Curses, foiled again. Last summer, Col. Bob Sigholtz of the Armory Board told the good folk of then nation's capital that RFK Stadium soon would boast the nation's first computer-controlled, full-color, animated-display scoreboard. Well, look westward.

Word is in that San Diego Stadium is sporting what the manufacturer (American Sign & Indicator, Spokane) calls the nation's first computer-controlled, full-color, animated-display scoreboard. The $1 million price tag to the City of San Diego will be covered by sale of advertising space, and the 'board goes into operation this month.

That's baseball . . .

And so is the Carolina League, so last call for Alexandria Dukes tryout, assemble 9 a.m. today at George Washington Secondary School, Mount Vernon and Braddock avenues . . .

Now there is only Pee Wee Reese from the Blooklyn Dodgers' 1949 pennant-winning infield: third baseman following first baseman Gil Hodges and second baseman Jackson Robin as a steward in a private club in his risburg - on whose Senators he broke Billy Cox has died of cancer at 58. In death, Mr. Cox had been working hometown of Newport, Pa., near Harinto organized baseball in 1940. After World War II, he played two years at shortstop with the Pittsburgh Pirates. Traded to Brooklyn and moved to third alongside Reese at short, he became "the greatest glove man Blooklyn ever had." Those were the words of Walter O'Malley, club president, when he traded Cox to Baltimore after the 1954 season. As an Oriole he was on his last legs and after 55 games, he quit when teaded to Clevelandin June. Career, he batted 262 in 1,058 games, with a high of 291, and a 302 World Series composite (1949, '52, '53) . . .

One who should get an extra kick out of the San Diego scoreboard is Forrest Gregg. Back where he began coaching four years ago as Charger of fensive line coach, he reviews the time in between as "unbelievable. I had a chance to be a head coach (Browns). I had cancer, underwent major surgery twice in 1976. In 1976, we had a good year in Cleveland; I was fortunate to be voted coach of the year. I had an opportunity to coach in the Senior Bowl. In '77, I was elected to the Hall of Fame - and I was fired" . . . So is the sports world rooting for another of Cleveland Brown fame to come back from cancer, as Otto Graham continues his recovery from colostomy at Bathesda Naval Hospital. The NFL and Pro Football Hall of Fame are out with updated ranking of the top 20 passers, based on minimum 1,5000 attempts, and Automatic Otto stands his ground as No. 1, with 86.8 rating points - but Oakland's Ken Stabler, newly eligible with 1,577 passes, has elbowed Graham's old Redskin pupil, Sonny Jurgensen, into No. 3 spot, 83.6 to 82.8 . . .

The U. of Cincinnati went after Mr. Bearcat Baskerball himself in hunting a coach to succeed West Virginiabound Gale Catlett, but Oscar Robertson after "several long talks," says Athletic Director William Jenike, "indicated his business interests are such at the time he can't consider it." Ohhhhh! . . . Hugh Durham, wooed away yesterday from alma mater Florida State after a nifty 12-year tenure, reportedly will draw $35,000 annual salary at U. of Georgia against a reported base $17,500 for deposed John Guthrie . . . Some scene in Providence assistant, flew in, then drove over with Athletic Director Bob Seiple of Brown U. for a news conference at which Donewald would be in troduced as the Ivy Leaguers' head hoop coach. When they arrived, Donewald announced he had too many doubts and was going back to Indiana.

Affirmed has a rider, and a good one in place of suspended Steve Cauthen for tomorrow's Santa Anita Derby: Laffit Pincay, making a quick comaback from being knocked unconscious in a spill Thursday . . . Red Rum's last hurrah in the Grand National at Aintree, Liverpool, England, sadly will not be a contender to win the race he has dominated so often. Trainer Ginger McCain decided Rummy's heel bruise too tender for the 4 1/2 mile ride today over 30 towering barriers. The 13-year-old bay gelding will be retired, after, if all is well, leading the field of 39 out to the startin the post parade . . .
