Nicknamed "The Knock-Out King" for his exceptional knockout power, Bailey is considered to be one of the hardest punchers in boxing history.
[1] Bailey turned pro in 1996 and won his first 21 fights by knockout, including the WBO Light Welterweight Title with a 1st-round KO over Carlos Gonzalez in 1999.
In 2006, Bailey defeated Lenin Arroyo, Santos Pakau, Juan Polo Perez and Russell Stoner Jones to get the right to fight Shawn Gallegos for the IBA Intercontinental Light Welterweight title.
Bailey lost his IBF welterweight title against Devon Alexander as a main event on Showtime Championship Boxing.
He then won three straight fights, culminating in a knockout win over Shusaku Fujinaka for the WBO Asia Pacific Welterweight title, before a loss to Jeff Horn on April 27, 2016.
