AUSTIN, Texas (AP) -- Michael Phelps erased the pool record that was also his first world record with a finish of one minute, 54.79 seconds in Sunday's 200-meter butterfly final. At the Austin Elite swimming competition, the 14-time Olympic gold medallist led the entire way, touching the wall ahead of China's Wu Peng, who finished in 1:56.71, and Neil Caskey in 1:59.82. "I wanted my record to stand," Phelps said afterwards. "I wanted the pool record to stand just because that was my first world record." Phelps set the old record of 1:54.92 as a 15-year-old in 2001 qualifying for that year's FINA World Aquatics Championship. He would break his own world record and become world champion for the first time later that summer at the competition in Japan.
