The United States' Justin Zook has edged a very close S10 100m backstroke final and has broken the world record in the process.
There was almost nothing between the top two and it could have been Zook or Andre Brasil of Brazil who took gold.
In the end it was Zook who touched the wall just 0.1s before Brasil, his world record time setting at 1:00.01.
Bronze went to Benoit Huot of Canada, who was comfortably third with 1:00.73.
