LONDON -- Instead of one victory lap, Ashton Eaton got four.His Olympic gold medal in the decathlon was all but sealed when he reached the last event, the 1,500 meters, where he simply needed to finish in an average time to win the event on Thursday night.The world-record holder cruised over the four laps, crossed the line and -- even as exhausted as he was -- started celebrating.Eaton finished the two-day competition with 8,869 points to defeat fellow American Trey Hardee by 198. It's the first time the Americans have gone 1-2 in the Olympic decathlon since Milton Gray Campbell and Rafer Johnson in 1956."That's what Trey and I really, really wanted," said Eaton, who's from Eugene, Ore.Especially this year, on the 100th anniversary of the event. At the 1912 Olympics, Jim Thorpe won the inaugural title.Thanks to Eaton, the decathlon gold is staying in the United States. Eaton joins 2008 winner Bryan Clay and, of course, Bruce Jenner, in earning the honor as "The World's Greatest Athlete."Even Usain Bolt, the star of the night with his victory in the 200 meters, was impressed."I'm a great athlete, but to do 10 events, especially the 1,500 -- I've got to give it to him," Bolt said.Though the warm-and-sunny conditions in London were far better than the rain, wind and cold at U.S. Olympic trials in Oregon where Eaton broke the record earlier this summer, he fell short of the mark by 170 points.Not that it mattered. His goal was simply to win a medal, not eclipse his world mark of 9,039 points."I'm satisfied," Eaton said as he struggled to put his accomplishment into words.So Hardee did that for him.Given that Eaton is just 24 and heading into his prime, Hardee's not sure anyone is going to catch up to him anytime soon."It's safe to say my reign is over," said Hardee, a two-time world champion. "I still think my best decathlon is ahead of me, but Ashton's are, too."As the days and weeks and months and years pass, I think Ashton and I will look back on this and realize how special it really is and what this really meant."Eaton was consistent throughout the schedule. He started off by breaking Bill Toomey's 44-year-old Olympic record in the decathlon 100-meter dash and took off from there. He also scored the most points in the long jump and 400 meters.His only lackluster event was the discus, where he finished 22nd and lost points to the field. But it really didn't matter as he built his lead back up in the pole vault, where he wound up third.While Bolt won his fifth career gold on the track, the Americans were piling them up in other corners of the stadium.The U.S. also went 1-2 in the triple jump (Christian Taylor and Will Clay), raising the U.S. total to 24 medals, one more than what they won in Beijing, with three days to go."There was one world record established: David Rudisha of Kenya won the 800 meters in 1 minute, 40.91 seconds, improving his own standard by 0.10.Hoping to hone in on a little slice of the Bolt magic, Rudisha served up the prospect of a showdown over 400 meters against the Jamaican, who used to run that distance but abandoned it because it was too much of a grind.Bolt was more than happy to handicap that potential race."I think if I train, I can take Rudisha over 400 meters," he said.Former TCU sprinter Doc Patton will run in today's preliminaries of the men's 4x100 relay, joining Jeff Demps, Trell Kimmons and Ryan Bailey. Demps and Kimmons have no Olympic experience. The Americans likely are saving top sprinters Justin Gatlin and Tyson Gay for Saturday's final.Women's basketball: The U.S. faced its first Olympic halftime deficit in 12 years as it reach the gold medal game for the fifth straight time. The Americans used their defensive pressure to rally for an 86-73 win over Australia. Behind 6-foot-8 Liz Cambage, the Australians shot 61 percent and led 47-43 at halftime. The Americans will play France, which routed Russia 81-64, in Saturday's final.Women's volleyball: The Americans advanced to the final with a 25-20, 25-22, 25-22 victory over South Korea behind Destinee Hooker's 24 points.

The winner climbed out of the water, smiling and looking fresh. She even flexed for the big crowd.Risztov retired from swimming after the 2004 Olympics, upset with her results and tired of the pool.
