Andrew Strauss on TMS: "We're not sitting there and saying 'it will all be alright'. This is one way of providing extra context. There is no harm in trying things.
"We're propping up all three formats. We see quite different audiences for the three formats and this is a way of connecting them together."
Tom Fordyce
Chief sports writer at Headingley
"The sun might be out, but thanks to Shanaka's three wickets in eight balls so too is the the most experienced part of England's top order. This always looked like a morning to bowl but the hosts have made hard work of it all the same. A nervous lunchtime awaits both Alex Hales - fighting for his place - and James Vince, still to get his first Test run after 15 watchful deliveries."

Director of England cricket Andrew Strauss on Test Match Special: "I wouldn't say it's exactly my brainchild. We've got to be cogniscient is cricket is changing and developing very quickly. We need to make sure international cricket evolves alongside that. This is a way of giving more context to every game of cricket that is played. Hopefully it's a way of connecting the formats too."

Hmmm, what to make of all that? Do keep your views coming during the break. While you do that, tune in to Test Match Special. England cricket director Andrew Strauss is in conversation with Jonathan Agnew.

"England will be disappointed. They had such a good start - Sri Lanka didn't get it right for the first 80 minutes. But the debutant got them driving, and although Alex Hales has played well to see it through, it's Sri Lanka's morning."
Eng 57-3
Is that the same man who has taken three for spit this morning? Dasun Shanaka barely gets the final over the morning on the cut strip. Regardless, he's ripped through the top order, giving the honours to Sri Lanka in the first session of the series. At 57-3, there's plenty for England to ponder over the lunch break.
Dasun Shanaka, the debuting destroyer, continues, sliding down what will be the final over before the interval. On the England balcony, Joe Root listens to an earpiece. He looks more gutted than a man who has ordered a pint at last orders, only to spill it on his way back from the bar.

"It's amazing. Think how many runs James Vince has scored in first-class cricket, in one-day internationals and T20s...but when you're on Test match debut, that first run is the one you want."
Spin for the first time, the wily old left-armer Rangana Herath coming into the attack for the first time, testing the debutant Vince. Ball-on-a-string stuff, teasing flight, Vince missing out on his first runs when a cut at a half-tracker goes straight to point. Rapid maiden.
Shanaka continues to skid in, slinging it down with a whippy action, serving up a rare short ball that Hales turns off his hip for four. He looks much less dangerous when dropping short, with Hales able to defend in comfort from the crease. Maybe two overs to go before lunch.

"It was only a few weeks ago that James Vince scored a century on this ground against Yorkshire. He'll be nervous, no doubt - the cameras are on him - but if he can hang around for 20 minutes, he'll start to feel those vibes coming back."
I'm slightly stunned by what I've seen, with the collapse of three wickets for two runs being made all the more surreal by the fact it's been played out in front of near-silence in Leeds. The only noise has come from the whoop-whooping or the Sri Lankans. Vince is welcomed by a pacy short ball from Chameera that rattles him on the gloves. England, already in trouble, would be deep in the soup if they lose another before lunch.

Sam Shepherd: England batsmen just making sure Vince gets an opportunity.
Si Lomas: Awful batting from England, Shanaka is just a dobber, they've tried to smash him out of attack on debut and handed 3 wickets!

"Dasun Shanaka might not yet be a household name, despite the wickets of Cook, Compton and Root in two overs, but he has a better chance now than he would had he used his given first name, which is Madagamagamage."
The ridiculous thing about this is that all of England's players will have see plenty of this sort of bowling in county and even club cricket. No great pace - mid-70s - full length, tiny hint of wobble. Nothing more. Looking again, Root was drawn into driving one that just moved at the last minute. The sort of shot to be playing when you've just arrived? James Vince, padding up in a rush on debut, sees off the rest of the over.

"It's the perfect ball at Headingley: full length, hint of movement, kissing the top of the surface. Root went at it with hard hands."
Root c Silva b Shanaka 0 (Eng 52-3)
Unbelievable. What is going on out there? England are being destroyed by the Sri Lankan equivalent of Mark Ealham. It's awful from Joe Root, driving at a full delivery, getting a thick edge to gully. Dasun Shanaka, on debut, has 3-1! Plenty will focus on the duck of Nick Compton, but now the vice-captain has followed the captain in playing a loose stroke.
