Six weeks ago, a 16-year-old former team-mate of Ye's, Li Zhesi, tested positive for erythropoeitin (EPO), the blood-booster. The case was announced by the China Anti-Doping Agency (Chinada), which cited "an out-of-competition test carried out on March 31". No suspension has yet been announced nor was FINA, the international federation, aware of the case when asked about it yesterday.
But for the ban, Li would most surely have been here. She turned 13 the day before her home Games got under way in Beijing in 2008. A year later, at 14, she became a world champion as a member of the China women's 4x100 metres medley quartet.
Put Li together with Ye's freakish performance against the backdrop of a doping-soaked 1990s, during which Chinese swimmers produced more than 40 positive steroid tests, and it is clear why questions are being asked.
