The champion is a 12 year veteran who debuted in May 2006 and despite some ups and downs has been a stalwart of the Japanese scene for much of that time. In fact he would get his first Japanese title fight more than 5 years ago, when he took on the hard hitting Shinya Iwabuchi, and despite a loss he remained very relevant. Just a fight later he took on the then OPBF champion Min Wook Kim in an incredible bout in Korea. Following those losses Hosokawa has been fighting on the domestic level and scored wins over Takeshi Goda, Jumbo Oda Nobunaga Shoten Petagine and Cristiano Aoqui en route to getting his second Japanese title fight in 2016. As with his first shot Hosokawa lost, though put up a fantastic effort against Hiroki Okada and seemed to have much of his work ignored by the judges.
Although Hosokawa is getting on for a fighter he has an incredible engine, he throws a lot of leather and whilst he's not a big puncher he does make for great fights on the domestic level. He tenacity and energy is brilliant and sees him over whelming opponents with aggression and work rate. Sadly it does mean that his fights are draining and damaging but they are thrilling, exciting and great to watch. His fight with Aso last year was a Japanese FOTY contender and his 2013 bout in Korea with Min Wook Kim was genuinely thrilling. Sadly those exciting fights will take a toll on Hosokawa and his career won't have a lot longer to go, even if he is successful here against Baez.
The challenger arrived in Japan a couple of years ago to be managed from the country. The change began with an easy win in Thailand before he suffered a loss to Teerachai Kratingdaenggym at Welterweight. Since then however he hasn't looked back scoring wins over Daishi Nagata, Ryusei Nakajima and Kazuyasu Okamoto all by stoppage last year. Those wins showed that Baez's power is legitimate, he's a brutally nasty power puncher, who swarms on opponents, and lets his shots fly. He might not be the most technically impressive but he is a strong, powerful, heavy handed and energetic monster at this level.
Aged 34 Baez is no spring chicken, but his 29 career bouts have averaged just 4 rounds a bout. They have been mostly short with his power being the key. He's not avoided damage all together but is a relatively young 34 year old and someone who can clearly have a few more years on the Japanese domestic scene. That's not to suggest he's the best in the country at 140lbs, but there's very few fighters in Japan who would be favoured over him, perhaps only Hiroki Okada and Koki Inoue.
Given his edge in power, aggression and sheer brutal physicality it's hard to bet against Baez here. We know Hosokawa is tough but unfortunately we suspect that will be his downfall. He will be there to fight against Baez but will take a lot of heavy shots, and we suspect he will be worn out in the middle to late rounds, as Beaz claims his biggest career and becomes a national champion in a second division.
