BEIJING (AP) -- Michael Phelps locked arms with his three teammates, as though they were in a football huddle calling a play, then hugged each one of them. It took a team to make him the grandest of Olympic champions. And one last big push from Phelps himself.
Going hard right to the end of a mesmerizing nine days in Beijing, Phelps helped the Americans come from behind Sunday in a race they've never lost at the Olympics, cheering from the deck as Jason Lezak brought it home for a world record in the 400-meter medley relay. It was Phelps' history-making eighth gold medal of these games.
"Everything was accomplished," he said. "I will have the medals forever."
Phelps sure did his part to win No. 8, eclipsing Mark Spitz's seven-gold performance at the 1972 Munich Games.
Aaron Peirsol got the Americans off to the lead in the backstroke, but Brendan Hansen - a major disappointment in this Olympic year - slowed them down with only the third-fastest breaststroke leg.
By the time Phelps dived in for the butterfly, the U.S. was trailing Australia and Japan.
That's when he really went to work.
With his long arms whirling across the water like propellers, Phelps caught the two guys ahead of him on the return lap and passed off to Lezak a lead of less than a second for the freestyle. The Australians countered with former world record-holder Eamon Sullivan as their anchor.
"I was thinking not to blow the lead," Lezak said. "I was really nervous."
Sullivan tried to chase down Lezak and appeared to be gaining as they came to the wall, but Lezak finished in 3 minutes, 29.34 seconds - Phelps' seventh world record in his personal Great Haul of China.
The Aussies took silver in 3:30.04, also under the old world record of 3:30.68 set by the U.S. in Athens four years ago, while Japan held on for the bronze.
Phelps leaned over the blocks, looking to make sure Lezak touched first. Assured the Americans had won, he thrust both index fingers in the air, pumped his right arm and let out a scream. Peirsol also yelled and slapped Phelps in the chest.
Spitz's iconic performance was surpassed by a swimmer fitting of this generation: a 23-year-old from Baltimore who loves hip-hop music, texting with his buddies and wearing his cap backward.
"I don't even know what to feel right now," Phelps said. "There's so much emotion going through my head and so much excitement. I kind of just want to see my mom."
Debbie Phelps was sitting in the stands at the Water Cube, tears streaming down her cheeks, her two daughters by her side. After getting his gold, Phelps quickly found his family, climbing through a horde of photographers to give all three a kiss.
Mom put her arm around his neck and gave him a little extra hug.
Her son sure earned it.
"The Beijing Olympics has witnessed the greatest Olympian of all time - Michael Phelps of the USA," the announcer said as Phelps posed with his teammates.
The Americans still had to wait a couple of tantalizing minutes for the official results to be posted. Finally, it flashed on the board.
Gold medal No. 8.
"Nothing is impossible," Phelps said. "With so many people saying it couldn't be done, all it takes is an imagination, and that's something I learned and something that helped me."
Phelps, who won three relays in Beijing along with five individual races, gave a shout-out to all his teammates for helping him take down Spitz.
"Without the help of my teammates this isn't possible," he said. "I was able to be a part of three relays and we were able to put up a solid team effort and we came together as one unit.
"For the three Olympics I've been a part of, this is by far the closest men's team that we've ever had. I didn't know everybody coming into this Olympics, but I feel going out I know every single person very well. The team that we had is the difference."
Phelps set seven world records and one Olympic record, doing a personal best time in every event.
"It can't be described. We'll never, ever see it again," said Australian distance king Grant Hackett, who came up short in his bid to win a third straight 1,500 freestyle title.
Beforehand, Hackett figured Phelps was likely to win six golds, just as he did in Athens four years ago when the first attempt to beat Spitz's record came up just short.
"Everything lined up for him incredibly," Hackett said. "He's a nice guy, a good bloke, and the last few years I've never seen him change."
