Since their first meeting, which Ken Shiro won by majority decision, the champion has gone on to distinguish himself as a leading fighter at 108lbs thanks to wins over Pedro Guevara and Gilberto Pedroza. In those bouts he has shown clear improvements and looks to be a fighter who has grown since claiming the title. As for Lopez he has been he has been mostly inactive with his only bout between his loss to Ken shiro and this rematch being a win over unknown Mexican fighter Efren Bautista.
Aged 26 Ken Shiro is already a fighter who is showing signs of becoming a real star in Japan, that's despite the fact his first two world title fights were shown live in his homeland and the fact that fans had been following him from his debut. He was touted for big things when he turned professional following a solid amateur career, and was also given extra attention due to the fact his father Hisashi Teraji was a successful fighter claiming Japanese and OPBF honours. On his way through the ranks the youngster not only did what his father managed, winning the Japanese and OPBF Light Flyweight titles, but also claimed the WBC Youth title to become a triple crown winner after just 8 bouts.
In his 10th professional contest Ken Shiro would defeat Lopez for the WBC title in a coming of age performance. Prior to the bout he had shown the tools to be something special, showing he could adapt to his opponents, box, brawl and counter, but had never managed to put it all together as he did against Lopez. He not only showed he had the skills, but also the toughness to see out the final round when Lopez was really bringing the heat. His skills, and desire to win, were on show again when he narrowly defeat Guevara in what was another really tough bout. Against Pedroza however it seemed like Ken Shiro wanted to show the fans his boxing, which he did early on, before closing the show, which he did in impressive fashion in round 4. That win showed he could box or punch, and it's his ability to mix various styles that makes him such a fantastic young fighter. There are areas for him to build on, but with his speed, physical strength, ring IQ and under-rated power he could be a nightmare to dethrone in the coming years.
Whilst Ken Shiro is really just starting to capture the attention of the wider boxing fan base in Japan Lopez has been on the radar of fight fans for years. The 36 year old made his debut way back in 2003 and although he suffered some early career set backs, including a loss to the under-rated Juan Palacios and a loss to Adrian Hernandez, he would rebuild from a 13-4 record to become one of the key figures in the world title scene. Amazingly he wouldn't get a world title fight until 2015, when he was 33 with a record of 25-5 and despite a great effort he would lose a close but clear decision to Pedro Guevara. The following year he would get his second shot, and defeat Yu Kimura, who had beaten Guevara, for the WBC title. A title he would defend once, out pointing Jonathan Taconing, before losing the belt to Ken Shiro.
Despite his age Lopez is a fighter who hasn't shown anything in terms of ageing. He's a really smart fighter who uses his southpaw stance fantastically, moves around the ring intelligently and can box or brawl. His legs and boxing brain took him to a clear win over Kimura , despite the ridiculously poor scorecard of Juan Carlos Pelayo, and his win over Taconing showed just how good his ring craft is against a dangerous puncher. Sadly for him his work rate and out put isn't the best and he is perhaps due to lose some of his his movement. No one will doubt his boxing brain, but his reactions may well have slipped between the first bout with Ken Shiro and now.
At his best Lopez would be a real handful for any active 108lb fighter, and would give fits to many of those just below the divisional elite. At 36 however it's hard to know what he really has left and it's fair to say that Ken Shiro is just getting better and better. Although we don't see this as being an easy fight for the Japanese fighter we don't see Ken Shiro losing, instead we are expecting a clear, but tough, decision for Ken Shiro. A stoppage isn't totally out of the question for Ken Shiro, but it would be a bit of a surprise given that Lopez has only been stopped once in his 36 fight career.
Our prediction is a clear decision victory for the champion, who will put to bed any doubt between who is currently the better fighter and may also retire the Mexican, who has been a fantastic servant to boxing over the last few years. With a win we expect to see Ken Shiro begin the hunt for unification bouts, and could well find himself chasing any of the other champions.
