He held multiple world championships in two weight classes, including the undisputed welterweight title from 2003 to 2005, and the IBF junior middleweight title twice between 2006 and 2010. Additionally, he challenged once for the lineal middleweight title in 2007. Early life and amateur career Spinks is the son of former world heavyweight champion Leon Spinks and nephew of former world heavyweight and light heavyweight champion Michael Spinks. He has an amateur record of 78–3, and won the National Golden Gloves and National Police Athletic League welterweight titles in 1997. Professional career Undisputed welterweight champion Spinks went 29–2 in his first 31 contests, only losing to Antonio Díaz (regarded as a controversial decision by some boxing analysts and ringside observers) and Michele Piccirillo, whom he defeated by decision in a re-match.
