You would assume that the most exciting boxer in the world would also be one of the most popular, but that unfortunately hasn’t been the case for 33-year-old Gennady Golovkin, a Kazakh phenom who was won 30 of his 33 career fights by knockout. Golovkin is, simply put, the scariest fighter in the world — but he’s struggled to land a high profile opponent and has yet to become a household name. That might change this weekend at Madison Square Garden.

Golovkin won a silver medal as a middleweight at the 2004 Olympic Games and began his professional career in 2006, but didn’t fight in the United States until 2012. He will finally make his pay-per-view debut Saturday on HBO against IBF middleweight champion David Lemieux, a dangerous Canadian fighter with 31 career knockouts.

After destroying Willie Monroe in May to win his 20th consecutive fight via a knockout, Golovkin called out middleweight superstars Canelo Álvarez and Miguel Cotto (who will fight each other in November), but Golovkin’s dominance may be scaring away elite level fighters. Why fight a man who can change the course of your career with one punch when you can settle for someone else?

Golovkin’s knockout statistics are mind-boggling. His knockout ratio (30 of 33, winning 90.9% of fights by knockout) is the highest in middleweight history. Golovkin can end a bout whenever he wants, but recently has been fighting with a more tactical style to produce a “big drama show” for fans and prove he can deliver over 12 rounds. Six of his last 12 fights haven’t made it past the third round, and Golovkin said this week he only let his win over Curtis Stevens in 2013 go to eight rounds because he wanted to teach him a lesson.

“I don’t lose control. I can beat him after the first time I knock him down. For me, it’s more important beat him, you know? Maybe, like, punish him. Beat him, beat him, beat him.”

When Golovkin decides to punish an opponent, there are few sights as spectacular in boxing.

Countless casual fans swore off boxing after they were promised the “fight of the century” between Floyd Mayweather and Manny Pacquiao and instead received a $99 snoozefest, but Golovkin is the type of fighter fans should be rallying around. Given each fighter’s history, it’s almost a guarantee that Golovkin-Lemieux will end with a spectacular KO. If you like watching Ronda Rousey-caliber beatdowns but wish the fight lasted longer than 20 seconds, Saturday’s bout is a must-watch.
