The Guernsey 400m hurdles star finished strongly to come through his heat in fourth place in a time of 48.86.
That puts him 23rd out of the 24 athletes to progress, but is over half a second short of the 48.30 personal best he set earlier this season and which would have been enough for eighth across today’s five heats.
The Commonwealth Games medallist and multiple national champion is competing at his second world championships and has been targeting a place in the final, having also reached the semis in Eugene in the United States in 2022.
He will be back on the track to see if he can fulfill that ambition on Wednesday afternoon UK time, when he will line up in the third of three semi-final heats at 13:46 BST.
The first two in each will go through along with the next fastest two overall.
