TEAHUPO'O, Tahiti -- Brazil's Gabriel Medina powered through a giant blue barrel for the highest score of the Olympic surfing competition so far, but Tahiti's Teahupo'o stole the show on Monday with some of the most incredible waves on Earth.

The decision to hold the surfing competition at the perfect reef pass of Teahupo'o proved inspired as the swell rose and a forecasted storm held off just long enough to complete the men's third round.

After two days of competition in waves that were mostly user-friendly, Teahupo'o, which loosely translates as "Wall of Skulls" after a gruesome local legend, really bared its teeth as a solid southwest swell rose overnight.

Time after time, surfers paddled hard and threw themselves into the waves, which sucked below sea-level as they hit the reef.

Those that got it right were spat out of the fearsome tubes, shrouded in firehose blasts of spray. Horrendous wipeouts, broken boards and Jet Ski rescues followed for those that didn't get it right.

Medina got the wave of the event so far in his Round 5 heat against Japan's Tokyo Olympic silver medalist Kanoa Igarashi, a 9.90 out of 10 that was, if anything, underscored.

Taking off deep, Medina pumped through an enormous tube and signaled to the judges that he thought it was worth a 10 before flying into the channel. Most of those on the flotilla of boats and Jet Skis watching meters away screamed in agreement.

Medina backed it up with a 7.5 for a 17.4-point total to cement him as a favorite to win gold.

"I never imagined we could get waves like this in the Olympics," Medina said. "I'm comfortable when the waves are good and as long as it's like this, it's good for everyone... today was a good day for sure."

FLORENCE OUT

One heavyweight clash worthy of a final, John John Florence of the United States taking on Australia's Jack Robinson, was brutal and tense rather than spectacular as both tube-riding maestros struggled to get the right waves.

Robinson prevailed 13.94 points to 9.07, knocking the World No. 1 surfer from Hawaii out of the competition.

"We didn't get it easy. At the start of the heat, I got dragged over the bottom and then almost had a two-wave hold down," said Robinson, coming up from a wipeout just before the next wave smashed him.

Robinson agreed surfing might be the most dangerous sport in the Olympics in conditions like these.

"Every other sport is in a court or a stadium, and we're in the ocean which is the biggest, most powerful source of life that we have on this planet," he said.

"The wave just so powerful. It doesn't relate to any other sport, you know what I mean? Maybe an avalanche or something coming down your head on a mountain that's similar... it's so dangerous."

'JUST INSANE'

Earlier, Tahiti's Kauli Vaast, surfing for host nation France, eliminated American Griffin Colapinto.

"It was just perfect," said Vaast, who has had more than his share of jaw-dropping waves at "The End of the Road" as Teahupo'o is known. "There are some 10 foot, perfect 10 foot (waves) coming up, offshore wind, two guys out, beautiful sunny days -- just insane."

Japan's Reo Inaba knocked out Brazil's two-time world champion Filipe Toledo, whose countryman Joao Chianca triumphed over Morocco's Ramzi Boukhiam in the round's highest scoring heat -- 18.10 to 17.80.

"I'm really upset because I know that I could have brought gold for Morocco in these types of waves," Boukhiam said. "It was possible, because I love this (expletive), man.

"Even though I lost, this is going to be one of the best heats for my life."

The women's Round 3 was scheduled to follow the men's, but conditions quickly turned with howling winds and pouring rains lashing the lineup, forcing the competition on hold, probably for a couple of days.
