Wiaan Mulder out in the middle early at number three - he was bowled for six by Pat Cummins in the first innings.

He faces a couple of dot balls then edges past third slip for four.

Mitchell Starc has certainly put himself in man of the match territory. I thought it'd hit the ground and nothing else but what a dismissal.

Strange dismissal.

The Aussies are celebrating, they clearly think it was out.

It was a very full ball.

Has Ryan Rickelton edged behind?

Nothing from the umpire, but every Australian behind the wicket went up for the caught behind.

We'll take a look.

Rickelton retained the strike at the end of the previous over, so he faces Josh Hazlewood.

Three slips in, and the opener edges the second delivery just short of the cordon - we saw a lot of that happening yesterday.

Markram gets South Africa on the board immediately, taking a single to mid-off, before his opening partner Ryan Rickelton turns the ball square for the first four of the innings.

Anti-Australian? Moi?

I love Australia - from the majesty of Sydney Harbour to the beauty of the Outback. From their magnificent climate to their curiously large number of men called Lachlan.

Righto - the players are back out there.

The target for South Africa is 282.

Mitchell Starc has the ball in hand, Aiden Markram will face.

Here's how the Australian innings came to an end, with Josh Hazlewood caught off the bowling of Aiden Markram.

I'm not sure how many English cricket fans tend to enjoy an Australian batter scoring a fifty... but here's how Mitchell Starc possibly took the game away from South Africa.

One of the best things about Lord's is all the nooks and crannies where you can drink in the fantastic cricket history of the place.

In a building opposite the back of the iconic pavilion you have to ascend 39 steps to reach possibly my favourite place at the home of cricket - the Marylebone Cricket Club (MCC) library.

The shelves practically creak under the sheer volume of literature from all across the globe. There are rare pamphlets, books dating back to the 1800s, every edition of Wisden, and more.

You can also be assured of a warm welcome by the MCC's archive and library manager, the amiable Alan Rees, who is an absolute font of knowledge on the game.

Well worth a visit.

Thanks Elizabeth.

I was wondering at one stage yesterday afternoon whether this match would even still be being played when I was scheduled to come on.

Now, who knows - maybe even day four?

And on that note, I'm going to go on the hunt for lunch.

Here's Mike Peter to take you through the rest of the interval and the afternoon session.

Paul, that's brilliant.

Anon, I've no idea what to do with that information.

Should South Africa pull this off, it would be the second-highest chase to win a Test match at Lord's, just above the 281 that England needed to beat New Zealand in 2004.

The highest chase at the ground was the 342 that West Indies chased - at the loss of just one wicket - to beat England in 1984.

Well, that was a thoroughly enjoyable session of cricket, possibly my personal favourite of the match so far.

What a knock from Mitchell Starc, who finishes unbeaten on 58 (136) and shared big partnerships with Alex Carey and Josh Hazlewood.

Remember (and sorry Marco for bringing this up again), he was dropped by Jansen on 14 last night.

How costly will that error, the no-balls (20 across the two innings), and the missed review against Beau Webster in the first innings prove?

I was thinking he would have to bowl it slower and wider but that was a good fast ball.
