It's 8: Phelps passes Spitz with another gold

Jason Lezak held on to the lead Phelps gave him, anchoring the United States to a world record in the 400-meter medley relay against an Australian team that did its best to spoil history.

But Phelps, with a big hand from three teammates, would not be denied. He eclipsed Mark Spitz's seven-gold performance at the 1972 Munich Games, an iconic performance that was surpassed by a swimmer fitting of this generation: a 23-year-old from Baltimore who loves hip-hop music and texting with his buddies.

Even though the Americans have never lost the medley relay at the Olympics, the latest gold was hardly a breeze. When Phelps dove into the water for the butterfly — the third of four legs — the Americans were third behind Japan and Australia.

But Phelps, swimming the same distance and stroke that he used to win his seventh gold a day earlier, powered back to the front on his return lap, passing off to Lezak with the Americans in front.
