Thurman (Grumpy) Munson's day is coming: Sunday, Father's Day.

The National Father's Day Council named the Yankee catcher baseball father of the year - almost simulataneously with publication of a Sport magazine article chronicling how Munson's relations with his dad were so bad that, at last report, he didn't even know his current wereabouts.

Youngest of four children, Munson said he got little affection, much criticism, hardly any praise from his father. Now that Thurman has grown up to be a father of daughters age 8 and and a hyperactive son, 3, his wife Diane expressed puzzlement at his selection.

Contacted by the New York Times recently when she learned of the award, Mrs. M. said from their Canton, Ohio, home: "How do they know he's good father?" Evidently because she spread the word while he gruffly went about his business, and, as she offered, "He said maybe it was the way he carried on all winter about wanting to be tradded so he could be with his family". . .

Old-timer's day: Tonight at Rosecroft, Willie Webb Remembrance Night, feautring Webb, 86. He drove the winner in the first race when the Oxon Hill harness plant opened May 27, 1949; his Quick Trip, national 2-year-old champion of 1947, is buried in front of Rosecroft's Tote board; he still trains standardbreds in Kilmarnock, Va, ad he will drive a sulky in the post parade to a pace named in his honour . . . Tomorrow, 8:30 p.m., Shoreham Americana Hotel terrace, a black-tie birthday salute to Eddie Rosenblum, 85. With Morrie Siegel as M.C. and old pitcher Milton S. Kronheim Sr. (who turns 90 on Oct. 2) as chairman, tribute will be expressed for still acitve attorney Rosenblum, former director of the Jewish Community Center, a founder and charter member of the AAU, author of the bill that legalized boxing in the District in 1934, etc, etc. . .

And Glenn (Choo Choo) Cunningham, the good sport from Vienna, proves the running boom is merely cyclical with clippings from 1928 about the City Club 15-mile he and 59 others ran fom G Street downtown, out Connecticut and Wisconsin avenues and around by way of the Mall and parks, full entry list appearing in the paper.

Bill agree of Fort Meade won it, but under the entry list, another item of 1928 caught our eye: "Letter Reaches Golfer at 'Chubby Chase' Club." It relates how the mails promptly delivered to one of the guests in a Chevy Chase Club invitational golf tournament a note addressed by his son, 10, to him care of "Chubby Chase Golf Club, Washington, G.T.," and reading: "Dear Daddy; Hope you're having a swell time. Also hope you make lots of money, so that you can buy me a pony when you come home". . .
