Shinsuke Yamanaka v Alberto Guevara

Whilst we have several world title fights on Saturday across the world it's also worth remembering that this weekend also has a world title fight on Sunday as the attention of the hardcore boxing world turns to Japan.

Although originally the Teiken promoted super-card at the Kokugikan in Tokyo was supposed to have two world title fights the pull out of Cuban Abril has left us with just one as the popular Shinsuke Yamanaka (19-0-2, 14) fights the teak tough Alberto Guevara (18-1, 6) in a defense of the WBC Bantamweight title.

Yamanaka has become one of Japan's most notable boxers of the last few years due to a series of high quality wins. Like Toshiaki Nishioka before him Yamanaka has become of the of the Japanese fighters who has been facing notable opponents that are known by international fans. Not only as Yamanaka beaten fellow Asian's such Malcolm Tunacao but also international opponents such as Vic Darchinyan, Tomas Rojas, Christian Esquivel and Jose Nieves.

The key to Yamanaka's success is his over-all skill. He can be made to struggle, as he did against Tunacao, Darchinyan and Esquivel, but he refuses to be beaten and when required to go to the well he does it. He combines this refusal to lose with genuine KO power, a tricky southpaw stance, solid boxing fundamentals and very impressive defense for a Japanese fighter.

Although generally happy to box and wait for an opportunity Yamanaka can steamroll opponents when he feels like it, as he did against Nieves. This poses three problems to opponents. Will Yamanaka box their head off, go to war with them in a brawl-as he did with compatriot Ryosuke Iwasa or will he just try to get them out of there as he did with Nieves?

American fans should be aware Guevara who gave the insanely talented Leo Santa Cruz one of his toughest bouts late last year. Against Santa Cruz we saw Guevara move excellently and give Santa Cruz real problems in pinning him down for 5 or 6 rounds. Although lacking genuine power Guevara has developed a style, like Miguel Vazquez, which makes him difficult to punch.

Talented as a counter puncher or as a stick-and-move pure boxer Guevara is a tough test for anyone. He's not the best pure boxer in the division, that's a title certainly held by Anselmo Moreno, but he's well inside the top 10 and he could actually be a better pure boxer than Yamanaka, unlike many of the champions recent opponents.

Although I expect Guevara to really test the Japanese fighter it's difficult to see the upset here. Guevara probably has the toughness to see out the final bell, but not take the decision in what is a very interesting contest.

Prediction-Yamanaka UD12

Leo Santa Cruz v Alberto Guevara

Exciting Mexican youngster Leo Santa Cruz (22-0-1, 13) looks to finish off an excellent year with his third, and likely final IBF Bantamweight title defense as he faces the unbeaten but untested Alberto Guevara (16-0, 6) live on CBS.

Santa Cruz is quickly becoming one of the new stars of Mexican boxing and appears to be one of the sports most fun to watch fighters regardless of nationality. In terms of his style he's a very tough but educated pressure fighter who brings not only an "in your face" attitude to the ring but also very under-rated boxing ability and a deceptively powerful punch which he uses to grind down opponents.

Although Santa Cruz's record doesn't show him to be a puncher he has developed a real mean streak with which he's been able to force numerous stoppages with in recent fights. In fact Santa Cruz has impressively stopped 11 of his last 12 bouts early with only teak tough South African Vusi Malinga seeing the final bell with others such as Eric Morel, Alejandro Hernandez and     Stephane Jamoye all being stopped in that run of 12 fights.

I'm expecting this to be the final time we see Santa Cruz at Bantamweight, a division he seems to be out growing and if he puts on an impressive showing it'll be great to see him mixing with some of the top guys at Super Bantamweight.

Whilst Santa Cruz is well known by boxing fans who have seen him becoming a bit of a star this year, it's fair to admit that Alberto Guevara is much more obscure. In fact it's worrying to discover that Guevara (at the time of writing) is unranked by the IBF and is ranked #47 by boxrec. Almost as interesting is that last time out Guervara apparently weighed in at a ridiculous 136lbs, and now needs to cut back down to 118.

Despite being unbeaten since he turned professional a little over 3 years ago Guevara is really, really untested having fought only 6 opponents with "winning records". Despite the level of his opponents it's fair to admit that Guevara has been stepping up in recent fights with arguably his best 3 wins coming in his last 3 bouts however they are all several levels below that of Santa Cruz.

In all honesty I can't see many fighters at 118lbs living with Santa Cruz's aggression, power and work rate. I think he'd be a nightmare for both Anselmo Moreno and Shinsuke Yamanaka (both fighters who I love) and in fact Santa Cruz could well be the division's #1 fighter as a result I can't Guevara upsetting him. I think Guevara will get ground down and quite early as well.

Prediction-Santa Cruz TKO5
