"Manny is quite severely marked up under the right eye, that's from the jab. They are getting a bit reckless, and I like that."

Floyd Mayweather Snr tells his son in the corner: "I don't know what the hell is wrong with you man."

A wake up call or genuine concern?

Pacquiao has to up the pace, he's being played by his opponent here.

He starts round six energetically, that's the stuff he needs but a clinch sees referee Kenny Bayless yell "keep it clean".

Back comes Pacquiao, he lets a few go with Mayweather again confident near the ropes. Three cross shots get the crowd roaring. They know he is up against it and has work to do. These punches don't look measured from Pac Man but they at least show willing and he will take that round. Again, not a lot in it but the increased intensity is working for him. Can he sustain it?

We are halfway, I'd say 4-2 Mayweather.

Don't forget, the Money Man has the reach advantage here. Pacquiao has to work to get into range and is finding it hard work.

"If I'm in Floyd Mayweather's corner now, I'm saying if Pacquiao keeps backing off, he'll get trapped in. I've got it 3-2 to Mayweather."

Floyd will know that last round was far from his own, what has he got in response?

You can feel the respect between the two. A chess match? I'll throw when you throw. Make your move.

A quiet opening minute to round five, forward comes Mayweather at speed, he thrusts himself onto Pacquiao with three shots but they barely landed. Shuffle, shuffle, Mayweather darts out of range, then a left jab and another, neither land. Pacquiao feints, will he throw? No. Lateral movement and Mayweather is out of range. Great boxing, technically brilliant from the showman. This will be his round. Nothing devastating, just too good.

"That was the best round of the contest so far for Manny Pacquiao. Mayweather was under pressure. How will he respond? On our scorecard now, it's two rounds apiece. It couldn't be closer."

The speed of Mayweather under attack is absolutely incredible. Even against the ropes he just ducks low so he can't be punched on the back of the head. It's a brave style, he puts himself in the firing line but has every confidence of getting out of it.

But hang on, what is happening here? Pac Man has his man backed up and sweating. Four shots, wallops too and the roars are deafening. This is more like it from the Filipino. His opponent had no choice but to get a guard up and take some punishment there. Hearts were racing, the world gasped. Pacquiao smiles on his way back to his corner. We have a fight!

"The crowd are willing Pacquiao on here. They are so partisan. If they could get in the ring with him they would."

Manny Pacquiao rolls his shoulder, he looks for an angle, can he get in? Not quite, he throws himself into range but can't get anywhere near this ballerina. Referee Kenny Bayless has to break the pair on the ropes. Is a tussle Pacquiao's only hope? Now he corners Mayweather but the head movement is blistering, allowing the WBA and WBC champ to avoid serious contact.

The feinting is good from Mayweather, when under fire he springs back out of range. Dance, dance, dance. Round over. A nice right hand from Mayweather ends it. Not much in the three minutes but the elusive nature of Money Man is standing out.

"Mayweather won it clearly and cleanly. What's worrying for Manny is to make sure he keeps his left hand up. He is going to get dropped"

There is almost a silence in the arena, such is the intrigue. Pacquiao is backing up his man to the ropes but the balance and defensive skill of Mayweather is as good as ever. In rushes Pacquiao, a big left body shot but it's well telegraphed by Money Man, he fields it. Mayweather is pawing him away and then bang, in dives the American sharply. A right hand and a stinger. He looks sharper early on, more aware, more alert and explosive.

Mayweather's round.

"That was Floyd Mayweather's round. It started to open up later on. The crowd are living and breathing every punch."

Cagey opening, feel your way in, a couple of jabs from Mayweather. Then he tries to go to the body.

In goes Pacquiao near the ropes but just as he realises he is in counter-punch territory he gets tagged, right hand, best shot of the early exchanges.

The orthodox-southpaw stances sees their feet clash once. That's how close these men are. Another jab from Mayweather gets nothing but glove. He is just about nicking this round and a counter right hand will definitely see him take the edge after three minutes. He tempted Pacquiao in and caught him sweetly. It didn't rock Pac Man but he felt it.
