Keshorn Walcott has thanked his coach Dr Klaus Bartonietz, a German biomechanics expert, for the world championships title on Thursday.
Bartonietz is the same man who guided Neeraj Chopra's career through Olympic and world championships glory over the past half a decade.
Having parted ways with Chopra Bartonietz linked up with Walcott and the results have been instantaneous. The Trinidad and Tobago native threw a season-best 88.16m to top the field and claim a worlds gold. It's a success that comes 13 years after he won the Olympic gold medal in London.
"It's been a long 13 years. 2016 has been my last time on the (major international) podium. The World Championships medal has always been out of my reach but thankfully tonight I've gotten it."
He said he could not have done it without Bartonietz,
"I wanna thank my coach for actually trusting me this year and giving me the chance to be able to be coached by him. We made some good changes, and you see it paid off tonight. That was one of my biggest blessings for 2025."
