3.17pm So, that will be tea. And Sri Lanka's task is about to begin in earnest. They need a hefty 483 to win, or more realistically to bat for seven sessions plus overtime to stay in the series... on recent evidence, they won't be getting their hopes up. For now though, it's all about Joe Root. Just about the only record he didn't chalk off in that innings was Alastair Cook's England runs record, but he's drawing very close now! Just 95 runs adrift, with Sri Lanka's great Kumar Sangakkara next in his sights, a mere 23 away.

Sampath adds: "Only one batter before Joe Root scored hundreds in both innings of a Test match in which none of his team-mates in the Top 7 reached fifty in the match - Glenn Turner vs Australia in 1974 at Christchurch

Peter: "Also Root's 50th International century. 16 in ODI's to go with 34 in tests."

We'll be back in 15 for the start of the endgame.

chandio: "I don't remember if I had ever opened that many tabs in espncricinfo for so many records broken in a single commentary. Absolute Root supremacy "

Ramapriya: "Unless there's some dodgy Wx in the offing, there's no hurry at all for a declaration. Lots of time in the Test still" Well quite

Sumit: "Amazing to see Root struggle to get the ball past the fielders in that over ..." The harder he tries, the less easy it looks

Tea will be taken at the fall of the next wicket, hence there's not much point in a declaration. Free hit territory for England
