Michael Phelps' storied Olympic career came to a close in the most fitting fashion possible. Phelps and the United States earned another gold medal in the 400m individual relay -- an event the United States has never lost.
Phelps was joined on the team by Matt Grevers, Brendan Hansen and Nathan Adrian. The quartet of American swimmers finished the race with a time of 3:29.25 -- nearly two seconds better than the Japanese, who earned the silver medal with a time of 3:31.26. Australia finished in third, earning bronze with a time of 3:31.58.
For Phelps, the gold medal represents the 18th gold of his legendary Olympic career. Phelps also has four silver medals to his credit, giving him a staggering 22 career medals. Phelps earned six of those medals at the 2012 Olympic Games, where he has taken home four gold and two silver.
It's truly the only way Phelps' career could end.
