The Washington Diplomats, playing without the services of their top two scorers, fell further into the Eastern Division cellar of the North American Soccer League Saturday night, bowing to the host Dallas Tornado, 3-0.

The Diplomats, who have dropped three of their last four games, will return to RFK stadium Wednesday for an 8 p.m. match with Chicago. Washington, 6-6 overall and 3-3 at RFK, defeated the Stings at Chicago for its second victory of the season.

Against Dallas, the Diplomats entered the game without Bobby Stokes and Alan Green, the team's top two scorers, and defender Jim Steele.

Stokes was being married in England while Steele and Green were nursing strained knee ligaments in Washington.

Even without their offensive leaders, the Dips suffered more from Steele's absence in the centerback slot.

"You always miss a player like Jim (Steel)," Washington coach Dennis Viollet said. "It was the main reason they got three goals."

Viollet didn't want to pinpoint a time for the return of Steele and Green, but was pointing hopefully to the Chicago game.

The Tornado smothered goalie Eric Martin with 29 shots on goal, and he responded with 10 good saves, Dallas goals were produced by Max Thompson at 4:12, Jim Ryan at 67:08 and Gerd Stahl with 24 seconds remaining.
