WBA/IBF middleweight titleholder Gennady Golovkin’s second-round KO of Dominic Wade on Saturday was the most watched HBO boxing event in 2016 with 1,325,000 viewers, according to K2 Promotions, which represents the Kazakhstan native.

“We’re very happy with these ratings for Gennady which have continued to see extraordinary growth since his first fight on HBO in September 2012,” said Tom Loeffler, executive director of K2. “As he continues to sell-out arenas in America and garner the top sponsorships in boxing with the Jordan Brand, Apple, Tecate, Bijan and Samsung, among others, it’s clear that Gennady is one of the most marketable fighters in the world.

“Selling out arenas in New York City and Los Angeles is very rare for a boxer, but Gennady continues to transcend the sport of boxing as he crosses over to the mainstream.”

Golovkin’s victory over Wade (18-1, 12 knockouts) took place in front of a sold-out crowd of 16,353 at The Forum in Inglewood, California. It was the highest selling boxing event in the storied history of the arena, according to the K2 press release, and the highest in California in the last seven years. Along with his previous two fights in Los Angeles, Golovkin (35-0, 32 KOs) has now sold 38,408 tickets in his adopted home of California, by far the most of any other boxer over the same period.

The knockout of Wade was Golovkin’s 16th WBA title defense and his 22nd straight knockout victory. He retained his WBA, IBF, IBO and WBC “interim” middleweight titles.

In the co-main event on Saturday night, Roman “Chocolatito” Gonzalez (45-0, 38 KOs) defended his WBC and RING magazine flyweight titles with a dominant 12-round unanimous decision over world ranked McWilliams Arroyo (16-3, 14 KOs). The victory by THE RING’s No. 1 pound-for-pound rated fighter drew 1,001,000 viewers, making it the fourth highest rated HBO fight in 2016.

“Roman performed in spectacular fashion and with this rating proved that he is more than capable of headlining his own show,” said Loeffler. “We look forward to working with HBO and Mr. Honda of Teikin Promotions on putting together his next world title defense.”
