To Bubba-proof a course, simply ban pink drivers.

Alan O'Sullivan:, external Augusta was Tiger-proofed after Tiger Woods demolished it in 97....maybe they need to Bubba-Proof it now

Steven Horner:, external You gotta love watching Bubba hit driver!

Rory McIlroy may well have shot a one under 71 on his third round, but the two-time major winner was not able to match the score of the man sent out to mark his card - Jeff Knox. The 48-year-old Augusta member shot a 70 off championship tees.

"He beat me," said McIlroy. "I guess that was the funny story. I thought he was going to be nice and three-putt the last and we would have a half, but he beat me by one.

"He obviously knows this place so well and gets it round. I don't think I've ever seen anyone putt the greens as well as he does around here. I was thinking of maybe getting him to read a few of my putts out there."

Eddie Wattenbach:, external ‏Can't see BW holding on. More likely a newbie but rooting for Westwood.

Bubba and the big pink on the third tee. Only 350 yards, so he can drive close to the green. Feet all over the place, even off the ground, as he swings. It's right of the green, on the slope, but there's a chance of an up-and-down for a three.

Augusta is as picture perfect as you could imagine. Cloudless skies above umpteen shades of green. Where there is water, the sunlight shimmers a reflection. Jonas Blixt, in contention, pars three to stay three under. John Senden will have tricky putt for par at the same hole.

-8 B Watson (US) after 2; -4 Spieth (US) 3; -3 Jimenez (Spa), Furyk (US) 4, Bjorn (Den) 2, Blixt (Swe) 2, Senden (US) 1.

Selected others: -2: Scott (Aus) 3; -1 Rose (Eng) 13, Westwood (Eng) 8; E Poulter (Eng) 15; +1 Gallacher (Sco) 6; +2 Donaldson (Wal) 6; +3 McIlroy (NI); +5 Clarke (NI); +8 Lyle (Sco).

Rickie Fowler, with what looks like a pretty sharp haircut under a huge white cap, continues his charge by birdieing the 16th. He's down to three under.

Par four, 350 yards

Short, but treacherous. Bunkers on the left of the fairway lead to most players using an iron off the tee. The small, sloping green is not entirely visible from the approach.

Six feet out. Putter looking like a toothpick next to those lanky legs. Just creeping in the left side of the hole. Bubba gets his dropped shot back and then one. He's eight under, four ahead of the rest. On to the third.

Senden gets a shot back with birdie at the second, back to four under. Now Bubba for eagle...

"Donaldson, Bjorn and Blixt. How hard are these guys going to be on themselves if things start to unravel? Watch the mindset, see if the jaw drops."

John Senden, the Australian playing in the final group alongside Watson, bogeyed the first to slip back to three under. American Rickie Fowler has birdied the 15th to move to two under, whilst Justin Rose has drained a 30ft wibbly wobbly putt on 13 for eagle. The US Open champion is one under.

"Denmark and Sweden aren't two countries known for their golfing prowess. They're more known for skiing or whatever else they do."

Thomas Bjorn, playing in the penultimate group misses a birdie putt on the second. Jordan Spieth picks up a shot at the third to move second outright on four under. What can Bubba do after that bogey at the first? On the fairway at the par-five second. A swing of the purple-shirted arms...it's simply wonderful. Chance of eagle.

"Those who support Lee Westwood would say he has the ability to do it. What is the missing ingredient for him though? It would be nice to see him take a step forward but the years are ticking by now."

Lee Westwood hadn't managed a birdie on the par fives all week until today, but now he has birdied the first two. The second comes at the eighth and takes the Worksop man to one under.

Par five, 575 yards

A downhill fairway curls to the left towards a green that is reachable in two, though bunkers await those who fall short. South African Louis Oosthuizen took an albratross two in 2012 on the way to a losing play-off against Bubba Watson.

Yep, as Pablo Larrazabal points out, Miguel Angel Jiminez is bang in contention after the lowest round of the week, a 66. He lies three behind the leader Watson, who is heading to the second.
