Floyd Joy Mayweather Jr. is an American boxing promoter and former professional boxer who competed between 1996 and 2017. He retired with an undefeated record and won 15 major world championships from super featherweight to light middleweight. This includes the Ring magazine title in three weight classes and the lineal championship in four weight classes. As an amateur, he won a bronze medal in the featherweight division at the 1996 Olympics, three U.S. Golden Gloves championships, and the U.S. national championship at featherweight.

In combat sports such as boxing and MMA, an orthodox stance, also known as a northpaw stance, is one in which the fighter places their left foot in front, thus placing their left side closer to the opponent. Because it places the right side in the rear, the orthodox stance can allow for more rotation and distance to accelerate right sided strikes, in turn generating more power. This makes it the most common stance in boxing, as well as MMA, and primarily used by right-handed fighters.
