Zab Judah made good on his promise to take the welterweight championship of the world back to Brooklyn. Judah ventured into Spinks' hometown of St. Louis and won undisputed recognition as the best 147-pounder world by ninth round technical knockout in front of more than 20,000 screaming Spinks fans.  After a tactical first six rounds, Spinks may have caught a break at the end of the seventh round. He was hurt by Judah's punches and went down to the canvas.  The call could have gone either way, but referee Armando Garcia ruled it a slip. The action intensified in the eighth, as Judah tried to walk  through Spinks' jab to land power punches and Spinks responded with some good shots of his own. In the ninth round, Judah caught Spinks with an overhand left and then put him down with a right. Spinks got up, but his head was not clear, and Judah backed him against the ropes, raining punches on the soon-to-be ex-champ.  Two times, Judah stopped punching and invited Garcia to stop the fight.  The referee declined, but changed his mind after Judah landed one more big punch. The ending spoiled Spinks' homecoming to St. Louis after Spinks made a spectacular ring entrance accompanied by hip-hop star Nelly. Spinks and Judah entered the bout 1-2 in the Boxingtalk ratings, and will flip-flop positions. Tonight marked the first decisive loss of Spinks' career. His 34-3 record includes disputed decision losses to Michele Piccirillo and Antonio Diaz. Spinks made $1.2 million for the bout compared to a paltry $100,000 for Judah.
