ATLANTIC CITY, N.J., Dec. 14 (UPI) -- Cory Spinks upset Ricardo Mayorga Saturday night to become boxing's undisputed welterweight champion.
Also, in the main event, undisputed middleweight champion Bernard Hopkins battered William Joppy to retain his titles.
Spinks, the son of former heavyweight champion Leon Spinks and nephew of former light heavyweight and heavyweight champion Michael Spinks, stole the show before a sellout crowd of 12,364.
'I did what I had to do - box," Spinks said. "I kept my head and did what I had to do."
Hopkins, making the 17th title defense of a share of the middleweight crown, wore down Joppy, winning on the inside and landing. In the final round, he gave Joppy a savage beating, unleashing power shots to the head.
Also, John Ruiz captured the interim WBA heavyweight belt, beating Hasim Rahman; Travis Simms scored a fifth-round knockout of previously undefeated Alejandro Garcia of Mexico to capture the WBA super welterweight title, Zab Judah needed one punch to stop Jaime Rangel to retain his WBO 140-pound title.
