Lochte touched in a time of one minute 54.98 seconds, almost a second slower than the world record of 1:54.00 he set to win the gold in 2011. Kosuke Hagino of Japan was second in 1:56.29 and Thiago Pereira of Brazil third in 1:56.30.
Lochte is the second man only after compatriot Michael Phelps to win a treble of 200
Phelps took gold in the event in 2003, 2005 and 2007 and beat Lochte into second place to win the Olympic title in London last year.
