A British clean sweep in the men's S8 400 metres freestyle at the Aquatics Centre appears a distinct possibility after brothers Sam and Oliver Hynd and ParalympicsGB team-mate Thomas Young filled the top three places in qualifying for tonight's final.
The trio claimed a one-two-three at last year's European Championships in Berlin, Sam Hynd leading the way ahead of younger brother Oliver with Young taking bronze.
Sam Hynd was fastest through this morning in four minutes 33.25 seconds, Young and Oliver Hynd filling second and third.
For the elder Hynd, his effort was what he had planned for and he said: "A very good swim, I was really pleased with how it went.
"The tactics were right on what me and my coach set.
"I'm glad to get the heat out of the way. All the pressure's off after that."
Brother Oliver was less pleased however with his time of 4mins 36.40secs, saying: "It's a heat swim, you get a lane in the final and that is all it is after in the morning.
"I would have liked to have been a little bit faster but I've got another opportunity to swim faster tonight."
Of whether he would spend time with his brother before the final, he said: "We don't really talk about it: we just go about our normal business and then meet each other in the pool."
Young, though, was more satisfied with his 4:34.16 effort and believes they can repeat their clean sweep from Berlin.
He said: "It was quicker than I thought it would be, I think the crowd picked me up on that last 150.
"I just wanted to go in and see what I've got and it shows I've got a lot left in the tank for that final tonight so it could be a 1-2-3 I reckon."
