Michael Phelps brought the curtain down on one of sport's most storied careers with a dynamite relay swim to give himself 23 Olympic gold medals and declared it a perfect finale. The American, far and away the most decorated athlete in Olympic history, finished with five golds and a silver in Rio after signing off in dramatic style, coming to the rescue in the 4x100m medley final. Turning back the clock in his fifth and final Games, Phelps produced a blistering third leg of butterfly to restore his team's lead and tee up victory after Britain's Adam Peaty had threatened to gatecrash his party. "Getting off the bus and walking to the pool tonight, I pretty much felt myself starting to crack," confessed Phelps. "Last warm-up, last time putting on a suit, last time walking out in front of people, representing my country — it's insane, a lot better than it was four years ago," added the 31-year-old, who retired after the 2012 London Games before returning for one last hurrah. "This is how I wanted to finish my career. I've lived a dream come true. Being able to cap it off with these Games is just the perfect way to finish." The hullabaloo over the Phelps's farewell overshadowed the achievement of the women's 4x100m medley relayers as they captured their country's 1,000th Olympic medal, according to the United States Olympic committee. The country's first medal dates back to 1896, when James Connolly won triple jump gold. Even that statistic seemed to pale against the irrepressible Phelps — and likewise Ryan Murphy's leadoff backstroke leg, which set a new 100m world record of 51.85. Nathan Adrian brought the Americans home to preserve its unbeaten Olympic record in the event and give them a 16th swimming gold from 32 events for the week, matching their haul in London four years ago. An Olympic record time of 3:27.95 was lost in the emotion after the race as Phelps tearfully saluted the crowd while his beauty queen fiancee Nicole Johnson looked on sobbing as she cradled baby son Boomer. Britain took silver, thanks largely to a breaststroke leg from Peaty that was quicker than the world record he set to win individual gold, but won't count as it came in the middle of a relay. Australia claimed bronze, but the memory of sharing the pool with Phelps in his final race could last longer than the glow of their relay gongs. The women's quartet of Kathleen Baker, Lilly King, Simone Manuel and Dana Vollmer made history, but were made to work. The Americans, who failed to medal at last year's world championships, had looked in peril when two-time doping violator Yulia Efimova gave Russia the lead on the breaststroke. But Vollmer's butterfly averted a crisis and Manuel brought them home in 3:53.13 almost two seconds ahead of Australia with Denmark taking bronze. Pernille Blume, who swam Denmark's anchor leg, earlier won gold in the women's 50m free, inflicting more heartbreak on Australia's Cate Campbell after her 100m flop. Blume won in 24.07 with Manuel adding silver to her surprise 100m gold with a time of 24.09 and Aliaksandra Herasimenia of Belarus, the London runner-up previously banned for doping, taking bronze. Campbell returned around 20 minutes later for the 4x100 medley relay but despite a fine anchor leg could not prevent the United States retaining their Olympic title. World champion Gregorio Paltrinieri blazed to gold in the men's 1,500m in the absence of defending champion Sun Yang, who crushed out in the heats blaming a cold, the Italian smashing a quality field to win in 14:34.57. Connor Jaeger of the US took the silver, and Italy's Gabriele Detti won bronze after overhauling Jordan Wilimovsky of the US in the closing stages.
