There may be some technical flaws in Agyarko's game - he can look sloppy at times and loads up his punches - but he is landing the heavier hits.

Agyarko has grown in confidence round by round. He's moving around the ring more freely and throwing in quick succession with those fast hands.

The Belfast fighter is crouched down and then lunges in with two solid rights. Single punches which Rubio should see coming, but doesn't. The Mexican looks to be tiring.

I'll echo Michael's sentiments, so nice to see David Diamante back to full health. Brilliant MC. Top bloke. Great hair.

Great to see popular ring announcer David Diamante back in an English boxing ring for the first time since a horrific motorbike accident in December nearly left him paralysed.

He returned to the ring last week in San Diego for the first time for the Roman ‘Chocolatito’ Gonzalez v Julio Cesar Martinez super-flyweight contest, which Gonzalez won, but this is his first English show since the thriller between Joseph Parker and Derek Chisora in December.

After the accident, 50-year-old American Diamante said he had been told by doctors that the bone which penetrated his spine left him just two millimetres from being paralysed.

Juan Carlos Rubio is all smiles as he walks to the ring in a sombrero, accompanied by some traditional Mexican music. He has a record of 18 wins and one defeat.

This is a real step up for Caoimhin Agyarko, who confidently struts to the ring and fist bumps MC David Diamante.

Belfast's Caoimhin Agyarko is a prospect who says 2022 will be his "breakout year."

The 25-year-old has won all 10 professional bouts and defends his WBA International Middleweight title against Mexico's Juan Carlos Rubio.

Speaking to BBC Sport earlier this week, he said: "I've got a target on my back now," he said.

"There are going to be a lot of middleweights who will want to take this title away from me. But in terms of my mindset, it changes nothing for me.

"This is just a step towards being the first black Irish world champion. It's just more motivation to train harder because I want more titles, I want them all."
