The truth will out, sometimes. Disco Dan Ford popped his cork and it will cost the California Angels three days of his services in American League West pennant race II.

Umpire Dale Ford, obviously no relation, caught outfielder Ford using an illegal baseball weapon Friday night at Cleveland when the top of his bat flew off, followed by cork filling. AL President Lee MacPhail examined the physical evidence and yesterday decreed three-day suspension and "minimal" fine -- no doubt bringing sneers from suspicious Orioles who'd tried to get the goods on Ford in Baltimore, raising guffaws from many a spitball pitcher, and sending some other hitters repairing to their bat racks . . .

George Allen is everywhere! Tonight, as chairman of the President's Council on Physical Fitness and Sports, the Ol' Coach will be host for the council's silver anniversary, black-tie awards dinner at the Shoreham. Twenty-five distinguished Americans to be bemedaled . . . Oops, local hotelwise, it's this Saturday for the Adrian Dantley wedding do at the Capital Hilton . . .

Capital? Welcome back to the active roster of the club that perennially leads the NHL in man-hours lost to injury Caps P.R. chief Lou Corletto. A week ago, G.M. Max McNab received a message that Corletto wouldn't be in to work that day; had fallen and taken four stitches. In hockey, that's not much of a cut, but McNab better understood Corletto's absence when he learned it was 40 stitches -- and could have been worse. Seems Corletto, chasing youngsters who had been banging on the door of his house, tripped in a construction area and was pierced in the chest by a flag stake. It just missed his heart and lung . . .

University of the District of Columbia, which recently brought in "Wendy" McGriff, a man, to coach women's basketball, now has hired Cheryl Roberts, a woman of 23, to assist Coach Wil Jones with men's basketball. Roberts, a 1980 Shepherd College graduate and D.C. native who has been working in the metro area as a recreation therapist, gradually will work into regular coaching and scouting duties while overseeing Firebird academic progress . . .

The Monday Morning Quarterback Club, a durable Washington institution, has become just the Quarterback Club now that the Redskins are tied up with Monday practices. So the season's first meeting for Bob Geoghan's QBers is set next Tuesday, in the Touchdown Club. He hopes to land Billy Kilmer . . . That would be the day after Kilmer, Sonny Jurgensen, Red Auerbach, Lefty Driesell, Larry Brown, Brooks Robinson, etc. help the B'nai B'rith Sports Lodge of Greater Washington make a big splash of its first charity pro-celebrity-amateur golf and tennis tournament. Last call to get in on the Monday action at Indian Spring Country Club; contact Arnold Heft, Hyattsville, or Indian Spring . . .

Locals Fred Borchelt and Andy Sudduth earned silver medals on the U.S. four-with-coxswain crew at last week's world rowing championships in West Germany. Bob Spousta, T.C. Williams High coach, was over there, too, to help root the Yank eight to the bronze, behind U.S.S.R. and Britain but ahead of East Germany . . .

NFL popularity holds: record opening weekend attendance, 866,788. That's 29,000 more than the mark set in 1979 and fewer than 9,000 shy of league record for any weekend, set last Oct. 12-13.
