We're OK to continue seemingly, and Nathan Lyon sends down a maiden, bowling to Aiden Markam.

It only take a partnership or two and they could come back tomorrow and knock off 50 with another six wickets left

Hmm, end of Mitchell Starc's over (five from it) and I'm not sure what's going on here.

Temba Bavuma is on the floor, pads and tros off (he's wearing long shorts underneath - fear not, modesty fans), and the physios seem to be working on his hamstrings.

Meanwhile an Australian player is getting a massage on the boundary - Lord's is turning into a giant spa.

Three for Temba Bavuma, edging Nathan Lyon past the slips.

Usman Khawaja chases the ball down - meanwhile South Africa now need less than 200 as the over goes for five.

A quieter remainder of the over, with the South African batters working Mitchell Starc around for four more runs.

By the way, from the ball prior to that drop, Markram skewed a shot aerially, but it dropped a little way short of the point fielder.

Meanwhile Sam Konstas is on for Steve Smith, who went off injured after dropping Temba Bavuma at slip.

He was trying to push it leg-side and that generated even more pace.

Put down!

A short delivery from Mitchell Starc, angling into the body, which Temba Bavuma tries to drop into the leg side.

The ball takes a leading edge and skews into the slips, where it's put down by Steve Smith under the helmet.

Smith looks in considerable pain and heads off the field immediately - I'm not quite sure if it's his finger or his shoulder, which he's injured and has had surgery on previously.

This is such an important half an hour before tea, you don't want to lose wickets and the feel like you're two wickets behind

Aiden Markram takes three off the first ball of Nathan Lyon's over, cutting a short ball through point.

Bavuma faces the remaining five, and edges past his leg stump with a big waft.

Out comes captain Temba Bavuma and he starts with a statement of intent, lashing his second delivery expansively over the covers.

The ball is cut off before it reaches the boundary and the batters run two - that puts South Africa a quarter of the way to their target of 282.

Wiaan Mulder took an absolute age to trudge off after he got out and went through the full repertoire. Thudded his pad with his bat. Check. Head rolled back and a look to the heavens. Check. Cursing under his breath. Check.

A lot of us didn't think Mulder would be able to bat at three but he is going along so well.

Three more from this Nathan Lyon over, with the Australian spinner going for 0-10 from his four overs thus far.

A tidy over from Pat Cummins, three from it.

Steve Smith is fielding at first slip with a helmet on, in attempt to counteract the lack of carry to the cordon we've seen in this match.
