New batsman Sam Curran, who was doing his A levels at the start of the summer, survives three Jeetan Patel deliveries but Warwickshire are absolutely on top now.

Oliver Hannon-Dalby will continue his spell, bowling to Rory Burns...

Zafar Ansari has made just one fifty in this competition this season and Surrey will certainly need him to make another today.

But Oliver Hannon-Dalby causes him trouble with his first ball, and Ansari nearly edges behind.

Hannon-Dalby has 2-13 off his first five overs. Not bad, that. 

Surrey's Rory Burns is living on ice as thin as many of my jokes.

Another big lbw appeal off Jeetan Patel's bowling but it was adjudged to be going down the legside.

Rory Burns is not having the best of times at the crease and there's a big appeal by Jeetan Patel, but he edged it onto his own pads. Then, in the final delivery of the over, the leaves it late to cut away for four.

By the way, we are told that the official competition mascot (see 11:00 entry) is called Gilbert. 

For anyone reading this aged under 20, look up the song Gilbert The Filbert on Youtube - it's one I'd like to see Bey or RiRi cover.    

Rory Burns has played and missed a couple of times today, and he does it twice in this Oliver Hannon-Dalby over.

The first one was an attempted drive which turned off the seam and the second was an attempted cut that he just missed.

Three runs from that over. This game is just ticking along, like a reliable old clock.

Oliver Hannon-Dalby, a nightmare for live text commentators if you need to type his name quickly, concedes four runs from his second over.

Warwickshire are only allowing singles at the moment on a cold day in London.

Off-spinner Jeetan Patel, Warwickshire's leading wicket-taker in the One-Day Cup with 20 this season, comes into the attack.

Division One's leading wicket-taker won't be terribly happy with Laurie Evans, though, whose misfield allows Surrey an easy two.

BBC Sport's Ged Scott at Lord's: "Interesting that at the end of the 20th over, Surrey should be only 82-2, after their flying start. After 5.2 overs, they were 40-0, but, stunned by the loss of their openers, it has taken them three times as long to double their score."

Oliver Hannon-Dalby is into the attack and starts off with a wide. What a way to begin in a final...

But just singles come from the rest of his over.

It's been a while since a boundary...

Huge appeal as Rory Burns misses an attempted reverse sweep off Ateeq Javid and it hits the batsman's pads.

But umpire Tim Robinson believes it was outside the line - and DRS would have backed him up on umpire's call.

Four singles from Chris Wright's most recent over. I'd still say that Warwickshire will be the happier of the two sides, but if Kumar Sangakkara can do what Kumar Sangakkara does, things could change pretty quickly.

Ateeq Javid back into the attack but he doesn't get a wicket this time - two runs from that over.

Jim Troughton was one of the stars of Warwickshire's B&H Cup final victory over Essex in 2002. Watching that game was his actor father David, who described the experience of watching his son in a Lord's final in a feature for a very different-looking, old school BBC Sport website.

Oh Jeetan Patel. The Warwickshire off-spinner totally misjudges a routine stop at mid-wicket, allowing Rory Burns' shot to skips right through his hands, like Bambi, for four.

Chris Wright is still looking the most dangerous of Warwickshire's seamers as his fifth delivery of the over just misses to outside edge of Burns' bat.

Ateeq Javid is rewarded for a wicket in his first over by being replaced in the attack by Chris Woakes...

Four runs from that over.

Judging the conditions at Lord's, it's overcast and they have the lights on.
