Right now the Bantamweight division is all but dominated by Japanese fighters. Three of them hold world titles and several of them are highly ranked challengers. Of them all however it's hard to argue with Shinsuke Yamanaka (20-0-2, 15), the WBC champion, being the best. Not Just the best of the Japanese Bantamweights but of Bantamweights worldwide.
Earlier today Yamanaka showed why he is so highly regarded as he became the first man to stop Alberto Guevara (18-2, 6) in what turned out to be a highly impressive result.
Despite taking the victory in the end Yamanaka didn't look like the divisional kingpin early in the fight. In fact for the first 4 rounds it was Guevara who looked like the special fighter using his movement and speed to almost confuse Yamanaka at times. Unfortunately for Guevara his work wasn't really rewarded by the judges who had him behind after the first 4 rounds, rather harshly.
Following the slow start by the Japanese fighter things started to turn around with Yamanaka claiming his first round in the fifth. From then on the bout swung from being competitive to being one sided as Yamanaka started to land his potent left hand.
In round 8 Guevara was forced to feel the power of Yamanaka in a bad way as he was dropped twice. By then Guevara's elusiveness had left him and he was becoming little more than a sitting duck for the power of the champion. Fortunately for the challenger he wasn't forced to take too much more as a knockdown in round 9 saw Guevara taking the 10 count.
