One Yankee, still with time to dive into Friday's free-agent pool, who won't: Lou Piniella. A .438 World Series batter at 38, he'll be in his 40s before expiration of the New York AL contract he signed yesterday, saying, "I feel the danger period for an athlete is the mid-30s.

George Steinbrenner seconds that -- "Lou is a player who can rise to the occasion" -- and will pay him an estimated $200,000 a year to prove it. . . .

Two first basemen named R. Jackson could turn up for reentry. Ron Jackson, short-time Tiger (and a mere Type C!), is close to signing a $2.5 million, multiyear Detroit contract but may first test the draft, says agent Abdul Jalil.

Dick Williams visits San Diego, says he would manage Padres "if they feel I haven't overpriced myself." He wants maybe $150,000 a year. And maybe autonomy enough not to take the rap that boss Ballard Smith laid on Frank Howard: "stubborn" refusal to communicate with the front office. Better known as "apple polishing," retorted Hondo . . . Jim Frey, Kansas City ex-manager, is back at what he maybe does best: batting coach, with the Mets of old Oriole colleague George Bamberger . . . The Dick Howser Royals yesterday became the first major leaguers to lose five straight on postseason tour of Japan; a Yomiuri Giant-Seibu Lion squad trumped two George Brett home runs, 7-3.

A Dallas grand jury declines to indict the man, 26, accused of shooting Cowboy injured-reserve tackle Don Smerek in an Oct. 11 parking lot tussle. Could have been self-defense, jurors may have decided after hearing witnesses who said Smerek, 6-7, 255, picked the fight that got him wounded in the chest . . .
