In so doing Echevarria, who failed to reach last year's outdoor World Championship final, overtook, for the second time the South African who took that world gold in London, Luvo Manyonga.

This time Manyonga had to settle for silver in an area record of 8.44m.

Defending champion Marquis Dendy of the United States joined this extraordinary party late with a fifth-round effort of 8.42m that earned him bronze.

As he commiserated with his team-mate Jarrion Lawson, whose 8.14m had not even got him onto the podium, he could be heard to say: "I can't believe it, 8.42m and I got beat."

The three other golds on the night went to Murielle Ahoure of the Ivory Coast, who won the women's 60m in a 2017 world-leading time of 6.97sec, Britain's Katarina Johnson-Thompson, who took the pentathlon title, and Anita Marton of Hungary who won the women's shot put with 19.62m.

Manyonga, who missed the Rio 2016 title by a single centimetre before claiming global gold last summer, had started with two fouled jumps that were nevertheless so huge that he seemed in danger of landing beyond the end of the pit.

He remained relaxed, despite the fact that he needed to record a mark on his third attempt in order to remain in the running, and duly produced a relatively conservative effort of 8.33m that nevertheless looked a potentially winning mark.

But Echevarria, whose second round of 8.28m had equalled his best, responded immediately with an effort of 8.36m.

Game on - and Manyonga, still grinning, was game, responding in turn with a fourth round leap of 8.44m.

Astonishingly, the young Cuban had one more move to make as he reached 8.46m in round five, and try as he might, the South African could not produce a legal response to better it.

In spirit, this final replicated the gripping contest of the previous evening in which 20-year-old Russian high jumper Danil Lysenko, competing as an Authorised Neutral Athlete, reversed the result of last summer's World Outdoor Championships to defeat Qatar's Mutaz Essa Barshim.

Both rivalries promise future marvels at global level in the next few years.

Ahoure was the form runner of a final stacked with talent, finishing just ahead of compatriot Marie-Josee Ta Lou, double silver medallist at last year's Outdoor World Championships in London, who clocked a personal best of 7.05.

Bronze went, surprisingly, to Switzerland's Mujinga Kambundji in 7.05 as she finished ahead of the Rio 2016 100 and 200m champion Elaine Thompson of Jamaica, fourth in 7.08, and double world 200m champion Dafne Schippers of The Netherlands, fifth in 7.10.

Britain's 25-year-old Johnson-Thompson won the European indoor pentathlon title with a score of 5,000 points in 2015, but her career has not run smoothly since.

Her failure to clear more than 1.80m in the high jump at last year's home outdoor World Championships effectively kept her off the podium - she finished fifth in the individual high jump with 1.95m.

But there were no dramas here on a day when the high jump was her friend.

A clearance of 1.91m in the second event of the five won her the overall competition and lifted her into the lead.

A personal best of 12.68m in the shot put, her weakest event, was enough to keep her narrowly behind the leader, Cuba's Yorgelis Rodriguez, and she regained top place with a sound if not spectacular long jump of 6.50m at the start of the evening session.

This meant she had two seconds to spare over her rivals in the concluding 800m, which she won in 2min 16.63sec to total 4,750 points.   

Austria's Ivona Dadic took silver with 4,700, and bronze went to Cuba's Yorgelis Rodriguez, who scored a national indoor record of 4,637.

Marton's winning effort was the furthest thrown this season.

Danniel Thomas-Dodd of Jamaica took silver with a national indoor record of 19.22m, with bronze going to China's outdoor world champion Liiao Gong, whose best was 19.08m.

Earlier in the day there was a unique occurrence in the third heat of the men's 400m as all five runners were disqualified.

Qatar's Abdalleleh Haroun was first to go after false-starting. 

Grenada's Bralon Taplin, whose 44.88 run earlier this winter was the sixth fastest performance of all-time, appeared to have won comfortably in 46.37, which would have been the fastest time of the round.

But he and three men who followed him home - Jamaica's Steven Gale, Austris Karpinskis of Latvia and Alonzo Russell of The Bahamas - were all ruled out of contention for running out of their lanes before breaking from them - the first time this has happened in a Championship at this level.
