Olympic organizers and swimming's governing body angrily leapt to the defense of China's world record-breaking teen sensation Ye Shiwen on Tuesday, with the sport's president saying suspicions that she doped were "crazy" and motivated by jealousy and the IOC stressing its confidence in the drug-testing program.

"We need to get real here," said International Olympic Committee spokesman Mark Adams. "These are the world's best athletes competing at the very highest level. We've seen all sorts of records broken already all over the place."

Adams said the top five athletes in each event, plus two others, are tested as part of "a very, very strong drug-testing program, and we are very confident if there are cheats we will catch them."

"We can't stop speculation. It is inevitably a sad result of the fact that there are people who dope and who cheat," Adams said. "It's very sad we can't applaud a great performance. Let's give the benefit of the doubt to the athletes."

Ye won the 400-meter individual medley on the opening day of the Olympic swimming competition, and was the favorite to win the 200 IM on Tuesday evening, too.

The 16-year-old Ye sliced through the last lap of the 400 in 28.93 seconds - faster than the 29.10 American winner Ryan Lochte posted in the last 50 of the men's race. Ye's time was 4:28.43, more than a second faster than the previous world record set by Australia's Stephanie Rice at the 2008 Beijing Games in a now-banned bodysuit.

US Media has been spurning stories on foreign athletes particularly Chinese and to a lesser extent Russian every time they and not American athletes break world records. If a Chinese breaks WR and win gold, the US media and Coaches publicly state their suspicion they must be doped up, otherwise an American would win.

Ironically, it's American athletes who have lengthy history of doping: Justin Gatlin, Marion Jones, Karl Lewis, Lance Armstrong ....
