Via Ken Hissner: Among the active fighters today, the IBF, WBA and IBO world middleweight champion has just secured his 21st defending title leading all active fighters.
Only five world champions have at least ten defenses. On April 9, Golovkin unified the titles in knocking out former WBA Super World Middleweight champion Ryota Murata of Japan in Saitama, Japan.
Back in December 2010, as interim WBA champion, Golovkin won the WBA title, knocking out Nilson “Blade” Julio Tapia of Colombia. Two games later, he added the IBO Lajuan Simon title of Philadelphia. In October 2014, he had another temporary WBC title knocking out Marco Rubio, who couldn’t lift weights.
In December 2016, Golovkin got another WBC World title knocking out Kell Brook. In December 2018 he drew an unwarranted draw against Saul “Canelo” Alvarez which everyone but two referees assumed he had won.
Golovkin lost the decisive right to Alvarez in the rematch and waited four years for the return leg. Two matches later, he defeated Sergiy Derevyanchenko to win the vacant IBF and IBO middleweight belts.
The next highest in defense is the WBA, WBC, WBO and IBF Super Middleweight champion Saul “Canelo” Alvarez of Mexico, with seventeen defenses. Six is the WBA Super Welterweight champion and five is the WBC Middleweight champion. Then, moving up to super-middleweight, he won all four of the organization’s titles, making six more defenses out of a total of seventeen defenses.
WBO World Welterweight Champion Terence “Bud” Crawford of Omaha, Nebraska, ranked third in defense. In March 2010, he won the WBO lightweight title defending it twice, and in April 2015 he defended the WBO lightweight WBO title defending it six times. In June 2019, he claimed another WBO Welterweight title, defending it five times out of thirteen defenses.
Tied in third in defense is the current WBA and IBF World Bantamweight Champion Naoya “Monster” Inoue Japanese. In April 2014, he won the WBC World Light Flyweight title in April 2014 and defended it once. In December, Inoue won the WBO Super Flyweight belt, defending it seven times. He won the WBA Bantamweight title in May 2018, defending it once. In May 2019, he won the IBF Bantamweight title four times out of 13 defenses.

He won the WBO and WBC Bantamweight titles in February 2011, defending them once. He won the WBO Super Bantamweight belt in February 2012, defending it three times. He lost the title, and two fights later won the WBA Super World Featherweight title in May 2014. He lost that title in his first defense.
