Foakes 85, S Curran 21
John Hastings' last over begins with Ben Foakes angling a shot for four down to third man.
Surrey reach 350 as he bowls a wide down leg but Foakes survived what looked a close leg before shout the ball before.
Sam Curran sprints a couple and dives in just in time to avoid being run out. A dot ball from the last delivery sees Hastings avoid the embarrassment of going for 100+ runs.
He finishes with 1-97 off his 10 overs.
Surrey 342-5 (Foakes 85, S Curran 15)
So, what will Surrey post here with two overs to go?
Remember - Essex 370-5 last night against Nottinghamshire wasn't enough to win at Chelmsford!
Foakes 85, S Curran 15
Sam Curran in the boundary business at the start of Joe Leach's over.
Tries to flat-bat a pull shot but can only toe-end behind on the bounce to wicket-keeper Ben Cox.
Next ball, he does get four as he shimmies around in the crease and paddles it down to the fine leg boundary. Finishes off the over with a cracking four over extra cover.
Surrey take 14 from that over.
Foakes 83, S Curran 2
John Hastings keeps bounding in from the Diglis End, but he may end up going for a ton today as Ben Foakes follows up that six with a four straight back past him.
He did have Foakes swinging and missing earlier in that over though with some slower balls, but then his last two deliveries cost 10 runs. Who'd be a bowler in this game hey?
Surrey 324-5 (Foakes 79, S Curran 2)
Big pull shot over the ropes for Ben Foakes sees John Hastings take more punishment!
Foakes 72, S Curran 1
Sam Curran the new man in for Surrey after Ollie Pope's dismissal, so one 19-year-old replaces another in the middle.
Gets off the mark first ball with a pull shot for a single. But, swishes at a couple later in the over.
Good over from Joe Leach, took a wicket and only conceded four runs. Vital at this stage.

Ollie Pope was looking to get underneath it because Joe Leach got some good bounce on it and it was very hard to keep control of and he ended up skying it.
Right decision by Pope but he's just got done by a really good delivery.
Surrey 310-5
Joe Leach back on to bowl for Worcestershire and he gets Ollie Pope first ball as he tries to smash away a short ball.
Pope doesn't time it and spoons up an easy return catch for Leach.
Foakes 70, Pope 22
Five overs to go then and Foakes and Pope have a 50 partnership in lightning-quick time, just 36 balls.
Another bruising over for John Hastings costs him 13 runs.
Surrey 308-4 (Foakes 69, Pope 21)
300 up for Surrey as Ben Foakes hits a great straight drive away over John Hastings' head.
Next ball, he gets one in the slot and lofts it away over long-on for an impressive six.
Surrey 297-4 (Foakes 59, Pope 20)
Moeen Ali has played a huge role in slowing Surrey's run rate. He took the first wicket of the day and, as mentioned, his 10 overs cost just 55 runs for Worcestershire.
In the context, coming on as he did with the ball flying to all parts, that's a very tidy effort.

Moeen Ali's last over begins with Ben Foakes clipping him away for four down to mid-wicket. He's played that shot beautifully in this innings today.
Ollie Pope lofts a ball deep into the covers that drops safe and gets him a couple.
Nine runs from that over and Moeen's figures are 1-55 from his 10 today.

Foakes 53, Pope 17
Surrey looking to push up the momentum here, but a crucial dot ball closes John Hastings' over.
Worcestershire just keeping the lid on things a touch with seven overs to go.
Surrey 281-4 (Foakes 50, Pope 12)
Image source, Getty ImagesHalf-century time for Ben Foakes, his sixth in seven innings in this competition this season.
He just survives being run out though as he takes the quick single off John Hastings.
It's come off 51 balls and included five fours from the Surrey wicket-keeper.
Surrey 278-4 (Foakes 49, Pope 11)
Take that Moeen Ali!
A big shot for six from 19-year-old Ollie Pope gets him six. Skips down the track and hammers him into the stands, into the press box down at long-on.
Lovely striking.
Foakes 47, Pope 2
John Hastings continues with his tail up after dismissing Kumar Sangakkara in his previous over.
Five runs from that set of six deliveries. Surrey again just having to do some consolidation as they look to build a new partnership.

That short ball ploy working there from Worcestershire with John Hastings again going for the bang-in delivery into the middle of the surface, slightly down the leg side.
A nice catch from Ben Cox, diving to his right at full length and managing to get two hands onto the ball.
That's a huge wicket for Surrey and for Worcestershire.
Foakes 43, Pope 1
Ollie Pope the new man in for Surrey at six. He made a handy 37 off 25 balls in the quarter-final win against Yorkshire on Tuesday night.
Moeen Ali with another tidy over, costing just three and he has 1-33 from his eight overs so far.
Ten overs to go. What can Surrey post from here?
Surrey 259-4
Image source, Rex FeaturesFour, four and then out from Kumar Sangakkara in that John Hastings over. Big breakthrough for Worcestershire.
Sangakkara had earlier missed out on an attempted bouncer, but smashed the next ball down the ground for a flat-batted four. He then backed away from a short ball and deflected it down to third man for another four.
But, big bad John Wayne Hastings wins the battle as Sangakkara appears to glove a short ball down leg through to wicket-keeper Ben Cox with the diving catch.
