Alex Lozowski is a relieved man. After missing two of his three kicks, he makes the most challenging.

Overall, though, I think Worcester will be happy with how things are looking.

Another chance for Alex Lozowski right on the left-hand side. Probably his most difficult of the day. Can he get it over and take them into a half-time lead?

Owen Farrell is missing for Saracens with a back injury, and his replacement Alex Lozowski hasn't covered himself in glory so far today.

He misses his second of three penalties - this time from 40 yards out straight in front of the posts. I'd hate to be in that Sarries dressing room at half-time.

"He'll be fuming there Chris Ashton. Four on two, you practice that at school and as a warm-up. For the best team in the Northern Hemisphere not to be able to complete that is a massive error."

Unlike the 69 points scored at Kingsholm last night, we haven't exactly had free-flowing rugby today, and again Saracens come up short because of handling errors. 

Marcelo Bosch ran towards the line with two on the overlap to his right, but he should have played the ball earlier before being tackled - then under pressure he chucks the ball out of play.

Chris Ashton ain't a happy bunny.

After going to the TMO, Kruis is adjudged to have knocked the ball on.

The chance came after some superb handling from Saracens, playing the ball out to Chris Ashton, but Worcester held him up with two metres to the line before Kruis tried and failed to bundle over.

George Kruis has grounded the ball for Saracens, but is it over the line?

"These players need to have a bit more confidence in the way pre-season has gone. I know it's a big stage but one team needs takes a risk and really go for it to open up the game."

Surprised by this score so far? 

Worcester Warriors didn't exactly come into this game in great form, having lost by 31 points against Munster in their pre-season friendly at the Irish Independent Park on Friday, 26 August.

On the field, we have a scrum. I've lost count of how many that is now.

It's a real battle, this game. Both sides are forcing turnovers and errors from the opposition. Saracens are struggling to keep hold of the ball, which is unusual.

This game is exactly what Worcester would have wanted. Lots of breaks in play so far, and now they are level thanks to Ryan Lamb's penalty.

Smack bang in the centre of the sticks, that one.

Something that has certainly impressed me so far is Worcester's defence. They are fronting up to Saracens and not allowing them to get into their flowing stride. If they get into that, there can be no stopping them.

"Off the base of the scrum Billy Vunipola is one of the best at breaking off the back. And he's now got the ability to throw the offload so the point of attack changes immediately."

Worcester prop Niall Annett is penalised for being off his feet and Alex Lozowski has the chance to kick another penalty from pretty much the same position as his last.

Despite landing his first, this one goes left of the posts.

It's clear from the early stages that Alex Goode is running things for Saracens today. He punts the ball forward for Chris Ashton, but Worcester do well to get the ball away with the big man bearing down on him.

Wait a second, they're all big...

We haven't seen much of Worcester's new signing Ben Te'o so far today, but the rugby league convert breaks down the right and looks to be in for a try before Alex Goode does exceptionally well to get back to him and bring him down.

Worcester centre Jackson Willison is penalised for being off his feet and Alex Lozowski, making his debut after joining from Wasps in the summer, kicks his first points for Saracens.

Alex Goode breaks through the Worcester defence and offloads to Richard Wigglesworth, but his subsequent pass out to Chris Ashton is just behind his team-mate. Sarries showing how dangerous they can be early on.

Saracens are the first of either side to have a prolonged period in the opposition 22, but Worcester face up well to them and Sarries' new arrival Schalk Burger drops the ball forward in a tackle to bring an end to that passage.

The referee is having a word with both sets of players after resetting a scrum. It's not quite clear what is going on, but we can just presume the dark arts of the scrum are coming into play.

Saracens are then awarded a penalty after Worcester are deemed to have collapsed the scrum and they kick for territory.
