The pressure to make sure he won was clear the opening round as he boxed cautiously behind his jab, and moved, stopping the wild and aggressive Pedroza from landing. The visitor had clearly come to win but spent much of the round hitting the air as the champion put on a show case of movement. That same tactic worked in round 2, though during the round the champion began to find his range and landed several uppercuts to the body.
The success Ken Shiro had in round 2 grew in round 3 as he began to hold his feet, look comfortable in there and began to try and look for opportunities to counter. Although it wasn't quite a masterclass it was beginning to look like Ken Shiro was starting to think about way to shine and landed several eye catching combinations.
Early in round 4, which was delayed due to grease on Pedroza's face, Ken Shiro landed a perfect counter right hand. The shot rocked Pedroza and opened the door for the champion to let his hands fly, which he did when Pedroza was on the ropes. The challenger tried to survive, holding the champion, but he couldn't keep the champion off him. A follow up attack, punctuated by a body shot, sunk Pedroza's knees and the shots kept flying until Pedroza was ruled down. The challenger looked like he had had enough but continued, for a few moments as Ken Shiro again jumped on his man and dropped him. This time it was enough for the referee to stop the bout.
Although unlikely to be included in the 2017 Fighter of the Year conversation the Japanese fighter has scored two wins over consensus top 10 divisional rivals, in Lopez and Guevara, and topped it off with a stay busy win to end the year. It's been a break out year for the youngster who seems to be constantly developing and with today's win will have built his profile significantly at home. The performance will have helped as will his personality which showed through in his post fight interviews shown on Fuji TV. There is still developing to do, but he did what he needed to and will be moving in to 2018 as one of the leading fighters at 108lbs.
With his TV debut a real success the question now is whether or not Fuji will continue to show case the babyfaced champion. There is a lot of very interesting contests out there for him, including rematches with Lopez or Guevara, a bout with WBO champion Angel Acosta or bouts with domestic rivals like Tetsuya Hisada and Ryuji Hara. For Pedroza however it's back to the Latino scene where he will have to hone his skills if he's to come again at this level.
