McGrath retained his men's KL2 200 metres title at the Hungarian venue in impressive style.

The Paralympic champion finished in a time of 42.35sec to clinch a fourth world title, confirming his status as favourite for Tokyo 2020.

Italy's Federico Mancarella came second in 42.80, with New Zealand's Scott Martlew completing the podium in 43.51.

"This is probably the most nervous I have ever been, I think because the field is getting closer and the competition is heating up," McGrath said.

"I need to work on my mental side of things, focusing on and zeroing in on what I can do.

"A win is a win, but there are always things to improve on."

Chile's Katherine Wollermann earned bronze in 58.03.
