Why all the low scores?

This incredible course, decorated with over 1,000 bunkers, is statistically getting easier to play.

The 7,500 yard monster of a course played at an average 74.14 strokes in round one but dropped to 72.9 strokes in the second round.

The hole where prayers, luck, skill and every ounce of effort is needed is 18. The par four is playing at an average 4.6 strokes and in my book, that's just cruel.

That wonderful effort from McIlroy moves him into a tie for seventh already. There's a very, very low score out there today. Let's be bold, I'll say we get another 63 to match the effort of Hiroshi Iwata yesterday.

WOW. Rory Mcilroy has no right to do this on five from off the green but his effort from the fringe moves at pace to one place and one place only, the cup. It needs a bit of help from the flag stick to take the pace off it and boy oh boy, what a move he's making.

Tiger Woods is a notable absentee from the weekend field, once again, after finishing four over par after two rounds - two shots outside the cut.

Woods has now failed to make the weekend at the US Open, Open Championship and US PGA this year, and admitted: "It's frustrating to miss any cuts, because any time you miss a cut, you don't have a chance to win the event."

However, the 39-year-old remains optimistic he can regain the form that has won his 14 majors.

"The confidence is growing quickly," he said. "That's the fun part. I'm hitting shots and able to hit shots that I haven't been able to hit in years and that's nice again."

Woods has announced he will play at the Wyndham Championship next week.

Brandt Snedeker treats us to the shot of the day so far from 84 yards out on the second hole. His ball spins behind the cup and leaves six inches for birdie, lovely control.

Steve Stricker seems to always bank these putts from 20 feet and does so as usual for a second birdie of the day on six. He's from this neck of the woods - Edgerton, Wisconsin to be precise - so the spectators love seeing his putt drop.

So who wins? Simple question...

Much like Phil Mickelson, Bubba Watson's game has threatened to burst into life this week but some well-placed bunker or piece of thick rough has seemed to do for him repeatedly.

No threat of such hazards here though as he clips a wedge into the ninth green. It checks a little on bounce one, a little more on bounce two and by bounce three spins to within three feet to set up birdie.

Rory McIlroy looks strong over the ball in his stance as he sizes up the long par-four fifth hole. He carries the dog leg with a boomer - great position.

Rory McIlroy strides with purpose off the fourth green and why not, he has birdie fuel running through him.

His putt briefly threatens not to take the break but obliges late on to drop below ground. If you'd offered him two birdies in four holes I think he'd have jumped at it, even with a sore ankle.

All pars for Luke Donald, a super putt on three saves his card from an ugly bogey. Phil Mickelson can roll in another birdie here on 14... just off line.

This 22-year-old has placed in the top 10 at seven of his 25 events this season and he gets talked up a great deal. At two under, can he launch an attack from way back?

It's a good start, birdie on one.

These ladies and gents were hiding in the media tent last night when the storm struck.

The BBC Radio 5 live Sports Extra commentary team are in place and will be live tonight at 20:00 BST.

You can listen to Iain Carter, Eilidh Barbour and Jay Townsend live through your computer, tablet or mobile by clicking the live coverage tab at the top of this page when the clock strikes eight.

Rory McIlroy you little beauty. He picks his ball up off the fairway so gracefully and the noise the contact makes is superb, as is the result. Around six feet for birdie remain. Bubba Watson... fancy a run from him? He picks up birdie on eight and makes it to two under.

Watson has driven the ball a whopping 317 yards on average this week. He has the power but does he have the accuracy to really build momentum?

I don't want to put the curse on him but could Phil Mickelson be in with a shout of a 63 today? His eighth birdie of the day arrives as he uses that trusty putter to curl into the cup on 13. A good stroke from 10 feet and Lefty is five under overall.

Rory McIlroy on the third, flanked by Lake Michigan to his left and mounds you don't want to dice with to the right. Don't push it, don't pull it, keep it straight... and he does.

Into the heart of the green and a birdie chance of around 20 feet. He stands over this ball and gives it some pace... gutsy... wide.

Henrik Stenson carded a great round of 66 yesterday and reaches three under with a lovely putt on two - tonnes of break in that one.

Germany's Martin Kaymer gets underway at 19:27 BST at four under and tells Sky Sports: "If I shoot one more low round today or tomorrow I think I may still have a chance. It's all about the putting. I haven't made any putts over 15 or 18 feet. I think If I can make a couple over the next couple of days I might sneak up there.

"I really do hope they make the course a bit firmer. I think you need to shoot 16 or 17 under par to win here and I think that's a very low score for a major championship."

It's probably not enough to say he's making a move of substance yet but Rory McIlroy is at least up and running - birdie on the second.

He took a straight line up the par five with his drive, his lay up, and a chip down the line of the flag. Dead aim all the way and the putt followed suit.

Jason Day may well have ended Friday night as a co-leader and found himself two back by Saturday lunchtime but he's in upbeat mood.

Day has a remarkable nine top-10 finishes in major championships and two of those arrived this year. So is this his time? As he says on Twitter,, external his target as things stand is a fellow Australian - Matt Jones.

Just how did something so beautiful turn so volatile last night?

This course is just 17 years old yet looks like it has been carved into the banks of Lake Michigan forever.

Our leaders are scheduled to tee it up at 21:03 BST, so get some snacks in - maybe the odd energy drink - and tweet us your views on #bbcgolf.

Phil Mickelson, stunning chip on 11, a foot left... birdie. Louis Oosthuizen has a snaking putt on five and makes birdie. A raise of the right hand is as pumped as Oosthuizen gets.

Victor Dubuisson is another cool customer and barely raises an eyebrow as he cracks an iron from range to within a foot on 15. Tap in birdie - six under for the day, four under overall. Some round forming here for the 2014 Ryder Cup winner.

In the event you missed it, Tiger Woods could not evade the cut line as his second round ended earlier.

A mark of four over was two shots shy of the score needed to stay for the weekend.

Woods therefore has missed three cuts from four majors this year. He'll be 40 when he tees it up at the Masters next year. Are his hopes of a 15th major over?
