How has Mendis got four for that? He no more than prods at Finn's first ball and sends the ball trickling past the bowler and away to the rope almost in slow motion. The second four of the over is much more emphatic - an on-drive, complete with checked and held follow-through. New man Dinesh Chandimal watches on admiringly from the non-striker's end.

"Silva has been so good at leaving this morning, but this was great line and length from Anderson - fifth stump, moving away. Silva kicked the ground as he left, he knows he should have left that one."

Finn has less control of the moving ball than Anderson but he remains a serious threat to Sri Lanka. Silva has to dig in to fend off some sharp movement before working a single with a little tickle down to fine leg. Meanwhile, on the Western Terrace...

Jimmy remains bang on the money. The Sri Lankan pair work in singles but every shot is checked.

"Geoffrey Boycott has a milking stool in the hallway of his house."

I don't know what to say about this. I'm just putting it in for you to deal with.

The first bowling change of the day brings Steve Finn into the attack in place of Stuart Broad. He starts full and Silva capitalises with a straight drive that beats the bowler and needs to be chased down to keep it to three. The big seamer is also getting some movement.

And now we have a few glimpses of sunshine, which is probably a huge benefit to the five fellas in the western terrace dressed as the Spice Girls (classic era - Union Jack dress, etc). Jimmy continues to keep the Sri Lankan pair guessing with his swing. Just the one run added.

Tom Capes: Any W Indies combo 75-85 would do it, but our Ashes 4 man Wolfpack in 2005 was the most relentless I've seen England be.

John Rodway: Ray Lindwall and Keith Miller would take some beating as best pair.

Lyn Chandler: Truman/Statham, was a great partnership from my youth.

Hands on shoulders for Broad. Silva's open face steers another boundary through the slips. There is some blue sky now over Headingley.

England are already up and running. Here is how it happened...

Anderson and Broad are having a beat-the-bat-off. Jimmy's first three balls hoop past the outside edge of Mendis' bat. 'I've had enough of this', thinks the batsman before hammering one over mid-on for four.

Next ball? Right past the outside edge. 'Get back in your box' is the message from England's leading wicket-taker.

Tom: McGrath and Warne were great. Stopped runs and took wickets.

Benjamin Hillier: Larwood and Voce were so feared that diplomats had to get involved!

Mike Bell: Best bowling partnership? 1970s. Me one end back garden, my brother Kev at other, Dad batting. Dad also umpire, no LBW in 8 years.
