LONDON — American Tyler Clary passed defending champion Ryan Lochte on the last lap and set an Olympic record to win the 200-meter backstroke at the London Games on Thursday.
Clary clocked 1 minute, 53.41 seconds to improve on the previous mark of 1:53.94 set by Lochte at the 2008 Beijing Games in a now-banned bodysuit.
‘‘You always have big dreams in your head that you think you might be able to pull off something like that,’’ Clary said.
‘‘The fact that it just came to fruition is something that hasn’t even processed in my mind yet. The fact that I’m now an Olympic champion and Olympic-record holder is something that is very humbling. It’s also very motivating for the next four years.’
Ryosuke Irie of Japan touched in 1:53.78 to take the silver medal and Lochte finished in 1:53.94 for bronze.
