Mr. Wolff teamed with Joe Garagiola on NBC-TV’s baseball Game of the Week in the early 1960s. He was a broadcaster for Madison Square Garden for more than 50 years on staff and as a freelancer, calling Knicks and Rangers games, college basketball and the Westminster Kennel Club Dog Show. On radio, he called the last half of Larsen’s perfect game for the Yankees against the Brooklyn Dodgers, and the sudden-death overtime N.F.L. championship game between the Giants and the Baltimore Colts.
