Ye started the final leg of the race well behind American Elizabeth Beisel. By the 50m turn of the freestyle, Ye had taken the lead and, by the end, had streeted her like a greyhound bounding after a fox terrier. When Beisel took off her goggles, she looked like a fighter waking up from a slumber after being caught with a sucker-punch. Where the hell did that come from? Ye Shiwen ... making waves.

The immense improvement in times, the supreme power and the complete domination of an elite field could lead to only one conclusion - the Chinese were up to their old tricks. The fact a former squadmate in China, Li Zhesi, tested positive for EPO in March didn't aid Ye's cause. John Leonard, the executive director of the World Swimming Coaches Association, bought into the argument. He told London’s The Guardian her performance in the final was "suspicious". "We want to be very careful about calling it doping," said Leonard, who is also the executive director of the USA Swimming Coaches Association.

"The one thing I will say is that history in our sport will tell you that every time we see something, and I will put quotation marks around this, 'unbelievable', history shows us that it turns out later on there was doping involved. That last 100m was reminiscent of some old East German swimmers, for people who have been around a while. It was reminiscent of the 400m individual medley by a young Irish woman [Michelle de Bruin] in Atlanta." Shiwen Ye ... selected for the size of her hands. We're all best served by a step back at this point. Tarring Ye with the doping brush by association isn't even close to fair. If this was an Australian athlete, we'd be mortified by the mere suggestion and celebrating the athletic vigour of our bronzed youth. It wasn't an insinuation Rice had to deal with when she clocked her world record in 2008, which was at the time an absurdly fast result. Earlier that year, Rice shaved a startling six seconds off her personal best time to hit 4.31.46 at the Australian trials. American Katie Hoff reclaimed the mark a few months late before Rice countered at the Beijing Games, reducing it to below 4.30 for the first time. In contrast, people seized on the fact Ye reduced her PB by five seconds to claim the new mark of 4.28.43 as genuine grounds for suspicion.

The sexiest line has been Ye's apples-to-apples comparison with American men's star Ryan Lochte, who humbled Michael Phelps in his gold-medal 400 IM swim on the first night of competition. The Chinese teen clocked 28.93 for her final 50m freestyle leg, compared to Lochte's 29.10. Leonard told The Guardian: "No coach that I spoke to could ever recall seeing anything remotely like that in a world level competition. Where someone could out-split one of the fastest male swimmers in the world, and beat the woman ahead of her by three-and-a-half body lengths. All those things, I think, legitimately call that swim into question." Her teacher noticed she had hands like buckets and she was soon using them to paddle up and down the pool It was a barnstormer of a swim. 'Faster than Lochte' headlines flashed around the world and, suddenly, a 16-year-old girl was quicker than a full-grown US superman. It's juicy and accurate, to a point. But surgically removing one stat from a 400m swimming race and seizing upon it has warped perceptions and conclusion. That freestyle leg was dazzling but Ye isn't faster than Lochte. Not even close. Lochte's winning time in the men's 400m IM was 4.05.18, compared to Ye's 4.28.43. That's a difference of 23.25 seconds. And Lochte's lead-off relay sprint for the US men's team was 47.89, a number to which Ye couldn't get close despite being a gun freestyler.

The manner in which the races were swum adds another layer. Lochte had the race in hand by the time he turned on the freestyle leg. His other three strokes were good enough to give him a gold-medal lead and there was no clear and present danger ranging up on either side. Ye had to hit the burners to motor past Beisel. She turned more than a body length behind and had to push with everything she had to catch the American. By the time she did that, it must have been clear a world record was within reach and she drove it home with Black Caviar authority. In any case, four other male swimmers did beat Ye's freestyle split. To the wider sporting world, Ye is only now becoming a notable name. Yet to swimming diehards, she has been one of the rising stars for some years, even if her surge of form in London has caught most people by surprise. Beisel and Rice had been the favourites for gold. Ye won the 200m IM at the Asian Games in 2010 (2.09.37) and the 400m IM (4.33.79), all at age 14. At the time, she was listed at 160cm tall. Now, the official Olympic site lists her 12 cm loftier at 172cm. That sort of difference in height, length of stroke and size of hand leads to warp-speed improvement. Ye was picked for the Chinese swimming program because of her hands. Her finger-painting brush strokes at kindergarten must have been an inch wide. Whatever it was, her teacher noticed she had hands like buckets and she was soon using them to paddle up and down the pool.
