Gennady Golovkin retained his unbeaten record with a stoppage of Curtis Stevens in the eighth defense of his WBA/IBO middleweight belts. The Kazakh bruiser forced Stevens' corner to step in and end the fight during a one-sided eighth round, with a flurry of punches leaving Stevens dazed and bloodied at Madison Square Garden.

Victory takes Golovkin's record to 28-0, with 25 of those wins coming by stoppage, and it was the 15th fight in a row he has won without needing to go the distance. But it will not go down as an easy victory for the 31-year-old despite him having put Stevens down as early as the second round. Stevens, whose record drops to 25-4, started slowly and could well have been finished inside six minutes, only just beating the count after being caught by a sensational Golovkin left hook. But he took time to recover and Golovkin had to fend off a fierce assault in the fourth, when he was caught by a quick left-right combination by the brave challenger.

"My plan was just to box. I know I'm the champion, my speed is better, my power is better. My coach told me to box, not have a crazy fight, a street fight. Stevens is a strong guy. After the knockdown, he started stepping back and I knew it was over. I didn't feel his power. I was able to use my right punches that we worked on in the gym to break him down. I was a little cautious of his strength but I felt comfortable in there and never felt I was in any trouble,' Golovkin said.
