Kooch knocks in for a par three, exiting stage left for Spieth to steal the show. To the untrained eye, his birdie putt looks like it has a chance. To the world number three's sniper-like trained eye it is nowhere near. He marches after the ball as it drifts left.

Jordan Spieth is making this golf lark look easy. Another knock from tee to green on the par three 12th leaves him within striking distance.

Matt Kuchar tries to follow suit but is a club short. A monster of a birdie putt tries its best to get to the hole, his caddy trying to direct the ball with his flag like traffic controller.

The sun is not shining on Ian Poulter right now as he goes bogey-bogey. The par-three 12th sees him scrambling and the six-foot putt he has left is too much.

Rory McIlroy hits the green nicely off the tee on 14. Both men are looking over their shoulder at what might have been right now. Some dude from Texas is just taking it away from everyone.

I'm just off the 18th fairway and the view to the left and view to the right tell two very different tales!

Bubba Watson, you may have noticed, has lost a lot of weight. The before-after image on top shows it a little.

The two-time Masters winner has never really looked overweight but he says he's given up "everything that tastes good" in order to get in better shape.

"I’m eating small meals more times," he says. "I threw in fish for the first time, a lot of chicken. Normally I don’t like eating on the golf course, but we made these little protein balls.

"The stuff everybody loves? I just cut it out. So I’m basically just bitter at the world."

Bubba said the weight loss impacted upon his swing but from what we've seen this week, he's finding his groove again. So go get some chips to celebrate Bubba.

A lime green ball. Not seen one of them since 1994. Well, apart from yesterday when Bubba Watson played with one. There's more neon in Bubba's bag than a nu-rave club night. Two birdies in three holes lift the American up on the verge of the top 10.

Rory McIlroy is again close with a birdie attempt but there's nothing at 13 for him. His start today was exhilarating but the tank is running dry. It feels like he's chugging his way around now...

Matt Kuchar to putt for birdie, but there isn't enough on it and he rolls short.

Jordan Spieth now with the birdie attempt to extend his lead, it looks makeable but it bobbles a few inches past.

The leader rolls in for par, while Kuchar is also down in four.

PNeakte: My late gramp. Died in 2013. He got me into golf. I'd give anything for one more round with him.

BowlsTM: Me, Peter Schmeichel, John Hartson and Adrian Edmondson. My three heroes.

SMJ: Peter Alliss, Oscar Wilde & Billy Connolly.

Kuchar out of the rough finds the front of the green.

Spieth is 167 yards out, a whip of the club and he lands to the right of the hole

Ian Poulter made to pay like he's at the supermarket checkout on 11. No clubcard points will bail you out of trouble when you find the thick stuff off the tee here. His 35ft putt for par is always unlikely to drop and that grind for the birdie on 10 now seems a tad wasted.

Jordan Spieth on 11th and drops his drive into the fairway.

Matt Kuchar is next on the tee box and his drive lands just off the fairway, into the short cut rough.

Rory McIlroy has around 30ft for birdie on 12, lovely stroke through the ball and that's close but not enough. This has not been his day. On 11 Ian Poulter has found rough off the tee, Brooks Koepka is in the fairway and slings a ball onto the green with backspin galore.

Gary Woodland almost gets the first ace of the tournament on the par three 183 yards 12th.

His shot pitches in front of the hole and looks set to drop in the cup but just passes by.

Unlucky for the American, but he takes the birdie all the same.

Kuchar knocks up close, very close in fact, leaving him with a simple knock in. Two putts are needed by Spieth, leaving the Texan still two clear at the summit.

While Matt Kuchar goes off with his strimmer, Jordan Spieth's only concern is that he doesn't have a full view of the flag. The dogleg on the 10th is obstructing his sight.

That's not a major problem though, a bit too much spin on his approach is. He pitches just short of the flag, the ball's rewinding revolutions taking it just off the front.

Kuchar needs to tense every muscle in his forearms to hack this one out... excellent effort. He's just short of the green and in with a chance of saving par.

Yesterday Colin Montgomerie told BBC Radio 5 live his dream fourball would involve his mum and dad.

So what would yours be? Any person dead or alive. Muhammad Ali? Elton John? John Gregory? Send them in to #bbcgolf.

I have been told there is torrential rain in Liverpool and thunder and lightning there.

The clouds are coming towards us. The sky at the moment is one large bruise, it is black and blue. Bit by bit the storm is coming and what impact will that have?

Jordan Spieth shows Rory McIlroy exactly how to play the 10th.... by spanking his driver way over the bunkers lurking in the distance. Pretty easy really.

Matt Kuchar tries the same approach, but his ball is dragged off left again. Has someone got it on a lead?
