After the United States claimed emphatic victories in both the men's and women's 4x400 metre relays, Duplantis took centre stage and duly delivered a perfect finale for the first championships on American soil.
The Swede sailed over 6.21 metres to surpass his previous mark by one centimetre - set in March en route to winning gold at the World Indoor Championships - and complete his collection of medals by claiming a first world title.
