London Irish 3-0 Harlequins
No doubt London Irish will be happy with that start. They have settled well and are dominating territory.
Can they put 18-year-old Quins fly-half Marcus Smith under pressure? That must be in the gameplan.
London Irish 3-0 Harlequins
First points for the Exiles.
Not the easiest kick, but Tommy Bell just about slots over from the left.
Wasps 43-28 Sale
Image source, Rex FeaturesThe home fans are breathing a little easier at the Ricoh Arena.
England forward Nathan Hughes to the fore as he charges forward and Will Rowlands is there in support to score near the posts. Jimmy Gopperth converts.
"Surely that clinches the game for Wasps," said BBC Coventry & Warwickshire's Geoff Foster.
London Irish 0-0 Harlequins
It's been a good start by Premiership newcomers London Irish.
And they have a penalty...
London Irish 0-0 Harlequins
Harlequins receive and clear their lines to halfway but fail to find touch.
When Irish put the pressure on Quins full-back Mike Brown, he gets an unlucky bounce and knocks on.
Irish have a just outside the 22.
Wasps 36-28 Sale
Only 11 minutes left at the Ricoh Arena and the ball is in the Wasps half.
Thankfully for the home side they have a scrum and a chance to clear their lines.
London Irish 0-0 Harlequins
This game will have something to live up to given the try-fest served up in both today's other games.
Let's see what we can do. We have Twickenham kick-off. Over to you London Irish and Harlequins.

Kick-off is moments away.
London Irish v Harlequins (16:45 BST)
We are less than five minutes from kick-off in the second game from Twickenham this afternoon.
Wasps 36-28 Sale
Image source, Getty ImagesWasps have been ringing the changes, with England lock Joe Launchbury among those to be replaced a few minutes ago.
He's now joined on the sidelines by Christian Wade, allowing Marcus Watson to make his debut.
Can the fresh legs see Wasps over the finishing line?
Wasps 36-28 Sale
This has been an impressive second-half comeback from Sale, who looked out of it when Dan Robson went over for his fourth try.
How much to have have left in the tank for a final push?
Wasps 36-28 Sale
Hello! There's a quarter of this match to go and suddenly this is an eight-point game.
Sale have their four-try bonus point too as Faf De Klerk marks his Premiership debut with a try.
Once again AJ MacGinty makes no mistake from the tee.
Wasps 36-21 Sale
Image source, Getty ImagesSale aren't out of this one yet. Replacement TJ Ioane makes a real impact with a bullocking run.
Wasps are penalised for offside and the Sharks take it quickly to put Denny Solomona, who make his England debut on the summer tour of Argentina, in.
AJ MacGinty adds the conversion. There's 15 points in this.
Wasps 36-14 Sale
Image source, Getty ImagesAnd Dan Robson won't have the chance to equal that record as he and Danny Cipriani head off the field, to be replaced by Joe Simpson and Juan De Jongh, who is on for his Premiership debut.
Wasps 36-14 Sale
Dan Robson might have four tries for Wasps this afternoon, but he still has some way to go in the individual try-fest stakes.
BBC Coventry & Warwickshire's Geoff Foster points out that Christian Wade scored six tries as Wasps won 54-35 at Worcester in April 2016.
That equalled the Premiership record for most tries in a game, a record Wade shares with Saracens' Ryan Constable, who scored six against Bedford in 2000.

BBC Sport at Twickenham
Image source, Rex FeaturesLondon Irish are back in the big time after a year away from the top table.
Their charge to Championship promotion last season was built around focus and determination from every single member of the squad to buy into director of rugby Nick Kennedy's masterplan.
Now that the Exiles are back in the Premiership, there's a realisation that they will have to up the intensity and ruthlessness of their game, but also a belief they can cause several teams a problem this season.
A first London Double Header win at Twickenham today in seven years would be a decent way to start going about that.
Wasps 36-14 Sale
What an afternoon for Dan Robson! Like with the game's first try, Christian Wade makes a break and who is it but Robson on his shoulder to take the pass and cross for his fourth try of the game.
He's earned a bonus point by himself.
For the first time this afternoon, Jimmy Gopperth's conversion attempt is wayward.
Former Harlequins number eight told BBC Radio 5 live: "Marcus Smith is a supremely talented guy, he's got a wise head on his shoulders and fully deserves his chance today.
"If you're good enough, you're old enough."
Wasps 31-14 Sale
We're back under way at the Ricoh Arena, with Danny Cipriani kicking us off.
Are we in for a dull second half? With the way today's games have gone so far I would suggest not.
London Irish v Harlequins (16:45 BST)
Image source, Getty ImagesHere's how the teams are lining up from the final game of three today.
Second-row Franco van der Merwe makes his London Irish debut after signing on Thursday.
