The United States capped a dominant performance at the Pan Pacific Swimming Championships with five gold medals and a world record in the men’s 4×100-meter medley relay Thursday.
Aaron Peirsol, Brendan Hansen, Michael Phelps and Jason Lezak clocked 3 minutes 33.48 seconds, eclipsing the previous world mark of 3:33.73 set by the U.S. at the 2000 Olympics.
“Going into the race we all wanted that record,” said Phelps, who swam the butterfly leg after winning the 200 individual medley earlier Thursday. The relay victory gave the U.S. 21 gold medals. Australia was next with 11.
Ian Crocker (100 butterfly), Natalie Coughlin (women’s 100 freestyle) and Margaret Hoelzer (200 backstroke) also won gold.
Ian Thorpe anchored the Australian team to second place in the 4×100, adding a silver to his five gold medals at the meet.
