Ryder Cup skipper Darren Clarke eagles 18! Lovely stuff, he's back to +3. What news of Clarke's old mucker Lee Westwood? He kicked off with a birdie and has made five pars since to be -2 and five off the lead. 

The battle of the flat sticks ends up all square. Jason Day gets a decent read off Rory McIlroy's putt; the weight is almost perfect as the ball curls towards the cup but it finishes an inch behind.

Rory in for par. A trembler from four feet after a slow putt up the hill.

Phil Mickelson also knocks in after his initial birdie putt failed to go close.

Here's our leader, on tee at 18, and Grillo can get on in two from there. Sullivan with another birdie chance at four... in it goes again, the man from Nuneaton has got his putting boots on and he is two off the pace on five under.

Phil Mickelson finds the green from the middle of the fifth fairway but his ball dribbles away from the pin.

Rory McIlroy is next up from 10 yards closer in but he is instantly shaking his head and looking away in disgust. For most of us, that would be a satisfactory ending but McIlroy is chasing birdies and he won't make too many from 40 feet away.

Jason Day is the final one to have a pop, he is firing from 140 yards, a couple of yards closer than Rory but he too comes up short.

Eight-foot birdie from Sullivan at three, the Englishman moves to four under. Great saver by Grillo at 17, he stays one clear at the top of the leaderboard. Billy Hurley, a winner on the PGA Tour this year, splashes in at 15 to get to two under, he's opened up with four birdies. Hurley, I'm told, is a former US Marine. 

First birdie of the day for Rory McIlroy on the fourth, rolling in from 14ft.

He needs a few more, but it's a start.

Phil Mickelson with an uphill putt for birdie. He gives it a whack, a bit too much on it and it rolls past. Par for the American and the same result for Jason Day.

Andy Sullivan out of the rough at the third and that's a beauty, makeable birdie chance. Leader Grillo parred the 16th, his seventh, but he's tugged his ball left of the green at 17 after an errant tee shot.

No birdie yet for Rory McIlroy, he needs to start making a move,

As it stands, with the projected cut at +2, some pretty handy players will be missing the weekend, including McIlroy, Garcia, Mickelson and Dustin Johnson, although Mickelson is fighting back after that triple at the first, making birdie at three to get to +3.

Jason Day drops on the third, he three putts for a bogey.

It has taken three holes and he started with a triple bogey, but Phil Mickelson is now back on track.

He birdies the third, a 25ft putt to go to three over.

Rory McIlroy with a 315 yard drive on the third into the middle of the fairway. He takes his seven iron and finds the green to leave a 20ft putt.

Birdie opportunity awaits, one that he needs to take.

Welshman Jamie Donaldson birdies the third to get to three under, it's looking like scoring is possible out there today. England's Ross Fisher, who carded a 66 yesterday, is off the mark with a par today. Brooks Koepka is on the verge of the American Ryder Cup team and he's moved to -3 with a birdie at the fourth.

Jimmy Walker birdies the fifth and is only one behind leader Grillo. Walker had five wins on the PGA Tour between October 2013 and March 2015 but hasn't had a win this year. He also missed the cut at the US Open and Open Championship.

Germay's Stephan Jaeger shot a 12-under-par 58 on the PGA Tour's secondary Web.com Tour to record the lowest score ever on either of the main US-based circuits.  

So in honour of Jaeger's achievement, we want to hear about your greatest ever rounds and we want proof if you have it.

We have a new leader as Argentina's Emiliano Grillo drains a 40-footer at the 15th to move to seven under. The 23 year old won a tournament in his rookie season on the PGA Tour last year and finished tied for 12th at this year's Open.

Hideki Matsuyama moves to four under after birdie at the par-four sixth. What a great saver that is from England's Andy Sullivan at the first, he stays three under. As it stands, only two of the 20 club pros are inside the cut, and they're yet to go out. Only one club pro has played the weekend in the last two years.

Defending champion Jason Day takes a birdie at the second and he goes to three under.

No such luck for Rory McIlroy, he misreads his birde putt but picks up a par.

Time for Phil Mickelson to put that first hole behind him with a seven foot putt for birdie.

He also misreads it and settles for par.

McIlroy and Mickelson not making the cut as it stands.

You know that par putt of Paul Casey's on the third. Well, he only went and missed it. It was no more than three feet and looked pretty straight but he tugged it and it span round the hole. A bogey and back to one under.

Jimmy Walker safely in for a two-putt par on four to stay five under.

Emiliano Grillo is going about his second round in fine fashion. A 12-foot birdie putt on the par-four 14th, his fifth hole, lifts him to six under par and a share of the lead with Henrik Stenson, who is, of course, safely in the clubhouse.
