A big shot from Root does finish it!

He skips down the pitch to loft Jayasuriya's second ball down the ground for four, finishing the game with a flourish.

An innings of hard graft comes to an end - it wasn't always pretty, but this was an excellent effort from England.

Not bothered about the average, Joe?

Root goes for an elaborate scoop, but the ball skews off the toe of the bat, his shoulder and falls safely.

I don't think the review would've saved Sri Lanka there.

Woakes brings up England's 200, turning the returning Rathnayake down to third for a single.

The debutant goes up for an lbw as Root tries to turn the ball into the leg side, but Sri Lanka are out of reviews.

It was heading down leg anyway.

The target is now one meaty blow away! Jayasuriya's mammoth effort is nearly over.

Steady accumulation from Jayasuriya's over, as England bring themselves within one shot of victory.

Didn't touch anything.

Good catch though...

Asitha Fernando continues to bustle through, despite the increasingly bleak outlook.

He goes up for a caught behind for Woakes, with sub-keeper Kusal Mendis taking a sharp grab down the leg side.

They'll send it upstairs, may as well with 10 to win.

England are not risking anything here.

By the way, we might not be quite finished here, but Today at the Test is on BBC Two and iPlayer at 19:25.

Tune in if you fancy it, or catch-up later.

The England batters work Jayasuriya for three singles, as they ease within sight of their target.

One big over would do it.

Here's Smith's exit from the match.

He was just keen to get it over and done with.

Nothing more from the over, as Woakes blocks out a final-ball yorker from Asitha.

An extraordinary shot! No-nonsense from Woakes.

Pow!

Woakes cracks a four off Asitha Fernando, not much backlift but he middles it past a diving mid-on, off to the ropes.

Most 50+ scores for England in fourth innings:

• Atherton 11
• Cook 11
• Boycott 10
• Root 10

Woakes sees off the remaining five balls of the over without scoring.

Sun update: it's still sunny.

Root has had to use all his reserves today, patience, skill and control. It's been a fine innings that England have needed.

Fifty for Joe Rootpublished at 51.1 overs

51.1 overs

Root gets his half century before the close.

A single into the covers off Jayasuriya - who's returned with a change of ends - brings up the landmark from 108 balls.

Time for Chris Woakes.

He gets off the mark straight away, turning another full ball from Asitha into mid-wicket.
