He was in white, all white, down to the tips of his dancing shoes, with a baby blue silk waistband added to the flair.

And she was in blue, all blue, from her blue stockings to her body tights to her blue eyeliner.

And when they came out on the floor - no question - they were the disco king and queen of Washington.

Right from the start Linda Rodriguez was up on Craig Yee's shoulders, legs extended as he twirled her, and then she swept down and through his legs in a move as smooth as his silk sash, Yee spinning around, pulling her up before they stepped into a Latin hustle.

"Oooh, baby," someone in the crowd cooed.

Yee, 24, and Rodriguez, 22, two professional dancers from New York, won the "Disco Duel Contest" - and $2,000 - at the Plum disco, 1119 21st St. NW, early yesterday morning, beating eight other couples to lay claim to the Washington D.C., disco championship.

The contest began in early April and after eight preliminary rounds and a semifinal heat, the original group of 70 couples had been reduced to nine. By 12 a.m. yesterday only Yee and Rodriguez were strutting their stuff at the Plum, the disco "Where the Big Kids Play," according to the advertisements.

"I don't want to do nothing but dance," Yee said as he stood in the hallway at the club, shrugging off the kisses from admiring women and requests for "just once dance with me, huh, Craig, "okay?"

"I used to be an architect. I used to do some electrical work, too," Yee said. "I can make just as much money dancing and, you know dancing is the ultimate fulfilment. It keeps you in good shape, it takes commitment . . . nothing matters after I've done a good job dancing. It makes my whole day."

Yee and Rodriguez's dancing was nearly perfect in the opinion of the four judges for the dance contest.They scored 193 out of the possible 200 points. With disco sounds and lights throbbing and flashing through a crowd that swelled to over 3000 persons before the fire marshal stopped people from coming in, Yee and Rodriguez never faltered. On every beat their left feet touched down simultanously through acrobatic flips and hustle variations.

"How good you are depends on how seriously you take it," said Marvin Thomas, 22, of Rockville, who came in second in the dance contest with his partner Annette Filippini, of Sterling, Va.

"And I take it seriously," Thomas said. He dances professionally with Filippini a dance instructor with Disco Step Inc.

"I got into disco when I got back from Puerto Rico four years ago," Rodriguez said. "But I always loved to dance. I remember my uncle used to take me to house parties around Brooklyn when I was Four."

Yee and Rodriguez have been dancing together for a month. They were in two dance contests before, winning once and second place in the other.

They heard about the Plum's dance contest while auditioning for Studio 78, a disco television show that will be on television in Washington this summer. Six of the 10 persons in the top five final couples in the contest were professional dancers.

In all, $5,000 in prizes were awarded to the top five couples in the contest. The prizes includes shopping certificates worth,$350, cash and a diamond ring and pendant.

Before the dancers strode out on the floor, contest coordinator Tiffany Rodill told them: "If you fall off a lift or slip, don't let it affect your whole number . . . This is like the Olympics, you can't come back."
