Stephen Myler responds quickly and the lead is back to seven points. His kick was somewhat simpler than Daly's.

A monster of a kick from Elliot Daly and Wasps lead Saints by 10 points. It just about the legs to creep over from nearly 60 metres. A fantastic effort.

A great take by Christian Wade from the high ball leads to a couple of knock-ons, with the first infringement coming from Saints. Wasps have the ball but both sides are still making too many errors.

The main threats are coming when the play gets disjointed.

The Wasps scrum stands firm. A bit over eager by Saints and Wasps can clear. They are able to get the line-out deep in Northampton territory.

A brilliant steal by Northampton's Alex Waller, who makes the tackle on Jake Cooper-Woolley and wins the penalty by staying on his feet as his opposite number clings on to possession. Saints now on the attack.

Off we go again. There's a fair chance both bosses will be expecting more from their teams in the second half. 

I suspect Jim Mallinder will think Saints are not seeing out their phases of play or making the most of their territory and Wasps have been on the back foot more than Dai Young would have liked.

This should be a tasty half. Top four places and home semi-final ties at stake.

With the score as it stands at the Ricoh Arena, Wasps will move to within two points of Exeter in second. They will want some more of their expansive attacking play to pay off as they search for a fourth straight bonus-point win.

If Northampton fail to peg Wasps back in the next 40 minutes, they will remain fifth in the table.

Bath will investigate reports that a supporter entered the referee's room to confront the match officials after Friday's defeat by Saracens at The Rec.

The Blue, Black and Whites had England wing Anthony Watson sent off for foul play after half-time in the 30-10 loss.

"Passions were high last night but it's not acceptable for rugby or for Bath," managing director Tarquin McDonald told BBC Radio Bristol.

"Clearly we're looking into it and we'll deal with it appropriately."

So, what's happened in the Premiership this weekend?

Well...

Friday: Chris Ashton scored twice on his return from a 10-week ban as Premiership leaders Saracens beat Bath 30-10, who had England wing Anthony Watson sent off.

Saturday: Exeter Chiefs thumped Worcester 50-12 to narrow the gap on Sarries at the top, while Manu Tuilagi helped Leicester overturn a 17-point deficit to beat Gloucester 35-30.

Sale added to London Irish's relegation fears and Harlequins beat Newcastle to keep their play-off hopes alive.

Rob Miller has the only try of the first half, but there have been several close calls.

Saints have had plenty of territory but Wasps have defended impressively and look the more likely to add to their score on the break.

Craig Hampson has a chance to set up a second try but, after nicking possession and charging away, feeding the ball to Joe Launchbury before Ken Pisi intercepts to save a certain score.

George North bundles through to set up a Saints attack. We are only on halfway but with both sides losing their shape following a couple of breaks that could easily have led to something.

The big Welsh winger is stopped though, allowing defences to get set. There have been numerous nearly things for Saints. 

Quick ball from the line-out and Saints are probing once more. The ball goes from one side to another and back again until finally a knock-on by George Pisi sees the attack end. 

Wasps have looked solid in defence and very dangerous when the play gets messy.

Wasps scrum-half Craig Hampson is showing maturity beyond his years. He only made his Premiership debut against Newcastle last week but is showing real calmness to help his side keep Saints at bay.

Saints showing a bit more control with ball in hand but there's no way through once again. Wasps soak up the pressure and break again. They are back up to halfway.

It's broken rugby at the moment. Mistakes aplenty. Turnover ball everywhere you look. One of these errors will lead to another try soon surely. 

Saints respond immediately and threaten the home line as the game really opens up.

The expansive rugby from Saints led to the Wasps try as they tried a cross-field kick and another misplaced pass almost leads to another canter up the pitch.

Jimmy Gopperth makes excellent yards with a kick to clear to halfway and relieve pressure on the Wasps line. For now.

Stephen Myler's smart kick into the corner puts the home side under pressure on their own try line. 

We have a break in play while Kieran Brookes gets treatment after taking an accidental knee to the head as Wasps try to run the ball clear. He's sitting up now thankfully, but is being replaced.
