"Bairstow is just playing the quiet role. I've just been stood behind the bowler, it's been incredible, he can hit it wherever he wants."
Former South Africa spinner Pat Symcox has his say...
Imagine what those rich owners in the Indian Premier League are doing now. I like to think they're sat with their cat on their knee, quaffing truffles and phoning their fixer.
'Get me that Stokes now. For one million dollars.'
More runs. Again Kagiso Rabada drops short and again Ben Stokes rocks back and clubs four through mid-wicket like a caveman knocking the living daylights out of a walrus.

Neale Pye: Do you think the SA players said something derogatory about red headed cricketers recently?
Lewis Squires: So when does the Test match series start then?..
Hashim Amla has still got two slips in place for Jonny Bairstow. They're about as much use as a chocolate fireguard when the bowlers are sending down pies.

AxminsterTownCC: Not many better centuries on tour in my lifetime. Brilliant from Stokes.
A Tweeter: Smiting, a word not used nearly enough. Maybe that should be his nickname a-la darts - Ben 'The Smiter' Stokes!
Image source, Rex FeaturesI'm running out of superlatives to describe Ben Stokes, who muscles Kagiso Rabada's short ball to the boundary wide of mid-on.
The Russell Crowe of English cricket. An absolute gladiator.
Is there anything this lad can't do? I sense some Stokes memes here. Send them in using #bbccricket or email tms@bbc.co.uk.

"The fifth time Bairstow has played against South Africa, the fourth time he has got to 50. It has taken just 28 balls for the partnership to go from 100 to 150."
Eng 369-5
Another fifty for Jonny Bairstow, who is merrily bobbing along in Ben Stokes' slipstream. He averages 80 against South Africa (three Tests). Not bad for a number seven.

The best thing about this sustained assault from Ben Stokes? He's played proper cricket shots and toyed with the field like a cat pawing a mouse. When Morne Morkel pitches the ball up, Stokes belts four back over mid-off. Carnage.

Ian Bradley: Last day of Christmas break and last lie in happily sacrificed to see Stokes pillage a century, brutal.
Rob Meech: I don't think the 'nervous 90s' really applies to Ben Stokes!
Mike Brookes: Ben Stokes. Take a bow! That is top top quality!

"There have been 45 runs in four overs this morning. Chris Morris since the new ball has gone for 61 runs in six overs."
This is gladiatorial from Ben Stokes, who celebrated his three figures by removing his helmet, raising his bat and milking the applause. The South Africans are putty in his hand. He hits Chris Morris for two more fours, helped, it must be said, by some pretty dreadful fielding.
The Proteas are meekly surrendering here.

"Third Test hundred for Stokes from 105 balls with 16 fours and a six. His last 50 came from just 35 balls."

"Superb innings. Took the game by the scruff of the neck. And he can bowl as well!"

Ben Stokes is lighting up Test cricket here. People will soon stop talking about middle to lower order batsmen 'doing a Gilchrist' and instead refer to 'a Stokes-like innings'. England's strapping all-rounder has taken the game away from South Africa with the calculated ruthlessness of a mafia hit man. He brings up three figures with a three. Soak up the applause, young man.
