“I am really proud of my race," he said.

"I have not swum in two years competitively, but I knew I had a lot in me.

"It is great to be here in Berlin."

Great Britain’s Jonathan Fox, finished second with 940 and a time of 2:32.68 which was a world record in the S7 class.

The Netherlands' Olivier van de Voort posted a time of 2:06.41 to earn 928 and set a S10 world record while Griswold’s compatriot Jordan Catchpole completed the sensational set of results by setting a S14 record of 2:18.31, which saw him collect 767.
