Former Boston Symphony Orchestra conductor Seiji Ozawa was back in town Friday to meet new BSO music director Andris Nelsons — and to cheer on the Sox, of course. The 78-year-old Ozawa, the longest-serving music director in the Boston Symphony Orchestra’s history, presented Nelsons with a Red Sox cap. (Ozawa planned to be at Fenway Park Saturday.) It had been two years since Ozawa was last in Boston, where he served as the BSO’s music director for 29 seasons. . . . Actor Bill Murray was among the duffers who hit the links Friday in Hyannis Port for the annual golf tournament benefiting the Robert F. Kennedy Center for Justice and Human Rights. Others joining Ethel Kennedy and the Kennedy clan at Hyannisport Golf Club included Maryland Congressman Steny Hoyer, actors Martin Sheen and Dennis Haysbert, and Olympic decathlete Rafer Johnson.
