Peirsol is the world-record holder in the men's 100 and 200 backstroke and the proud owner of seven medals. He will face off against Lochte and Japan's Ryosuke Irie in the 100 and 200 backstroke in the Pan Pacifics. Irie swam the fastest 200 backstroke in history last year, but his time was not recognized because he used an unapproved suit. Whose hand will touch the wall first in these events is anyone's guess.
