Don't bet the rent, but - a year since plans were annouced for a 1977-78 start - plans are a-firming for a Women's Pro Basketball League in 1979 and Tara, Too Tall and such talents may have a place to play, for pay, after college.

WBL President Bill Eyrne of Columbus, Ohio (where he also is president of - going into its second year a-burgeoning - American Professional Slo-Pitch Softball League), reports that franchises have been awarded to Des Moines and St. Louis. And, among other prospects to make it a 12-team league, to play 34-game schedules beginning in Mid-December, is Washington-Baltimore.

Gary S. Minninsohn, a Silver Spring attorney, is "working with several people from the area in a joint venture toward purchasing a club."

The women's league plans a draft in July, conducted by an outfit called National Scouting Association that has been shadowing the colleges and AAU action - but no undergratuate hardship applications, WBL doesn't want to disrupt the development of the game at college level. Better luck to 'em than the men's Eastern Basket-ball Association had attendencewise in its try here this winter . . .

Another reason, Wisconsin's William Proxmire told his Senate collegues yesterday, for Congress not renewing federal aid to New York City after June: we taxpayers would be making the Yankees richer so they could continue "to take the best players away from the rest of us."

Proxmire noted a New York Times report from the N.Y.C. comptroller that by charging off $839,000 in maintenance to the city that spent $48 million refurbising the Bronx ballyard, the baseball team got away with paying only $150,000 stadium rent to the city on a 1977 gross of $14 million.

The year before the maintenance clause enabled the city, instead of receiving $800,000, to wind up owing the Yankees $10,000. Said the senator head of the Banking and Urban Affairs Committee, among "knuckle-headed ripoff" and other goodies:

"Maybe this country would stand for seeing the richest man his town rob an orphan's piggy bank and do it on network TV in prime time without outrage. But to be a party through New York City's dimwitted contract to making the Yankees richer still so the yankees can pay the huge salaries to take the best players away from the rest of us - that no red-blooded baseball fan outside New York itself will ever permit."

Promire roots for the Milwaukee Brewers, 100 to 1 in Vegas to win the pennant; the Yank are 5 to 7 . . .

And the New York Apples of World Team Tennis hired the Yankees' former public relations director yesterday, name of marty Appel . . . And the International Olympic Committee, partly as a rebuff to UNESCO's recently evinced interest in extending its political wing to cover sports, issued and 11-page manifesto in Lausanne, setting out eight points, in warning governments not to meddle with sport for political ends. If at first you don't succeed, etc. . . . NBA Commissioner Larry O'Brien, on sticking Knick Coach Willis Reed a second $1,000 fine for his season-long and intensifying drumbeat against the officiating: "It is now quite apparent that you feel no obligation to abide by league rules of your own personal commitments . . . A coach cannot be allowed to encourage fans to act in a manner which could ultimately result in a major incident, and this has been the apparent thrust of your admitted public statements" . . . Bob Trumpy, retiring from the Cincy Bengals, says sthe hardest hit of his 10-year NFL career came last season, courtesy of Pittsburgh's Mel (Clean Hands) Blount. Beginning a new career as a Queen City sportscaster, Trumpy joked (?), "Mel called me and said he was playing next year,so I told him I wasn't" . . .
