Beatrice Chepkoech knew that a strong performance in Glasgow could elevate her to the top of the women’s 1500m IAAF World Indoor Tour standings.
The steeplechase specialist crossed the line first in 4min 02.21sec to take two seconds off the Kenyan indoor record she set earlier this year.
Britain’s Tom Bosworth took more than a second off the world best in the 3,000m race walk as he crossed in 10 30.28.
"I can’t believe it," said Bosworth, who had to concentrate over the final stages of the race after getting two red cards.
"I’m over the moon to get a world record but I feel sick after that.”
Kenyan teenager Justus Soget was a surprise winner in a men’s 3,000m containing world indoor champion Yomif Kejelcha of Ethiopia and America's Olympic 5000m silver medallist Paul Chelimo,
Soget stole victory on the line from Chelimo by one hundredth, clocking a Scottish all-comers’ record of 7:39.09.
Kejelcha finished third in 7:39.36 and, in doing so, won the IAAF World Indoor Tour.
Poland’s three-times European 800m champion Adam Kszczot - who had already done enough before Glasgow to secure the IAAF World Indoor Tour title - won in 1:47.15 ahead of compatriot Marcin Lewandowski, who clocked 1:47.50, and Britain’s Jake Wightman, who finished in 1:47.69.
Greek pole vaulter Ekaterini Stefanidi owns one of the longest active winning streaks in athletics, but it came under serious threat from compatriot Nikoleta Kiriakopoulou before she made the clearance of 4.75m she needed on her third and final attempt.
Stefanidi was not the only world champion to extend a winning streak.
Russia's Maria Lasitskene, competing as an Authorised Neutral Athlete, won the high jump with customary ease, enjoying first-time clearances up to and including 1.95m.
China’s Shi Yuhao left it late to take the lead in the men’s long jump.
The recently-crowned Asian indoor champion sailed out to 8.13m, the only eight-metre jump of the competition, to move from fifth to first in the final round.
Elsewhere, America's Phyllis Francis showed the same finishing strength that carried her to the world title last year, winning the 400m in 52.00.
