LONDON — The GGG knockout streak continues.
Golovkin, the much heavier puncher, punished Kell Brook for nearly five rounds before unloading a brutal onslaught of blows against the game welterweight titleholder. That sent Brook’s trainer, Dominic Ingle, onto the ring apron to throw in the towel in the fifth round Saturday night at the sold-out O2 Arena.
Brook’s home-country crowd had come to see if he could pull off one of the biggest upsets in British boxing history, a list that includes Randy Turpin’s 15-round decision against Sugar Ray Robinson to win the middleweight title in 1951, Ricky Hatton’s 11th-round knockout of Kostya Tszyu to win the junior welterweight title in 2005, and Tyson Fury’s decision win over Wladimir Klitschko 10 months ago to win the heavyweight title.
But Brook (36-1, 25 KOs) was overpowered by perhaps the best puncher in boxing. Brook took some thunderous punches and never went down, but he seemed shaken by many of the punches Golovkin landed.
Golovkin (36-0, 33 KOs) retained his middleweight title for the 17th consecutive time. The middleweight division record is 20 straight defenses, set by the great Bernard Hopkins, who was ringside as an HBO analyst.
Golovkin, who has not gone the distance since winning an eight-round decision in 2008, notched his 23rd knockout in a row and increased his division-record knockout percentage for middleweight title fights to .917.
