A

Michael Phelps and his U.S. teammates crowned the greatest single Olympic performance Sunday morning with a win in the 4×100-meter medley relay(混合泳接力).

The victory gave Phelps his eighth gold medal of the Beijing Olympics, the most golds ever won by an athlete at one Games. With gold No. 8, Phelps earned an unusual place in the Olympic record books.

"There is no comparison in the swimming world for what Michael has done," said Gregg Troy, coach of U.S. swimmer Ryan Lochte, who finished third to Phelps in two races here in Beijing but also won gold alongside him in the 4×200-meter freestyle relay. It's hard to find comparisons even in the sports world overall. Phelps is solidly in the company of seemingly undefeatable superstars such as Michael Jordan and Tiger Woods.

"I think years and years down the road we'll realize more and more how amazing he is and how special he really is." U. S. teammate Natalie Coughlin said. The 23-year-old from Baltimore capped a brilliant meet at the Water Cube. He set a world record in every event aside from the 100 butterfly which he narrowly won on Saturday, completing a program of 17 races in nine days.

Phelps has won 14 Olympic gold medals and 16 total medals. He holds the record for most medals won by a man, surpassing Soviet gymnast Nikolai Andrianov, who won 15 from 1972-1980. Soviet female gymnast Larysa Latynina holds the record with 18.

At the 2004 Athens Games, Phelps won six gold medals and two bronze. He has already said he'll swim in the 2012 London Games. Phelps' victories in Beijing include: 200-meter freestyle, 200 and 400 individual medleys, 100 and 200 butterfly, 4×200 free relay, 4×100 medley relay, and 4×100 free relay.
