Gennady Golovkin successfully defended his WBA middleweight title with a commanding performance against Britain's Martin Murray on Saturday, stopping him in the 11th round of a one-sided contest.

Making his third title defense, Golovkin has stopped his last 19 opponents, and is unbeaten in 32 fights with 29 knockouts.

Prince Albert of Monaco was among the crowd as Murray withstood some heavy punishment, and showed tremendous courage to try to trade with the hard-hitting Kazakh.
