You don't need a ground pass to start negotiating your way around the outside courts.

There are 12 glorious streams of video goodness, more than ever before, flowing direct from SW19 onto the BBC Sport website for you to skip around.

You can access them, along with BBC Radio 5 live commentary, from this very page.

Court 18 has a couple of intriguing matches at either end of the day.

After last year's quarter-finalist Sloane Stephens takes on 2012 quarter-finalist Maria Kirilenko, Michelle Larcher De Brito, the high-decibel Portuguese who upset Maria Sharapova last year, takes on 28th seed Svetlana Kuznetsova last on.

The 43-year-old Kimiko Date-Krumm, who made the third round last year, will try to stay one step ahead of Father Time as she plays Russia's Ekaterina Makarova. That is first on Court 17.

Full order of play is available on the BBC Sport website.

While the show-court show-ponies get going at a fashionably late 13:00 BST, racquets are unsheathed on the outside courts at 11:30 BST.

British number two Dan Evans will fancy his chances of upsetting Russian Andrey Kuznetsov third on court two.

On court 12, Dustin Brown, who beat Rafael Nadal in Halle last week, will take on the swash-buckling Marcos Baghdatis second on Court 12.

While the early-arrivers best get down to Court 19 where French Open semi-finalist, bon viveur and regular racquet wrecker Ernests Gulbis is taking on Jurgen Zopp.

A no-show so far from Andy Murray down on the practice courts.

He was due down at 10:00 BST, but may have switched inside, away from the prying lenses of the snappers.

Or he may have been diverted, Clark Kent-like, to an emergency on his way into the All England Club.

Murray revealed to BBC Sport yesterday that his Sunday morning practice was a little later than scheduled as he stopped en route to Wimbledon to round up a loose dog and return the runaway to his owner.

Probably quite a good warm-up. Like Rocky chasing those chickens.

"The gates are open," booms the mysterious voice of Wimbledon over the tannoy around the ground.

Impeccable elocution. Impressive volume.

Five-time Wimbledon champion Serena Williams turned up 15 minutes early for her first practice session of the day. The American, in a fluorescent yellow top, didn't look too happy has she strolled onto court, but wasted little time getting down to business.

After a few light rallies, Williams immediately started injecting power into her deep groundstrokes. Meanwhile, there's just one empty practice court left as Britain's Andy Murray has yet to make an appearance.

A smart bit of scheduling that from the Wimbledon organisers.

Second on court means that, barring any major Murray-Goffin dramas, Li Na should muddy her trainers for the first time today at around 15:00 BST.

That is 22:00 in Beijing and a prime evening slot back in her homeland for the Chinese superstar.

Twenty-three million Weibo followers, 116 millions viewers of her 2011 French Open champion, sponsorship deals worth a reported £28m.

Those are the sort of number that can tilt an order of play.

You can read more of the marketing phenomenon that follows Li Na in her homeland on the BBC Sport website.

Following Andy Murray on the centrepiece court we have women's second seed Li Na taking on Paula Kania followed by last year's runner-up Novak Djokovic against Andrey Golubev.

Court One goes a little something like this:

Two-time Australian Open champion Victoria Azarenka v Mirjana Lucic-Baroni;

Queen's champion Grigor Dimitrov v Ryan Harrison;

Everyone's favourite Frenchman Jo-Wilfried Tsonga v Jurgen Melzer

A lot has happened since.

Murray has lost his US Open title, lost coach Ivan Lendl and lost a niggly part of disc in his back.

Will he be able to keep hold of the Wimbledon crown he worked so hard to pin down?

Belgian world 105 David Goffin will be the first man trying to derail the champion. They knock up for the first match on Centre Court at 13:00 BST.

Yes, it really is almost a year since Andy Murray walked into the scorching heat of a sun-bleached Centre Court with the eyes of a nation on his racquet and a ton of British sporting history on his shoulders.

His grandparents Roy and Shirley back in Dunblane couldn't help him. His mother Judy in the players' box couldn't help him. Those crowded around screens all around Britain couldn't help him.

Turned out, this time, he didn't need any help.

He returned, three straight sets later, with his place in history bagged up and that big SW19 ogre slain.

Just before 14:00 BST on 7 July last year, pensioners Roy and Shirley Erskine came inside and settled side by side in front of their television.

On the hottest day of the year so far, they would normally have been pottering in their garden, soaking up the midsummer rays. But, like more than 17 million others around the country, they had a match to watch.

Three and a half hours later, as the Scot lifted the trophy, both Shirley and Roy agreed that Andy Murray had played very well and thoroughly deserved his win over Novak Djokovic.

Shortly after the phone rang. It was their grandson. And Britain's first Wimbledon men's singles champion for 77 years.
