South Korea's Park Tae-kwan rallied to win the 400-metre freestyle over Victoria's Ryan Cochrane at the Pan Pacific championships on Friday night in Irvine, Calif.
Park won in three minutes 44.73 seconds, the world's fastest time this year. The Olympic champion was neck-and-neck with Cochrane through 300 metres before pulling away on the final two laps.
Cochrane earned the silver medal in 3:46.78. China's Zhang Lin, the Olympic silver medallist who had the world's fastest time coming in, took bronze in 3:46.91.
Later Friday, Canada added two more bronze medals.
Vancouver's Scott Dickens was third in the men's 50-metre breaststroke, finishing in a time of 27.63, just behind winner Felipe Silva of Brazil (27.26) and American Mark Gangloff (27.52).
Canada also won bronze in the women's 400-metre freestyle relay.
Victoria Poon and Genevieve Saumur, both of Montreal, Victoria's Julia Wilkinson and Calgary's Erica Morningstar finished in 3:38.14. The United States was first in 3:35.11, while Australia took second in 3:38.06.
In the men's 400-metre freestyle relays, Michael Phelps earned his fourth medal of the meet while Ryan Lochte claimed his fifth as the U.S. won gold in 3:11.74.
Australia finished second in 3:14.30, while South Africa (3:15.93) was third.
Phelps rockets out to lead
Phelps led off the relay with a meet-record 100 split of 48.13 against Canada's Brent Hayden, whose mark of 48.59 Phelps lowered from four years ago.
The Canadian team of Vancouver's Hayden, Edmonton's Luke Peddie, Colin Russell of Oakville, Ont., and Richard Hortness of Medicine Hat, Alta., were fourth in 3:16.53.
Phelps led all the way in winning the 100-metre butterfly.
The world and American Olympic champion touched in 50.86 seconds, erasing countryman Ian Crocker's meet record of 51.47 set four years ago. Phelps posted the year's fastest time of 50.65 in winning the title at U.S. nationals earlier this month.
Phelps' teammate Tyler McGill earned the silver in 51.85. Takuro Fujii of Japan took the bronze.
Phelps rested on the lane rope and watched the race replay on the giant video board above the outdoor pool.
"I guess I was off the blocks slow. The one thing I'm not happy with was the first 50. I couldn't get it going," he said. "To be able to still be under 51 wasn't terrible. If I want to be able to get back to the time I did last summer [at worlds], I just need a good first 50 to build up my speed."
Lochte wins 200m backstroke
Lochte won the 200-metre backstroke in 1:54.12 seconds, the world's fastest time this year. That eclipsed the meet record of 1:54.44 set by Aaron Peirsol four years ago.
"I felt pretty in control. I tried to hold back on my first 50," said Lochte, who hit the lane rope near the end. "I was trying to stay in the middle but it didn't work."
American Tyler Clary earned the silver in 1:54.90. Ryosuke Irie of Japan, the world silver medallist who came in with the world's best time, was third.
Montreal's Charles Francis finished seventh in 2:00.37, while Toronto's Tobias Oriwol as eighth in 2:00.79.
Jessica Hardy won the women's 50-metre breaststroke, a non-Olympic event, in 30.03 for the third-fastest time ever.
Chelsey Salli of Langley, B.C., was sixth in 31.55, while Ashley McGregor of Pointe Claire, Que., finished eighth in 32.01.
U.S. teammates Dana Vollmer and Christine Magnuson went 1-2 in the 100 butterfly. Vollmer was timed in 57.56 and earned her first gold and third medal of the meet.
Magnuson, the Olympic silver medallist who owns the world's fastest time this year, was second in 57.95. Yolane Kukla, a 14-year-old Australian, was on world-record pace after 50 metres, but faded to fourth.
Katerine Savard of Pont-Rouge, Que., was sixth in 58.92 and Audrey Lacroix, also of Pont-Rouge, was seventh in 59.22.
U.S. domination in backstroke
The United States also dominated the women's 200 backstroke, with 18-year-old Olympian Elizabeth Beisel holding off 16-year-old teammate Elizabeth Pelton at the wall to win. Beisel finished in 2:07.83 to Pelton's 2:08.10. Australia's Belinda Hocking took the bronze.
Genevieve Cantin of Saguenay, Que., was sixth in 2:11.56, while Vancouver's Lauren Lavigna was seventh in 2:11.89.
Sutton touched in 4:05.19, the fourth-fastest time in the world this year.
Goldman was second in 4:05.84 and Evans third in 4:06.36. American Allison Schmitt, cheered on by former training partner Phelps, was fourth.
Montreal's Barbara Jardin was sixth in 4:11.53, while Victoria's Alexa Komarnycky was seventh 4:12.67.
Sutton, a 2008 Olympian, earned a silver medal in the 800 free on Wednesday. She will swim in the 10-kilometre open water race on Sunday.
American Kate Ziegler won the consolation final in 4:05.22, which would have been good for the silver but only two swimmers per country are allowed in the championship final.
