Martin Warren: 7-4 to Rocket Ronnie.. I have a feeling this Masters final will be over by 10pm with the way this is going.

A.YELLOW: I'm sure O'Sullivan will be fine, but watching him making mistakes, makes me feel uneasy. 

Julian Pollard: The first session killed Joe Perry. He let Ronnie of the hook and back into the match.

The chances are coming for Perry, but he is not taking advantage of them. He has 15 points to his name when he tries to pot this red...

...but undercooks it to leave himself with no shot on the black. 15-0.

If Joe doesn't win the next frame I think it's curtains for him.

Ronnie's shot selection has been bang on all week. He's been waiting for his chances and he seems to be really happy to be out there competing.

O'Sullivan was unable to capitalise on this pot, although he still went on to win this frame.

You have to take the chances. And this is one that has slipped through Joe Perry's fingers. He only gets 12 points on the board and this black stays out.

He is not too impressed and is showing signs of his frustration. And this is another frame that has gone. Seven for O'Sullivan, Perry in dire, dire trouble.

And that is a bad miss. O'Sullivan, looking like he has frame 11 in a tight headlock, storms through with a break of 47, and a lead of 55. But this below shot stays out.

A lot of work for Perry to do (he is 0-55 behind) in the 11th, but a chance nevertheless.

Little Frank: Absolutely remarkable that one missed red to make it 5-1 has completely derailed Perry's game.

Kirsten: Oh this is looking ominous for Joe Perry now, Ronnie is in full swing. Unplayable when he's in the mood. A genius.

So this is a test for Joe Perry now. He is in the biggest match of his career and has just lost five frames in a row.

A loose safety gifts O'Sullivan a chance in the early stages of the frame, but the six-time champion only pots a red and a black before going safe. 0-8.

It's not been the best snooker and it's not vintage Ronnie O'Sullivan but he is buzzing around the table now and starting to play some amazing shots.

There are ominous signs for Joe Perry now. He needs to win one of the two frames before the interval.

Ronnie is just starting to take control and Joe is starting to feel the pressure. It's a big day, his first final in a major and he was in with a great chance when he led 4-1. Joe needs to win one of the next two frames to keep himself in the match.

Alex Haworth: What is it about the shout happy audiences at the Masters this week?

Vinnie Shaw: Finally, the referee berated the crowd for their constant shouting.

The first frame of the evening took more than half an hour, but the next is much more fluid.

In just over six minutes, O'Sullivan makes a break of 68. Perry comes to the table needing one snooker, but it is to no avail and O'Sullivan moves two clear with another decent break - this time a 56.

That is five frames in a row for him now and the foot is firmly on the accelerator pedal. Is there any way back for Perry or will O'Sullivan storm to the title from here?

"You're not helping the players when you shout out," warns referee Paul Collier, to those fans in the crowd that have decided to scream 'Come on, Ronnie' every time he comes to the table.

We're into frame 10, with O'Sullivan 29-4 up, and his fans happy - even those that have just been told off.

Nick Comber: Ronnie looks very, very focused. 20 years ago he didn't have the patience to win tactical frames like that.

Mark Hollingsworth: If the rest of this finals frames are going to be like that, I'm going to be exhausted at work tomorrow. 

Moke: Perry has to make more of his chances when in.  

This is the shot that wins O'Sullivan the frame, a very tidy red into the middle.

Remember, Perry had a 4-1 lead and had chances for a 5-1 lead. Now, he has lost four frames on the spin and trails for the first time in the final.

Loving the effort, top work. The green ball might be a bit tricky to see though.

Mark Lewis: I can't be only person watching the snooker thinking that's what the scores/table looked like when I played.

O'Sullivan gets a chance when an attempted red to the middle pocket from Perry stays out.

He can't make too much of a dent on the scores, but gets another chance when a loose Perry safety is a bit wild.

This is the situation shortly after, in the midst of a safety battle, as we are heading for what is comfortably the longest frame of the match so far.

Tight. Tense. Nervy.

We haven't seen many points scored so far, but this has probably been the best shot we've seen in the evening's play.

Claire Nellany: Having to follow the text stream as on a train but still excited to see how this turns out. 

Don't worry, Claire. We'll keep you updated.
