The two men had met in 2012, when Diaz had out pointed Ao to dethrone the Japanese fighter of the WBC Super Featherweight title. Since then both fighters had failed to have much success, with Diaz losing the title in his first defense to Takashi Miura whilst Ao went on to have so low key wins before being knocked out by Raymundo Beltran, who failed to make weight failed a drugs test, in a Lightweight title fight.
Today both men looked like faded fighters. Ao struggled to get going, and looked unsure of himself in the first round, whilst Diaz looked slow and was dropped from a 1-2 in round 3. The slowly fought bout was mostly forgettable with Ao doing enough to take the decision 79-74, 77-74 and 77-76.
An emotional Ao spoke to the crowd after the bout, and it seems uinclear whether he will continue his career. He has been battling with injuries since his loss to Beltran and looked a shadow of the fighter he once was.
Diaz on the other told the press that he's now retired, and will be spending more time with his famile. He also said he was happy to have finished his long career in Japan, where he has now fought 5 times and gone 3-2.
Given how he looked today, retirement for Diaz was certainly the right decision.
