Masayuki Ito’s Underdog Title Win: Christopher Díaz Outboxed
On July 28, 2018, Masayuki Ito defeated unbeaten Christopher Díaz by unanimous decision in Kissimmee, Florida, to win the vacant WBO junior-lightweight championship. The victory was the high point of a career that began without an amateur boxing background and developed through demanding professional contests.
Career Milestones and Fight Results
That chance came in Kissimmee, Florida, against Puerto Rico’s Christopher “Pitufo” Díaz, who entered unbeaten and with the crowd behind him. Ito stayed composed through twelve lively rounds and won a unanimous decision on July 28, 2018. The victory made him a world champion and gave the quiet Japanese contender a wider audience. ESPN later described a fighter still developing under trainer Rudy Hernandez, whose work with Ito continued even after he had reached the top.
For his first title defense, Ito returned home to face Russia’s Evgeny Chuprakov on December 30. The challenger arrived unbeaten, but Ito steadily took control and stopped him in the seventh round. It was a satisfying homecoming: the title he had won abroad was now defended before Japanese fans, and the stoppage confirmed that his championship run was more than a one-night surprise.
The next defense brought a different kind of test. On May 25, 2019, Ito met Jamel Herring in Florida. Herring’s height, southpaw stance, and patient pressure changed the rhythm of the fight. Ito had moments early, but Herring took over as the rounds passed and won a unanimous decision to claim the WBO belt. Ito’s reign had lasted less than a year, yet it had already carried him from an unorthodox beginning to a world title and a successful defense on home soil.
Ito continued boxing after losing the championship, returning to the lightweight division and remaining a notable name in Japan. In April 2022, he challenged Shuichiro Yoshino for regional titles. A cut from an accidental clash of heads brought the fight to the scorecards in the eleventh round, where Ito lost a technical decision. On July 28, 2022, the fourth anniversary of his title-winning night, he announced his retirement (retirement report). His professional record stood at 27 wins, four losses, and one draw, with 15 knockouts. Ito’s career remains a reminder that a fighter’s path can be unconventional and still lead all the way to a world championship.
