- Australia's Cameron McEvoy upset a star-studded field to win the 100m freestyle at the Pan Pacific Championships as Michael Phelps claimed his first international gold medal since coming out of retirement.

McEvoy swam the race of his life to hit the wall in the third-best time this year of 47.82 seconds ahead of US Olympic champion Nathan Adrian (48.30) and dual world champion James Magnussen (48.36).

Phelps led to the turn before finishing fourth in 48.51sec, which clinched his place on the US team for the event at next year's world championships.

But the American also claimed a gold medal as part of the United States' 4x200m freestyle relay, adding to his haul of international titles just four months into his comeback.

"I was able to swim it exactly much the same as I swam this morning," Phelps said of the individual race. "I was out slow, back faster, my finish was really bad, but overall I know what I have to do to get better."
