YOKOHAMA -- Before taking the team bus to Yokohama pool, American Michael Phelps went online in his hotel room and checked out a world record. Not Ian Thorpe's, but the men's 4x100 medley relay.
It certainly paid dividends.
In the grand finale race of the Pan Pacific Swimming Championships, the United States men's relay team shattered the world record by .25 of a second in 3 minutes, 33.48 seconds. The first world record broken in the six-day meet capped another day of U.S. domination.
