(Reuters) - Andy Ruiz Jr. dethroned British title-holder Anthony Joshua with a stunning seventh-round stoppage at New York's Madison Square Garden on Saturday to become the first Mexican-American world heavyweight champion.

Joshua, previously undefeated and fighting for the first time in the United States, was defending his IBF, WBA and WBO titles but was knocked down four times in the fight before the referee waved off the contest in the seventh.
