Time for us to head back into the BBC Sport clubhouse and recharge our batteries before tomorrow.

But if you're not ready to go to bed yet, here are a few Masters-related things to keep you entertained....

• Superb Spieth takes commanding lead - report
• See when your favourite player is back out the course - tomorrow's tee-times
• Sergio's unlucky 13 - listen to how the drama unfolded

We'll be back from 13:30 BST tomorrow - see you then!

Leader Jordan Spieth was asked if yesterday was his finest round at Augusta: "It was up there, I birdied 17 and I told (caddie) Michael we got a chance to tie our record. It's up there with the top three rounds I've played here," he replied.

"I like that I am going off earlier tomorrow, we caught a really good break today with no wind. I told Michael I wanted to shoot three under every day but that's not going to be easy with the way the course has of bringing everybody back."

There was a little bit of concern that we'd over-hyped the Masters but the way it panned out with the latter groups, particularly with Spieth's run of five birdies, and the big name players coming through, it's set up nicely.

-6 J Spieth (US)

-4 T Finau (US), M Kuchar (US)

-3 R Cabrera-Bello (Spa), A Hadwin (Can), C Hoffmann (US), Haotong Li (Chi), R McIlroy (NI), P Reed (US), H Stenson (Swe)

A sly fist-pump from Cabrera-Bello before signing his card on the final green shows how happy he is with his opening round. The three-under 69 is the Spaniard's best round at Augusta in his third Masters.

Rafa Cabrera-Bello leaves himself with a bit of work to do, but handily gives Justin Rose a guide to the hole. In-between the Spaniard's ball marker and Dustin Johnson's will do just nicely. Rose guides it through the gates and into the hole, signing off with a birdie and for a level-par 72.

Oh dear, oh dear. Dustin Johnson's chip on from the side ends up on the lower tier of the green, leaving him with a horror putt to save par. Not a bad effort to be fair, just coming up a feet or three short.

Justin Rose has a sniff of a birdie with an 18-foot putt on the last, sinking that will leave him level-pegging with Augusta.

Dustin Johnson is not faring as well, booming out a loud "Fore!" as he ball squirts left.

None of the lads behind can catch Spieth, although Rafa Cabrera-Bello could still take a share of second place.

The Spaniard is sitting pretty in the centre of the 18th green for two, but must convert a 53-foot putt if he is to record only the 10th birdie of the day on the last.

Ahhh, another stunner from Jordan Spieth. A gentle, precise swing of the wedge from the left side of the green leaves him with a simple tap-in. He escapes with a bogey on the last, signing for a six-under 66.

The 2015 champion is our overnight leader, two shots clear of fellow Americans Tony Finau and Matt Kuchar. That's the third time in four years that Spieth has been the overnight leader after day one at Augusta.

Rory McIlroy signed for a three-under-par 69 - his best opening round since 2011.

He said: "I played a solid round, not many mistakes. I birdied three of the four par fives, four birdies, one bogey overall and to shoot something in the 60s, I'm really happy with that."

On his birdie on the par-five 13, after landing in a greenside bunker with his second shot, he said it was the "best up and down I've made all year".

He added: "If you shortside yourself, you're in trouble. They (tournament officials) turn something on overnight because those greens are firmer and faster than what we were practicing on."

Nothing is dropping for Dustin Johnson today. The world number one is getting himself into positions, but can't convert with the short stick. Another birdie chance slides by on 17, while Justin Rose drops back with a bogey.

Rafa Cabrera-Bello is the in-form man among this trio, three birdies in four holes putting the Spaniard into that seven-strong pack in tied fourth.

Spieth has a fairway wood in hand and gives his ball a good old wallop as he chases the 18th green. But he's pulled it left and sends patrons scurrying. A dropped shot at least looks to be on the way...

You know I was only joking when I asked if any bookies were paying out? Right?

Spieth's ball has landed behind a bush... no getting over that. He has to knock out sidewards onto the fairway, leaving him 219 yards short of the green.

"Up and down Jordan, up and down," says one encouraging, if very hopeful, voice from the crowd.

But wait! Jordan Spieth has hooked his tee shot on the last into the trees on the left. Big bother for the leader...

Rory McIlroy tugs his approach on the last left, knocking a precise chip back to within a few feet. Some top-drawer scrambling from the four-time major winner today.

He knocks that in to complete a very tidy card - four birdies and just the one bogey. He said he wanted a fast start and that's only his second sub-70 opening round at Augusta.

Unfortunately for him, Jordan Spieth is sprinting out ahead in front of him.

Here's one stat fans: Jordan Spieth has never birdied the 17th at Augusta. Neither have I.

Guess what? Spieth has a golden chance of putting one over me here. The ice-veined Texan drills a seven-foot putt straight down the middle, that's a career-best fifth birdie on the bounce in a major.

Any bookies paying out yet?

Matt Kuchar rounds off a brilliant back nine by sinking his fifth birdie, propelling him into a share of second spot with Tony Finau.

His compatriots Mickelson and Fowler can't add to their tallies on the last, nevetheless these three will be happy with their work when they chat about their rounds over an ice-cold bev.

Justin Rose's charge has stalled a little with successive pars on 14 and 15, while Dustin Johnson also impressively pars the 15th after plopping his second shot in the drink.

McIlroy's putter has been as hot as a poker on this back nine too. Not quite as red as Spieth's, but still. Chasing the Rory Slam remember, he saves a sandy par after finding the trap at the front of the green and needing his putter to rescue a seven footer.
