Washington is entered in the 12th annual United States Youth Games starting today in Detroit and ending Friday.

The Washington team, 76 youths age 9 through 15, will compete in track and field, bowling, basketball, tennis and swimming against teams from other cities.

Washington finished first overall in 1969, 1971 and 1972. Its track and field team placed first from 1969 through 1974.

George McGlnnis returned from a month's vacation back home in Indianapolis-still a Philadelphia 76er. The tentative NBA trade of forward Bobby Jones is hanging fire; both pricipals evidently holding fire; both principals evidently holding out for something to make it worthwhile for them to sign away their no-trade contract clauses. Sixer GM Pat Williams says he will have no comment until the deal materializes or blows up-by that time, if rumors from Bloomington, Ind., have substance, Williams could have escaped the 76er madhouse himself. He's said to have applied to Indiana U. for the athletic director vacancy left by Paul Dietzel's hop to LSU...

The bit about Los Angeles Coliseum landing another NFL team to replace the Rams come 1980 took on a slightly more serious cast yesterday. Jack Heller, an investment broker representing Iranian and European interests who reportedly bid $50 million to buy the Rams a few weeks ago, said his group is close to closing a deal that would bring "either an existing team or a new franchise"...Sad commentary on the times, in accepting the post of athletic director at Kansas, Bob Marcum (leaving as associate A.D. at Iowa State) felt constrained to say that his department will "work within the rules of the university, NCAA and Big Eight"...Pat Costello, who broke the women's bowling record with a three-game block of 863 (298-266-299) during the current Metroplex Open in Dallas, is the Union City, Calif, Costello, not frequent WPBA champ Patty Costello of Scranton, Pa., and formerly of New Carrollton in Prince George's...

Pete Rose's chase of Joe DiMaggio meant a box-office bonanza capped by the estimated $128,000 gate boost in otherwise expectable gate in Atlanta on Monday night and also featuring: In Philadelphia (games 32 and 33), attendance up 11,180 a game over normal: In Montreal (games 34,35,36) averaged 8,317 above normal, and in New York (games 37,38,39) Rose drew 31,328 a date against a Met average of 14,503-a $184,737 gain in Shea Stadium gross, not counting concessions. Cincinnati, of course, also topped its usual hefty crowds and the Reds as a road team benefited also-visitors' takeout in baseball nowadays is 38 cents per paid admission...

The Pittsburgh Pirates probably felt worse than anyone but Rose's teammates and friends. If he had taken his streak through 56 games it would have set up his shot at the magic 57 in Pittsburgh Aug. 14. And could the Bucs have used the magnet: They have had such lousy attendance this year that owner John Galbreath and son Dan the club president were behooved lately to fend off reports that they were ready to sell and get out of baseball or move the team. Bring back Bob Prince?
