Phelps swam the lead-off leg of the 4x200m Relay. The U.S. team of Phelps, Lochte, Ricky Berens, and Vanderkaay demolished the world record with a time of 6:58.56, and leaving runners-up Russia more than 5 seconds behind.
Another world record for Phelps as he swam a 1:54.23.
In the closest and most controversial of Phelps’ races, Phelps edged out Serbian Milorad Cavic. Cavic had a commanding lead after 50 meters, when Phelps started to chase him down. Phelps ended up out touching him by the slimmest of margins, 0.01 seconds. His 50.58 second swim set an Olympic record.
