After handily pinning Earl "Mr. Universe" Maynard the month prior, Ladd challenged Bruno Sammartino at Madison Square Garden for the WWWF title on March 1, 1976. In 1978, he wrestled WWWF champion Bob Backlund. When the International Wrestling Association had its brief run in the New York area, Ladd lost a two out of three falls match at Roosevelt Stadium, in Jersey City, New Jersey, to champion Mil Mascaras, two falls to one (he pinned Mascaras the first fall, was disqualified in the second, and was pinned by Mascaras in the third).
