The first real showdown between Arnold Palmer and Jack Nicklaus epitomized their long-time battle. “Arnie’s Army” had occupied Oakmont, Pa., to cheer on their hometown hero, the 32-year-old, three-time-Masters-winning Palmer, in the 1962 U.S. Open. Nicklaus, then 22, was their whipping boy, heckled with calls of “Fat Guts” and “Ohio Fats.” As Ian O’Connor notes in his book Arnie & Jack, sportswriter Jerry Izenberg said reporters “felt like they were covering a lynching.” But Nicklaus stayed focused and won his first major. “Whatever Arnie did, Jack just did a little better,” Palmer’s brother Jerry said.
