"England began the day batting with a lead and having lost no wickets. Only one team has lost a Test match from the same position. That was Port-of-Spain in 1968 when Garry Sobers made a silly declaration and England beat West Indies."

These are the circumstances when having a man of Moeen's quality at eight can be a true blessing. Saying that, even a class act can lose his discipline in these circumstances. Rabada draws a lose stroke from the bearded one with a ball outside off that he sends aerially for an uncomfortably long period of time before it drops just short of point. Hearts. Mouths.

"It's this weakness, this fault they have in the team. They win some matches, but make a rod for their own backs with batting collapses. There's a fault in the upper batting. There's no solidarity."

You know England are in trouble when the Chuckle Brothers are wheeled out. It's fair to say that none of us are laughing. Bairstow repels another six from Piedt.

Trust Shane Warne to go throwing Adelaide 2006 into the mix. Unfortunately, he's painfully touching a very apt nerve. In that Ashes Test (as I'm sure you'll remember), England scored 551/6 declared and led by 38 after the first innings before being rolled for 129 to lose by six wickets. England are not quite there yet, but they need to dig deep.

Bairstow adds five runs to the total off Rabada. Every run is gold dust at the moment.

Piedt is twirling and looping England a merry dance at the moment. Ali hangs his bat out to shakily pat out a maiden but there is no assurance behind it, only fear. A screw hasn't been turned this tightly since the Rock last put up some shelves.

"It's one of those situations where the bowlers will not be happy. They will be looking the batsmen and thinking 'what have you been doing?'"

There are a lot of grave expressions in that England dressing room. Batting coach Mark Ramprakash is staring into the middle distance, possibly searching frantically for his happy place. Bairstow and Ali survive Rabada's over. That is all they can hope for now; survival.

"How will Moeen Ali play? He's an attacking player. Will he stick to that or will he go into his shell?"

Piedt finishes his over with two dot balls to new man Moeen. What do England do now? They've been knocked down and have made it back to their feet but they are rocking like Homer Simpson when he fought Drederick Tatum.

"That's a big one. Taylor has looked tentative for 20 minutes. That will send a proper shudder through the England dressing room. They could lose this match."

"You just sensed that might happen with the extra bounce. There was a little glove on to the thigh pad."

The new man is Jonny Bairstow, who is definitely not due a failure! England are on the ropes in a game that looked at one stage to be unloseable. There is a renewed skip in the stride of Rabada as he thunders in to Taylor and draws howls of anticipation from a couple that square the batsman up. Digging in.

"It's the balance between wanting to score and making the game safe. England are effectively 117-5, still with a lot batting to do."

"That is a good catch, close to the boundary rope. It's a big wicket, because Stokes scores quickly. He has tried to hit it hard and got a top edge. I don't think he was trying to hit it for six."
