For Watanabe this is a chance to add to his excellent career which has seen him claim Japanese and OPBF titles at Welterweight and a PABA title at Light Welterweight. It's also a chance to prove, at the age of 33, that the old dog still has plenty up his sleeve, despite recent losses to Magomed Kurbanov, Takeshi Inoue and Toshio Arikawa.
For Maruki on the other hand the bout is a third shot a Japanese belt at 154lbs, having come up short in close bouts to Shindo and Yuki Nonaka. Sadly for Maruki he has got a reputation as a nearly man having also lost in the 2012 Rookie of the Year final, losing to Ryota Itoyama, and needing two cracks to win the WBC Youth Light Middleweight title.
Watanabe has had a thrilling career. He would win his debut by decision before going on an incredible “stop or be stopped” run, that saw him going 17-3 (17). All 3 of those losses came in the first 3 rounds, including a 90 second loss to Tadashi Yuba in a Japanese Welterweight title fight, whilst 9 wins came in the opening round and all 17 in the first 8 rounds. Since then he has developed more than just his power, and has climbed a number of good wins, both by stoppage and by decision. Those have included a huge 2011 win over Yo Inoue for the Japanese and OPBF Welterweight titles, as well victories over Koshinmaru Saito, Prawet Singwancha and Kyung Suk Kwak .
Watanabe had gone from 18-3 (17) to 33-4 (28) before losing in a Japanese title eliminator to Toshio Arikawa. That started a bit of a rot for Watanabe though a win this past April over Ratchasi Sithsaithong showed there was still some hunger there for Watanabe who will be wanting to make the most of this opportunity.
Maruki's career has been explosive and exciting than Watanabe's but has been an interesting one with the 27 year old showing a lot of promise but just unable to get over the line when he needs to. He made his debut in 2010 and reached the Rookie of the Year final in 2012 before losing a close decision. He would suffer his second and third defeats in 2014, both of which were razor thin decisions. He would then lose Yuki Nonaka in 2016 and Shindo earlier this year, both in shots for the Japanese title.
Despite losing his biggest bouts Maruki is an absolute handful. He's tough, strong, heavy handed and aggressive. His issues has often been pacing and tempo, starting too slowly and needing to do too much too late, and struggling to set the distance of the bout, with his best opponents often keeping him at range and preventing him from using his body shots up close. If he can set the pace early, get inside and work away he can cross the line and get the big, much needed career wins.
We're expecting this, due to the styles of the two men, to be something very special. We're expecting both men to look for a fight, and throw power shots on the inside, there won't be a huge amount of feinting or technically impressive skills on show, but there will be a toe-to-toe war. For Maruki we think will be ideal, he's younger, naturally bigger and hungrier. Watanabe's power could be the difference, but we're thinking that Maruki will get it right, at least, and he'll finally pick up the big win.
