Sugar Ray Leonard
Arum kept producing big-scale undercards and superfights, including the Hagler–Sugar Ray Leonard bout, the Sugar Ray Leonard vs. Thomas Hearns 1989 rematch, Evander Holyfield vs. George Foreman, and many others. Some of Arum's superstars from the 1990s include former world flyweight champion Michael Carbajal, six-division world champion Oscar De La Hoya, eight-division world champion Manny Pacquiao, and three-division world champion Erik Morales. Arum also promoted the legendary champion Julio César Chávez in his later years of boxing.
