Shane Lowry's tee shot on the 11th goes a tad left and trickles into the light rough, but that should be fine on the par four.

Shane Lowry has been installed as the clear favourite to win the Open Championship, as he continues to impress during the second day.

The Irishman was 66-1 before the start of the tournament but is now into 4-1 favourite to win the major, currently joint-leader at -10.

Elsewhere, Brooks Koepka has dropped to joint-second favourite at 7-1, alongside Tommy Fleetwood, with Justin Rose on the periphery at 8-1.

Oddschecker spokesperson Callum Wilson:, external “Despite starting the tournament as a 66-1 outsider, Shane Lowry’s remarkable showing has rightly seen bookies cut his odds dramatically to claim victory at Royal Portrush."

David Duval had an absolute stinker yesterday, with a fourteen on the seventh.

He's not exactly loving life today, either. The American bogeyed the first and triple bogeyed the second. Ouch.

If you've just joined us, you've missed Shane Lowry being a total legend.

Sergio Garcia sees his long-range birdie putt on eight on rink around the edge and stay on terra firma.

The Spaniard remain on two under.

Oh. My. Word.

Shane Lowry can do no wrong.

He should definitely buy a lottery ticket tonight (not that he'd need it if he wins this).

The Irishman taps a birdie putt down the hill on the tenth green. The ball hesitates, then curls to the right and drops in the hole.

He has a two-shot lead and cannot wipe the smile of his face.

Rory McIlroy with a snaking downhill putt of about 30 feet to try and pick up an opening birdie...not quite.

He will have to settle for par.

Rory traipsed down the first waving and nodding to the masses of fans packed either side of the fairway. On a side note, his white club towel is already covered in mud and grass stains.

There’s a washing powder advertising deal in that somewhere...

A solid start to day two for defending champion Francesco Molinari as he lands his par putt on the first.

He probably needs to get down to +1 to make the cut.

Shane Lowry's birdie putt on the ninth stops a couple of centimetres to the right of the hole.

He taps in for par. Still in the lead.

There were a few nods of appreciation as the group before McIlroy played the first.

“Go on Frankie”. “Have a good round, Scotty”. “I knew it was DeChambeau because of his hat!”.

But the volume just cranked up several notches when Rory got to the tee. In front of one of the patrons’ clubhouses the hustling and excitement was reminiscent of punters rushing to the tote at Cheltenham or Aintree. It’s getting lively!

Rory McIlroy is given a hearty roar from the teeside gallery as the MC gives him a big build-up.

He steps up to his peg and lashes it down the middle.

Nothing wrong with that after he went out of the bounds on the same shot yesterday.

He has a hearty chuckle with his caddy as they shelter under a brolly. Nothing to lose today, no real pressure, let's just play and see what happens.

John McEnerney: The Burly Men at the top of the leaderboard. The gym goers getting blown around.

Remember 'pathetic fallacy' from GCSE English? Neither did I really, until I googled it again just now.

It is 'a literary term for the attribution of human emotion and conduct to things found in nature that are not human'.

Basically it is dismal and gloomy down in Portrush and Northern Ireland's flailing great home hope Rory McIlroy is on the first tee.

He is going to need an absolutely out-of-this-world round to have even a sniff of making the cut, currently projected at one over.

Realistically he is heading home.

If his golf career goes awry, Shane Lowry could be a bomb disposal expert or something - he is so cool under pressure.

His second shot on the par-four ninth lands on the left side of the green and this should be at least a par.

The sign next to the entrance at the first tee reads “full”, such is the clamour to get a place to watch Rory McIlroy tee off. The Northern Irishman may have struggled yesterday, but he’s still pretty much the most popular man in town.

Woods leaves himself a long putt for par and he can't quite make it.

The 15-time major winner finishes on a bogey and frowns as he tips his hat to the crowd.

At least the fans in Northern Ireland got a couple of days of him.

Tiger Woods looks at the ground as he's given a warm welcome onto the 18th green. For a while it looked like he might sneak into the weekend after a couple of birdies in a row, but that’s extremely unlikely now.

Jordan Spieth went on a bit of a run on his front nine, picking up five shots in four holes. Well worth a watch I reckon...

It was a disappointing day for defending champion Francesco Molinari on Thursday.

But there have been plenty of moves made already today, maybe the Italian can make his.

He's on the first tee now with Bryson DeChambeau and Adam Scott.
