Westwood -3 (11*)
A good approach from Lee Westwood and more importantly a superb putt brings him back to three under on the second.
The Englishman made five birdies on the front nine on Thursday. He'd snap your hand off for that right now.
BBC Radio 5 Live
Some final words from The Great White shark Greg Norman, three times runner up here at Augusta, on BBC Radio 5 live.
'DJ and Rahm. I think Rahm is going to be a really tough person to beat around the golf course the way the conditions are'.

E Day (9*)
Casey -6 (10)
That'll be the first dropped shot of the day for overnight leader Paul Casey after his miscue at 10.
The Englishman had made a par start through the front nine but a bogey after the turn pegs him back to six under, three off the lead.
Koepka -5 (F)
What does Brooks Koepka do when he's finished his round. Work out, of course.
"I need to clean it up for the weekend if I want to win. No three-putts," he said. "I feel fine, I am glad to be done, go put my feet up, go work out - not that excited as I have got legs today, it's going to be a long day.
"My body feels great, just need to clean up those sloppy mistakes."
Rahm -7, DeChambeau +2, Oosthuizen -7 (11)
Drop. Drop. Drop. That's not far off from a birdie for Bryson DeChambeau on 11.
But no cigar. He'll have to be content with a par.
Jon Rahm's birdie putt doesn't have the legs, pulling up short while Louis Oosthuizen has a trickier read from left to right.
Three pars.
Woods -4, Lowry E, Ogletree +2 (9)
No patrons on site, but enough members and other personnel following Tiger Woods around that the defending champion is greeted with a smattering of applause on the ninth green.
He's in for par. Level par through the front nine today and four under overall.
More words from Greg Norman, who has been on BBC Radio 5 live.
'I'd love to mentor Dustin as I think he's only used 65% of his talent to date. I think he's the most talented player out there and he is the most athletic specimen in golf. DJ should dominate golf for years to come.'
Casey -7 (9)
Oooo... that wasn't the shot Paul Casey was after. Caught in the longer turf down a bank to the left of the 10th green, he clips beyond the flag and doesn't get the backspin he was after.
Instead it threatens to trickle off the other side, stopping in the fringes.
Rose -7 (F)
More from Justin Rose: "There were too many fives once we got going again. It got a bit tricky once we restarted. The wind kicked up. The 12th wasn't the solid wedge like it was on Thursday.
"Normally walking from the 11th green to the 12th, your heart rate elevates anyway because it is a bit of a climb. Your heart is beating maybe 20-30 beats a minute more.
"The patrons bring an energy that adds to that. The hole is never simple and it always gets your attention."
Casey -7 (9)
Right down the heart of the fairway from Paul Casey at 10 but the Englishman isn't impressed with his approach, dropping a shoulder in frustration after dragging it left of the green. Let's see how that lies...
Woods -4, Lowry E, Ogletree +2 (8)
Tiger bounces back at the first time of asking.
Woods bogeyed the last, but clips on from just in front of the green to within four feet and can trickle a birdie putt in from there. Back to four under, five off the lead.
Rahm -7, DeChambeau +2, Oosthuizen -7 (10)
Beautiful recovery from Jon Rahm but what's that from DeChambeau.
Short of the green he connects all wrong with his pitch, sending it way past the pin.
Not sure even he can believe that one, even the way things have been going today.
Rahm takes four. DeChambeau a five. Ouch.
Rose -7 (F)
Here's Justin Rose, who finished second in 2015 and 2017: "Certainly when I played against Jordan Spieth in '15. I did a lot of good things, there were moments when the momentum went his way.
"The same with Sergio (Garcia), but I felt like I played good enough to win the tournament - I know I can win, I just don't have an arm in a jacket yet.
"I have played in that final group a couple of times and really enjoyed it. It's fun."
Rahm -7, DeChambeau +1, Oosthuizen -7 (9)
'No way' shouts Jon Rahm who is off-beam for the first time in a while on his way into the 10th. His ball is well right and comes to a stop just above the right-side bunker.
Bryson DeChambeau is up next but it doesn't look like he caught that at all.
By the looks of it, he could do with taking a leaf out of Sungjae Im's book and slowing everything down.

More from The Shark, Greg Norman, on BBC Radio 5 live.
'I think the ball is now travelling too far and I definitely think there is going to be a tipping point and I know the USGA and R&A are in discussions as to how to arrest this the best they can. The guys have taken advantage of the rules. But how do you wind the clock back?'
BBC Radio 5 Live
Greg Norman, who has finished second in The Masters three times, is on BBC Radio 5 live, talking about the Masters.
"I've never seen Augusta National play so easy. There's something like 50 players under par which is unheard of out there. The golf course is soft, it's playing really slow and the carry of the golf ball is really important.'
Woods -3, Lowry +1, Ogletree +2 (7)
You can see the evening starting to draw in at Augusta, but it's at this time of the day the autumnal colours start to come to life - what a spot.
Tiger Woods plays a bump and run down the eighth that stops just short of the dancefloor.
Westwood -2 (9*)
Blimey what has happened to Lee Westwood? Last time I looked he had a birdie putt on 18. But he somehow pushed it past on the left.
Frustration on the greens, isn't exactly a new issue for the former world number one.
Langer -3 (F)
At 63, Bernhard Langer has become the oldest player to make the cut at the Masters.
"Let's have a toast to that!" he said. "I have been fairly competitive on the Champions Tour and had some good finishes here in the past few years. I love this place, even though I am probably 100 yards behind some of the longest hitters out here
"I am very tired right now. My wife just called and asked if I was going to hit some balls on the range... I am gong to go in the fitness trailer and get some treatment, relax. My alarm went off at 4am this morning. It's been a long day."
