Joseph Parker's secured his first knockout victory in over two years

The Kiwi boxer has floored Mexican-American Alexander Flores in the third round of their heavyweight bout in Christchurch.

Parker says he wanted to assert his front foot dominance.

He says he was patient and only moved when he needed to use power and be aggressive.

It's Parker's first win of the year, following losses to Anthony Joshua and Dillian Whyte.
