Olympian Katie Ledecky broke the world record in the 400-meter freestyle for the second time in two weeks at the Pan Pacific championships in Gold Coast, Australia.
The 17-year-old won in 3 minutes, 58.37 seconds on Saturday night, shaving .49 seconds from the mark she set Aug. 9 at the U.S. Championships.
It was her fourth gold medal of the Pan Pac meet, and the Stanford commit is a lock in the 1,500 free if she swims it as scheduled Sunday.
It was Ledecky's fourth world-record swim of 2014, the first two in the 800 and 1,500 freestyle events in June.
"It's a great feeling," she said. "It never really gets old."
Michael Phelps claimed the first significant win of his comeback by taking the men's 100 butterfly in 51.29 seconds. He edged Ryan Lochte (51.67).
Phelps, Lochte and former Cal stars Nathan Adrian and Anthony Ervin placed second in the men's 400 free relay, and the Bears' Missy Franklin was part of the U.S.'s silver-medal winning team in the women's 400 free relay.
Julie Johnston, a former All-American at Santa Clara, is the National Women's Soccer League Rookie of the Year. She had two goals and two assists in 21 games with the Chicago Red Stars.

Stanford coach Mark Marquess announced the addition of three assistant coaches -- Brock Ungricht, Jon Karcich and Eric Smith.
