Dafne Schippers returned to form with a European best over 150m at the Golden Spike meeting with Karsten Warholm left bemused by his failure to get close to Kevin Young's 28-year-old mark.
Dafne Schippers returned to form in style at Ostrava's Golden Spike meeting on Tuesday (8 September).
The two-time world 200m champion clashed with the year's sensation over 100m, Switzerland's Ajla Del Ponte, over 150m.
And the Dutchwoman showed signs of coming back to her very best with a superb bend on her way to clocking 16.56s with Del Ponte in second.
Cote d'Ivoire's Marie-Josee Ta Lou was back in fifth place.
The scene was set for Karsten Warholm to break the 400m hurdles world record but a stuttering approach to the penultimate hurdle saw him finish well down on his European record set in Stockholm two weeks ago.
And Olympic champion Ryan Crouser kept up his stellar form with another 22m-plus throw securing him the men's shot put.
On a track with a reputation for fast times, Femke Bol recorded the second quickest 300m hurdles in history in her first try at the distance.
The Dutchwoman already had the fastest 400m hurdles of 2020, and she crossed the line in 38.55s well clear of Slovakia's Emma Zapletalova.
Zuzana Hejnova, who set the world best of 38.16s in 2013, was down in sixth place.
Warholm signalled his excitement and intent with a roar as he was introduced to the crowd.
After a typically explosive start from his favoured lane eight, the two-time reigning world champion did not see another rival with the clock as his only opponent.
A slight stutter approaching the penultimate barrier did not appear to cost too much time but he appeared somewhat bemused to see his winning time of 47.62s, almost a second down on his best.
France's Ludvy Vaillant chased him home, over one and a half seconds adrift.
Jakob Ingebrigtsen's late decision to run in Ostrava proved to be a good one as he took the 1500m.
Warholm's fellow Norwegian always looked in control at the front as he held off Kenya's Kumari Taki and Stewart McSweyn of Australia to claim victory in 3:33.92.
Jake Wightman produced a power-packed finish to win the 800m.
The 26-year-old moved out to lane three to make his challenge in the home straight and was rewarded with a personal best of 1:44.18.
Andreas Kramer was second in a new Swedish record ahead of Bosnia's two-time World Championship medallist Amel Tuka.
Wightman's fellow Scot Laura Muir showed her versatility with a commanding win in the 800m.
The European 1500m champion tracked the pacemaker and kicked clear with 250m to go on her way to a season's best 1:58.84.
Battle was engaged with half a lap to go but the Kenyan - running her first 1500m of 2020 after two victories over 1000m - unleashed a powerful kick to which the young Scot had no response.
She won in 3:59.05 with Laura Weightman passing Reekie for second place.
Christian Taylor left it late to claim a thrilling triple jump.
Stockholm winner Hugues Fabrice Zango had led with 17.42m going into the final round, but the double Olympic gold medallist and four-time world champion produced a leap of 17.46m - the longest jump in the world this year - to take victory.
Ryan Crouser made it six wins out of six with another authoritative display in the shot put.
The Rio 2016 champion hurled the metal ball out to 22.43m with Randy Barnes' 1990 world record of 23.12m eluding him for another day.
Ernest John Obiena of the Philippines sprung a surprise in a star-studded pole vault
Britain's Holly Bradshaw won the women's event with a second-time clearance of 4.60m.
And there was joy for the home fans as two-time Olympic champion Barbora Spotakova took the javelin with a season's best 65.19m.
