Quadruple champion


A Grand Slam Champion, also known as a Quadruple Champion, occurs in different sports when a competitor wins four crowns, titles, medals, belts or another distinction. The definition varies depending on the sport.

Boxing

In boxing, a quadruple champion is a boxer who has won world titles in four different weight classes.
The first ever man to earn that enormous distinction was Thomas Hearns on October 29, 1987. Hearns won his first four titles at the following divisions: Welterweight, Light Middleweight, Middleweight and Light Heavyweight. By later winning a super middleweight title, he also became the first to win world titles in five weight divisions.
The second man was Ray Charles Leonard, who on November 7, 1998 won his first championships at Welterweight, Light Middleweight, Middleweight, Super Middleweight and Light Heavyweight. There are five titles in five divisions but his case is extremely rare: Leonard fought for two different belts in two different weight divisions the same night: Super middleweight and Light heavyweight against Don Lalonde so any of the titles can be attached as his fourth title.
The legendary Leo Gamez was the first champion to win all the lightest divisions from Minimumweight, Light Flyweight, Flyweight to Super Flyweight. Gamez did it on October 9, 2000.
Some boxers have managed to win four titles and become Quintuple Champions.
