BEIJING — For Michael Phelps, it's not enough to just set a new standard. He has to demolish the old one.

Winningest Olympian ever? He's two golds past that already and not finished yet, just over halfway to his goal of breaking Mark Spitz's record seven in a single Olympics.

World records? In a sport measured down to the hundredths for a reason, Phelps sets a pace to crush one of them by more than four seconds.

Even when his goggles malfunctioned during the first race today in China, the gangly, 23-year-old American squinted through water-filled lenses on the way to, yes, a world record. Of course, he was none too happy to beat it by only six-hundredths.

So un-Phelps-like.

"In the circumstances, not too bad I guess," he said with a shrug. "I know I can go faster."

No wonder his competitors realize they're merely swimming for second.

Monumental challenges for mere mortals seem almost inconsequential to Phelps.

"He is just a normal person, but maybe from a different planet," said Russia's Alexander Sukhorukov, fresh off a thrashing by the Phelps-led Americans but still good enough to have a silver around his neck.

Today, Phelps swam into history as the winningest Olympic athlete in history with his 10th and 11th career gold medals — and five world records in five events at the Beijing Games.

A day after etching his name alongside Mark Spitz and Carl Lewis with gold No. 9, Phelps set a standard all his own when he won the 200-meter butterfly. An hour later, he swam the leadoff of a runaway victory by the U.S. 800 freestyle relay team, which shattered the old world mark in becoming the first team to break the 7-minute barrier.

Seemingly impervious to fatigue, he set a blistering pace of 1 minute, 43.31 seconds that got the Americans rolling toward a winning time of 6:58.56.

"Come on! Come on!" he screamed at teammates Ryan Lochte, Ricky Berens and Peter Vanderkaay.

The previous record of 7:03.24 was set by the Americans at last year's world championships. Russia took the silver, more than five seconds behind the Americans, who mainly had to make sure they didn't get in the water too soon. Australia won the bronze.

After a six-gold performance at the 2004 Athens Games, Phelps needed only five days in Beijing to surpass Spitz, Lewis, Soviet gymnast Larysa Latynina and Finnish runner Paavo Nurmi as the winningest Olympian in history.

"I'm almost at a loss for words," Phelps said. "Growing up I always wanted to be an Olympian. Now to be the most decorated Olympian of all time, it just sounds weird saying."

Phelps has three more chances to stretch his lead before he leaves China. He'll swim in the 200 individual medley, 100 fly and 400 medley relay.

"There is still something left in the tank," Phelps said.

In his signature stroke, the butterfly, Phelps was second at the first flip, then pushed it into another gear, his long arms gobbling up huge chunks of water as he literally sailed along atop the surface. He finished in 1:52.03, breaking his mark of 1:52.09 from the 2007 worlds.

Phelps barely smiled as he looked at the board, breathing heavily and hanging on the lane rope. Hungary's Laszlo Cseh really pushed it at the end, but settled for silver in 1:52.70. Japan's Takeshi Matsuda took the bronze in 1:52.97.

Phelps rubbed his eyes and said climbing from the pool, "I can't see anything." A pair of leaky goggles kept him from seeing the wall as he touched.

"My goggles kept filling up with water during the race," Phelps said. "I wanted 1:51 or better."

Still, he had two more golds and two more records, leaving him just three wins away from beating Spitz's record in the 1972 Munich Games.

"There is nobody in our sport that can win like he wins," U.S. head coach Eddie Reese said.

In the women's 200 free, Italy's Federica Pellegrini broke the mark she set a day earlier in the semifinals, winning gold in 1:54.82.

Sara Isakovic of Slovenia claimed the bronze in 1:54.97, and China's Pang Jiaying passed Katie Hoff on the final lap to take bronze in 1:55.05.

In the 200 individual medley, Australia's Stephanie Rice completed her IM sweep with another world record, her time of 2:08.45 erasing the mark of 2:08.92 set at the Australian trials in March.

Kirsty Coventry of Zimbabwe took the silver in 2:08.59. Natalie Coughlin of the U.S. won the bronze in 2:10.34.
