Ben Spencer off, Richard Wigglesworth on.

No offence to the Saracens number nine, but that is arguably a step up in quality coming on.

They're yet to trouble, or get close to, the try line but the boot of Nick Evans is giving Harlequins hope.

Phase after phase of Harlequins attacks have been repelled by Saracen's defence.

Some of the best in Europe have struggled to break down the wolfpack but their line line speed at the moment is incredible.

He was in the wars in the first half and now Mako Vunipola makes his way to the bench for Saracens with his leg very heavily strapped up.

Titi Lamositele is on for the big man.

Five from five now for Owen Farrell and this is probably the best of the lot. 

From distance, on an angle on the right, his hefty swing of the right leg guides it through the posts.

I'm sure this was a result that few saw. 

The West Country side led a couple of times at Sandy Park but Exeter hold onto second place with a late try.

In their first ever 'home' game away from the Recreation Ground, Bath rallied late on to come from behind to beat Leicester.

In front of over 60,000 people Anthony Watson scores two late tries for the four points.

Anthony Watson soaks up the adulation from Bath fans after his two late tries sealed a crucial victory over Leicester.

Watson tells 5 live it was an "unbelievable" win, and is philosophical over his Lions prospects: 

"Whatever happens on the 19th, happens," he said.

Two tries for Saracens who have been very Saracens-y in that first 40 minutes.

Chris Ashton and Schalk Brits with the tries, with three Nick Evans penalties keeping them in touch in from of a maybe two thirds full Wembley.

Oh dear Alex Goode.

Usually so reliable with everything he does, he spills a Nick Evans high bomb from a free-kick and Harlequins have a scrum on the edge of the Saracens 22.

The England number 12, playing fly-half today, makes it four from four for the afternoon in what has been a typically assured start for Owen Farrell.

Five minutes to go until half-time.

We bigged him up pre-match. There has been talk of a Lions place. But this isn't great from Chris Ashton.

Joe Conlon with the initial break, he gives it to Alex Goode and then the full-back fizzes it high to Ashton who knocks on with the try line gaping.

It was slightly high but you'd expect Ashton to gobble that up.

Exeter prevail in a truly wonderful game of Premiership rugby.

They are now within five points of the champions.

Nick Evans is three from three as the moves fourth in the all-time Premiership points scorers list.

Another Maro Itoje conceded and Nick Evans does the honours from the tee.

Simple enough kick and it at least keeps the scoreboard ticking over for John Kingston's side.

On first viewing it looks as if Saracens have a second try.
