The San Diego Padres have no intention of meeting Dave Winfield's demand for a 10-year, $15 million contract but they object to other major league teams bending the ear of the big outfielder whose contract doesn't expire until 1980 season ends. Ballard Smith, Padre president, remarked that he knew Montreal Manager Dick Williams and somebody from the New York Yankees' publicity staff had told Winfield they would like to have him on their respective clubs. All this has caught the ear of Bowie Kuhn -- staunch foe of "tampering" -- and the commissioner issued word yesterday he will look into the situation . . .

Smith, of course, remembers how hard Kuhn came down on Ray Kroc, Padre owner and Smith's father-in-law, for openly coveting a couple of free-agents-to-be before they became fair game last fall . . .

Today's nouveau riche baseball player: all-star shortstop Garry Templeton of St. Louis. They've worked out the long-term deal they talked of in agreeing to 1980 terms earlier this month: six years, estimated $4 million, and he can veto trade to certain clubs. The mercurial, potential-unlimited Templeton sums up: "I'm very happy. I couldn't ask for anything more." For now? . . .

Tomorrow's big-bucks guy? Mike Yastrzemski, son of Carl, homered in his second game as a Florida State freshman -- then in game three, Sunday, whacked a three-run, ninth-inning home run to beat Miami. g
