Last weekend was another busy weekend for boxing as big events took place in the United States, United Kingdom, Japan and Australia.

On Saturday night, Fabio Wardley proved himself to be one of the most dangerous heavyweights in the world as he KO'd Justis Huni with one punch in the 10th round despite losing the majority of the fight at Portman Road.

Keyshawn Davis lost his WBO lightweight on the scales after missing weight by 4.3 pounds, leaving Abdullah Mason to step up and fill the main event slot in Norfolk, Virginia, where he won by TKO5 against veteran gatekeeper Jeremia Nakathila.

On Sunday in Tokyo, Junto Nakatani further-solidified his position as a pound-for-pound star as he won the vacant Ring bantamweight title with a bruising 6th-round stoppage win over Ryosuke Nishida. He also unified the WBC and IBF belts at 118 pounds.

Down Under, Ring cruiserweight titleholder Jai Opetaia maintained his undefeated record with a 5th-round knockout victory against overmatched Italian Claudio Squeo at Queensland's Gold Coast Exhibition Centre.

Tom Gray: It was a great win by Nakatani, but I've seen him box far better than that. Early on, he was rushing his work, overreaching on the left hand, and was made to pay on the counter by Nishida. It wasn't as polished a showing as what we've seen from him in the past. Don't get me wrong, I believe he intentionally came out for a firefight, took risks, and still won almost everything. Regardless, I can't endorse moving Junto above Bam at this point. I'm a huge fan of both guys, but Bam has a better resume, which is as clear as day, and his performance level and accomplishments are every bit as good.

Diego Morilla: I like Nakatani over Bam, yes. I am a fan of Nakatani and I have doubted Bam in the past. Cafu is going to be a solid challenge for Bam to claim his position back.

Anson Wainwright: I stick with Junto going over Bam. He blew away Cuellar (who I had high hopes for) and although he got hit a little more than usual, he took out Nishida in six rounds. I thought this would go further. I'd move him up and let's see if Bam impresses and can jump back over him next month. That way at least he gets movement for that impressive win.

Yuriko Miyata Nishiwaki: I think a fighter, especially with a title, who misses making weight is not worthy of being rated anywhere.

Dougie Fischer: I'm in agreement with dropping Davis now. He's never fighting at 135 pounds again, and we won't see him in the ring for months. It'd be weird seeing him ranked No. 2 at lightweight after he lost his WBO belt on the scales.
