Spieth moving into a share of the lead seems like a good time for me to point you in the direction of our vote. A very simple question - who is going to win the 2016 Masters. Vote either at the top or side of the page, depending on the device you're using.
-2: Spieth (Through 6), Wiesberger (9), Z Johnson (7)
-1: Dubuisson (10), Jaidee (8), Westwood (8), Oosthuizen (6), Dechambeau (6), Casey (6), English (3), Rose (1)
Selected others: Par: T Watson (7), Fowler (7), Stenson (2) +1: D Johnson (2), Mickelson (2).

Now then! Jordan Spieth is striding away from the sixth like a man who owns the place. For a year, he has. A long, straight one sunk to go to two under and join Bernd Wiesberger and Zach Johnson at two under. The man has played here twice and finished second and first. I wonder...
For Ian Woosnam, can we take a moment for the uppercut salute? When his final putt dropped in 1991...
He did this... Go on Woosie.
Back on the first, from Wales, the 1991 Masters champion...

While Zach Johnson was going the right way at seven, Rickie Fowler was dropping back to level. Already his round has had more ups and downs than Blackpool Pleasure Beach.

Oh yes! Zach Johnson, the Open champion, off the fringe at the seventh. From the longer cut, on to the flat, windy, curvy, dropping into the white abyss. He's knocked in back-to-back birdies and shares the lead.
A few have had chances to get to two under. Paul Casey, Jordan Spieth and Bryson DeChambeau all missed birdie putts at the par-fourth fifth. DeChambeau, you may already know, is the chap who has designed all his clubs to be exactly the same length. Clever fella, a physics major, but with awful taste in headgear. My grandad called, he wants it back...
An excellent mug, a not so excellent coaster. Justin Rose has sped out of the traps, birdieing the first. He's in the pack behind Wiesberger, who has taken a five at the par-five eighth. He's nearly thinking about Amen Corner.

One rascal on Twitter has suggested that we've forgotten England's Chris Wood. We haven't - he's played par golf through seven. Remember how I said that Rickie Fowler has got the worst wardrobe in golf? Today's lime green number would make an elephant nauseous.
Adam Scott, who could forget his win in the driving rain three years ago?
The mild-mannered Australian was tipped to disappear when the long-putter was outlawed from 1 January this year.
He switched to a short stick three months early and has already claimed the Honda Classic and pipped Bubba Watson to the WGC Championship this season.
Despite this, he fancies two-time winner Watson this week: "Even if I won every tournament I play before the Masters, if Bubba keeps finishing second, I'd still think he's favoured. It just sets up so good there for him."
On the tee, from Australia, the 2013 Masters champion...
The list of players on one under has got more names than Tiger Woods' little black book. My man Bernd Wiesberger is still at two under, ahead of a group that includes Spieth, Casey, Fowler, Westwood and Tom Watson.
It's pretty much perfect at Augusta - but you knew that anyway, didn't you? Sunshine on the sort of turf you'd be happy to sleep on. Bunker sand white as a wedding dress, water in the hazards not daring to move. It's like being a sporting Disneyland. Spieth makes that par at three.
