After helping his team cruise to a gold medal victory in the men's 4x200 freestyle relay, Michael Phelps officially became the most decorate Olympic athlete of all-time on Tuesday night in London.
Phelps took a disappointing second in the 200m butterfly earlier in the evening to tie the Olympic career medal record of 18, after what proved to be an all-too-narrow loss to South African gold medalist Chad Ie Clos by 0.05 seconds on the clock. Phelps and his American team wasted little time asserting their dominance on the 4x200 relay less than an hour later however, as they hit the wall more than three seconds before any of their competitors to clock a time of 6:59.70. Team USA's winning time was just a second slower than their 2008 world record time of 6:58.55 in Beijing, but it's clear the Americans are tops when it comes to men's relay events.
Still with three events remaining, Phelps will have plenty of chances to add to his seemingly insurmountable career tally before the Olympics wraps up.
