Dallas, St. Louis and Baton Rouge have it over RFK Stadium for a Sugar Ray Leonard fight in May, never mind the pleasantries by Leonard's adviser Mike Trainer--after last month's easy one in Reno--that a Washington bout would be nice. But maybe you'll catch it live, network prime time.

Philadelphian Roger Stafford is the near sure opponent if he gets by David Madrid tonight in Atlantic City. Trainer, tying up loose ends, says he hears nil from Bob Sigholtz, who runs RFK, and TV's desire for a fairly early date (Friday, May 14 or 21) dims prospect of D.C. action . . .

Los Angeles remains site of its own fight. National Football League rebuffed by 9th U.S. Circuit Court of Appeals, San Francisco, yesterday: no change of venue for Oakland Raiders-L.A. Coliseum v. NFL. Reaction from league HQ: a motion for restricted press coverage in federal court and a statement: "The NFL is ready to go to trial on March 15. However . . . there is no city in the United States less appropriate . . . than Los Angeles, where the jury . . . has a vested interest in the verdict."

Japanese--what recession?--make second straight day's news on LPGA tour. Ayako Okamoto extracted $18,750 first prize in the Arizona Copper Classic, but Mazda, the car company, injects $1.5 million into the circuit's prize structure. Three-year deal brings $125,000 bonus for golfer of the year on down to $3,000 for 10th place; $200,000 extra (perhaps $5,000 cash or an auto) to weekly tournament winners; a climactic triple-bonus-value Japan Classic in Tokyo (Nov. 5-7, in '82). And it's retroactive to start of 1981.

One Badger State coaching report pans out--Zeke Bratkowski leaving Green Bay NFL staff for Baltimore to coordinate offense and coach Frank Kush's quarterbacks (Bert Jones?). As for one that U. of Wisconsin eyes Boston College's Tom Davis to relieve Bill Cofield as basketball coach, Davis pleads "no contact" . . . WTTG-TV-5 picks up Thursday's Georgetown-Providence. Can Hoyas win a third straight 60-42 game? . . . Dave Schellhase, mid-'60s national scoring champ at Purdue, will coach Indiana State hoops replacing resigned Bill Hodges, '79 coach of year . . . UNC-Charlotte axes Mike Pratt.

Virginia's Terry Holland got a much nicer surprise yesterday in Charlottesville than Saturday in College Park. Campus and community overwhelmed coach, wife Ann, daughters Kate and Ann-Michael (dog Dean stayed home?) with a "Thanks, Terry" breakfast in University Hall. "Thanks," Holland told 400 well-wishers and gift-givers, "very much for being family" . . .

Ralph Sampson lone repeater on U.S. Basketball Writers all-America. Other selectees: James Worthy and Sam Perkins; Terry Cummings, Kevin Magee, Dale Ellis, Ricky Pierce, Paul Pressey, Bill Garnett and--yes!--Hoya Eric Floyd. Eleventh man is Landon Turner, honorary; might have been his banner year at Indiana but for that crippling wreck.

Tracy Austin, after six weeks off with sciatica, set to try Avon circuit and top seeded at L.A.: set back another week. Dining out with family when, oops, a busboy dropped a pot of boiling water on her left arm and stomach. Arm burns forced withdrawal . . . Ex-Dodger Reggie Smith: signed by Giants.
