"A big part of the strategy is to determine when to go down, and when to come up," Savu said. "Anticipation is key, especially with the lack of oxygen."
In just a few months, he and Docampo have already established a silent rapport.
"I know how long Andrei can hold his breath for, and I know when he's going up, so I have to go down," Docampo said. "I have an idea of when my teammates are going to be running out of breath."
That makes it pretty hard to check someone against a pool wall. But that doesn't mean the sport is void of incidental contact.
Docampo said he's suffered plenty of bruises.
"You get kicked underwater, sometimes you get hit by the puck," he said. "We have mouth guards on the snorkels so if you take a puck in the mouth, you don't hurt yourself."
But Gokhale said the playing environment mitigates any pain.
"Because you're underwater, the impact of getting hit is almost dulled down."
Underwater, but still underground
Despite its relatively low profile in the United States, the sport started almost 50 years ago as a way to keep a British sea-diving club together during the frigid winter months.
"The whole club could disintegrate if the members were only able to plod up and down a swimming pool for six months," founder Alan Blake wrote. "I had to put something together to keep the branch up to strength for next summer."
His desperation spawned octopush, a game with eight players pushing a lead disc underwater. The sport later became known as underwater hockey.
It's now a fiercely competitive sport in countries such as Australia, New Zealand, South Africa, the Netherlands and Canada.
Later this month, elite players from 19 countries -- including the United States -- will compete at the Underwater Hockey World Championship in Hungary.
Despite its international popularity, underwater hockey has yet to rise to the surface of mainstream sports in the United States -- perhaps because it can't draw thousands of spectators like football or basketball.
"Underwater hockey is not a great spectator sport. You cannot see the game from above water, and good underwater video coverage is difficult," said Jen Gall, a board member with USA Underwater Hockey.
And, unfortunately, "the game cannot be 'picked up' on the corner lot."
But it's gaining popularity in places like San Francisco, which has a YMCA program and two city youth programs, Gall said.
Roger Bacon High School in Cincinnati, Ohio, has one of the few -- if not only -- high school underwater hockey teams in the country.
Nationwide, roughly 1,000 players participate in about 50 clubs, all of which are co-ed, Gall said.
It took awhile for Savu and Nicole Mazouchova to get the sport going in Atlanta. Exactly two players showed up to the Swordfish team's first practice: the two founders.
Now their club has a roster of dozens, including Morgan, a grandfather who won a gold medal in his division during the national championships in Washington last year.
At 52, he wasn't even close to being the oldest competitor on his championship team. That player was 76.
Now Morgan is bent on becoming the oldest championship player in underwater hockey, which means playing for at least another 24 years.
"Somebody's got to take that record away from him," he said.
