After getting himself 14 feet for par, Justin Rose is off line with his putt and leaves three feet for bogey.

Intake of breath as the usual dead-eye putter lets him down and it slides by.

A brutal double bogey for Rose.

I said earlier that Ludvig Aberg had underhit a putt at the fifth. Viktor Hovland has done the same and left himself a niggly couple of feet for par.

It's OK, he's tidied up to stay well in front.

As for Hideki Matsuyama, he's done very well to save after another wayward tee shot.

But what of Justin Rose...?

We've not mentioned France's Adrien Saddier but he is quietly mounting a challenge.

Four birdies and a bogey in his opening seven holes has him just three shots back from Viktor Hovland and in third.

Oh Rosey, he's beyond the path at the fifth and chipping from next to the tee box of the sixth.

The crowd parts and he takes aim. High, splash down and give himself a chance of a par.

He's done it very well and will have 14 feet to save a par,

What a putt from Ewen Ferguson at the sixth.

Shoved out on the fringe from 60 feet, he's judged that immaculately and round it comes before plopping into the hole.

A belter from the Scotsman!

Angry reaction from Justin Rose as he completely skews his tee shot at the par-three fifth.

Some rare colourful language from the Englishman as he contemplates chipping onto the green from the path.

Ah, hit it Ludvig!

It's a lengthy putt for the Swede so a two-putt par is just fine. Still he had the line and it just came up short.

Much better news for Justin Rose as he cleans up for his first birdie of the day. He joins Hideki Matsuyama at 10 under.

The leader is stretching away though. Viktor Hovland's third birdie of the opening four holes sees him take a two-shot lead.

Ugly for Hideki Matsuyama at the fourth. After scraping himself to limit the damage to bogey, he misses from four feet and it's the first double here today.

Away he drops from the lead.

Justin Rose is just behind the fourth green with his third shot on this hole, chipping out of the rough to set up a birdie chance.

Beautifully judged and he should be able to tidy up.

I'd imagine Viktor Hovland will also get himself a shot - terrifically played out of the sand from the Norwegian.

Plenty of people helping Hideki Matsuyama forage in the undergrowth for his ball down the left side of the fourth fairway.

He gets three minutes to find it and it looks like the search has been abandoned.

A hole that has been the easiest on the course today is going to pass him by - and could be costly.

Speaking of eagle opportunities, one here for Ludvig Aberg would see him join Viktor Hovland at the top.

Five feet and he's missed it. As emotional a look as Ludvig ever gives follows (the slight downturn of the mouth) and then a tap-in birdie.

It moves him one off the lead.

Hello, here comes another Brit up to 10 under par - and it's a Scotsman getting an eagle at the fourth!

As Ewen Ferguson did about 10 minutes ago, Richie Ramsay has tickled his putt in to pick up two shots - and join Aaron Rai three off the lead.

As one Englishman slips away from -10, another is making his own move.

A birdie for Aaron Rai moves him up to fourth, three back off the lead.

Remember when I told you the third was a tricky hole?

Not for Viktor Hovland. He's grabbed the lead outright with an excellent 14-foot birdie putt.

Big move from the Norwegian today.

More frustration for Justin Rose though as he gifts another shot back.

Weather update for you after that dark cloud opened up its wares about half an hour ago.

Wentworth is now bathed in sunshine.

Welcome to England.

It's not been a fun start for Ewen Ferguson, dropping three shots over his first three holes, but that should cheer him up.

A fine eagle at the fourth gets his scorecard moving in the right direction.

The difficult third has had its way with Ludvig Aberg and he's trudging off the green after making bogey and dropping out of the lead.

Must have known I'd put him in the headline and image on this live.

So now I'll have to go and change that.

Loud cheers reverberate around the 13th green as Rory McIlroy goes back-to-back on the birdie train.

That's three shots picked up in four holes for last week's Irish Open champ, and the crowd loved it.

A chance for a good finish too.
