The Japanese youngster turned professional back in November 2013, aged 18, and had a lot of expectations on his shoulders, with his team talking about him as someone with the ability to race through the ranks. It turned out his team weren't all talk, and in just his 4th fight he took on the then 18-0 Ryuji Hara, stopping Hara for the OPBF Minimumweight title. Just a fight later he won the WBO Minimumweight title, setting a Japanese record and after one defense he jumped up in weight. After just 37 months as a professional Tanaka won his second world title, claiming the WBO Light Flyweight title.
In the ring Tanaka is a lighting quick fighter. His feet are incredibly quick and his hands are even quicker. It's those quick hands that allow him to throw some of the sweetest looking combinations in the sport and allows him to get his shots off before opponents can react. He can control the range with either his feet or hands and when he's on song he looks like a very special fighter.
At his best Tanaka is one of the best offensive fighters in the sport. Sadly what he lacks is a consistent defense and that was notable seen against both Hara and against Vic Saludar, in Tanaka's only world title defense. He was dropped, and bullied, by Saludar in what was the worst performance of his career so far. Although Tanaka was poor against Saludar he did seem to put that, at least partly, down to making weight and the move has seen him look much, much better with some added power as well as a more durable look.
Whilst the champion will be in his 4th world title bout the challenger will be in his first, and will be looking to continue his impressive stoppage run. That run began in November 2012, when the then then 22 year old Acosta stopped Alexis Diaz in 3 rounds, and has continued through to now, with the latest stoppage being a 10th round TKO over Japhet Uutoni in a world title eliminator.
Acosta has scored wins in Puerto Rico, Dominican Republic and the USA. During those wins he has rarely gone more than 6 rounds and has faced mostly questionable opposition. Despite the poor competition Acosta has claimed the WBC FECARBOX and WBO Latino Light Flyweight titles. The most notable of his wins have been over Victor Ruiz, Juan Guzman, Luis Ceja and the aforementioned Uutoni.
Acosta is an out-and-out fighter with an aggressive mentality, despite that he can box on the back foot and has been seen landing some sensational counter shots, with his counter left hook looking particularly potent. He also seems to have nice speed, a wonderful variety of shots and they all seem to have nasty spite on them. It should be noted however that Acosta does look defensively open, and it looks like he makes a number of flaws, with his chin often in the air and he often leans straight backwards.
On paper this is a boxer against a puncher, but the reality is that both men are more than that. Tanaka is boxer-puncher, who can brawl when he needs to and has such incredible speed that his combinations are just a thing of beauty. Acosta is a puncher, but can also brawl, and has more than enough nous to his boxing to be able to box with good fighters. With that in mind this really is an intriguing match up, and one that could go either way. When put under pressure Tanaka looked comfortable, and Acosta will look to force himself on he Japanese fighter. Despite that we think Tanaka's speed will be the difference and he will counter, out manoeuvrer and out land Acosta, who will have real highlight moments, but not quite enough to wear down the Japanese youngster, who will do enough to take a very competitive decision.
