LONDON – With several news media outlets broadcasting or Web streaming every event at the Olympics, it is almost inevitable that water polo will have its share of R-rated moments.


At these Games, the most notable transition from tenacious to titillating (and quickly back again) came in the women’s preliminary-round match between the United States and Spain last Wednesday. During a particularly spirited passage of play, NBC cut to an underwater camera, hoping to show players thrashing for possession. Instead, the network gave viewers a brief bit of risqué theater as the American Kami Craig pulled at her opponent’s swimsuit and briefly bared a Spanish player’s breast for all to see.


Undeterred, the Spanish player simply grabbed back before continuing on. And while the flashing became a hot topic on the Internet and on social media, veterans of the sport were hardly surprised. After all, that sort of thing happens all the time under the water during matches, in the area that one player called a jungle.


“When I first started playing, we just wore regular suits, and I would wear two of them,” said Heather Petri, a veteran on the United States team. “At one point, they gave us the suits that swimmers use, but they’re so thin that the moment someone grabbed them, they would just go rip!”


Generally, Petri said, water polo referees call only what they can see. Fouls for grabbing or holding an opponent that can be seen above the water line are the ones that are typically penalized. What goes on underneath the water, however, is virtually impossible to see from the official’s spot on the pool deck, and trying to interpret what is going on based on how players move or react is rarely attempted.


“If they did that all the time, you’d have people just acting or simulating to draw whistles,” said Brenda Villa, the star of the United States team, which has a rematch with Spain in the gold medal match Thursday.


Asked for her most memorable moment of underwater warfare, Petri said she played about 10 minutes of a game topless at the 2000 Olympics, when an opponent shredded her suit as they grappled for the ball but play continued. Left with little choice, she just kept swimming until the next timeout, when she hopped out of the pool and shimmied into a spare.


Petri laughed as she told the story, and Villa shrugged when the tale was recalled to her, saying essentially that it is just a part of the game. “The person that invents a suit that’s not going to move is going to make a lot of water polo players happy,” she said.


The women’s players were quick to point out that the underwater fighting is hardly limited to their games. While the men’s teams do not have the same sort of family-friendly television issues, the women said, that does not mean the players do not have their fair share of dirty play.


Terry Schroeder, the coach of the United States men’s team, which was set to face Croatia in a quarterfinal Wednesday night, shook his head as he thought back to his own playing days. “When I was playing, there was a Hungarian guy and his method of guarding was to reach between my legs and grab me and pull me down,” Schroeder said. “He’d be smiling and have his other hand up in the air, but for me it was a battle just to survive.”


The biggest wrestling battles often come between defenders on one team and attackers on the other as the attackers seek to establish position where they can receive a pass to help set up an offensive sequence.


The battles for space in the water can border on epic, according to Peter Hudnut, a United States defender. “I try to describe it as a combination of judo and other martial arts mixed in,” Hudnut said. “There’s grappling and hooking, all of that.”


He pointed to his mouth. “Every once in a while,” he said, “you catch an elbow or head-butt — I caught a head-butt earlier this year in practice and lost two teeth.”


As a center on the American team, Ryan Bailey is often involved in battles near the opponent’s goal. He and the American captain, Tony Azevedo, both said they would be interested in seeing less tussling in the pool because it would promote a freer-flowing game that hopefully would be more entertaining.


“Sometimes when it becomes wrestling and fighting, no one wants to watch that,” Bailey said.


Not surprisingly, many of the women’s players feel the same way — both because of what a cleaner game might do for the sport over all as well as the impact it would have on reducing instances of water polo wardrobe malfunctions.


“Everyone likes underwater cameras because you get to see what’s going on, but as players we hate them,” Villa said. “Because you’re being grabbed, you’re being exposed underwater, and we don’t want that on TV.”
