The 27-year-old American cleared a world leading mark of 4.86 metres with the Greek vaulter only able to register 4.71m at the New Balance Indoor Grand Prix event.

It means a new rival has emerged for Stefanidi, the Rio 2016 Olympic champion and London 2017 world gold medallist.

"This felt really good," said Nageotte after her win at the Reggie Lewis Track and Athletic Center.

"It felt like I was really putting together the things we've been working on. 

"It's a great place to jump."

With the event in January, several world leading marks were set.

Ethiopia's world indoor champion Yomif Kejelcha set a national indoor record of 3min 51.70sec to win the men's mile as Gabriela DeBues-Stafford of Canada won the women's equivalent in 4:24.80.

The men's 800m was clinched by home runner Donavan Brazier in 1:45.91 as the women's crown over 600m went to Raevyn Rogers of the US in 1:27.31.

In the women's 60m Michelle-Lee Ahye of Trinidad and Tobago recorded 7.21 for victory while the men's 3,000m title went to Ethiopia's Hagos Gebrhiwet in 7:37.41.

The women's 500m saw victory for American Sydney McLaughlin in her first professional race.

Last year's IAAF Female Rising Star award winner clocked 1:09.46.

Field events saw an impressive shot put mark of 19.28m which sealed victory for American Maggie Ewen.

The Indoor Tour will continue on February 2 in Karlsruhe in Germany.
