Jade Dernbach carries on and for the first time digs in a bouncer which Hamish Marshall plays well, keeping his eye on the ball and swaying out of the way. It is only Marshall's third game in the One-Day Cup this summer, but his experience could be crucial if Gloucestershire are to make a defendable total.

He is fortunate from the final delivery as the ball spoons up off the outside edge as he tries to play to leg, but falls well short of cover.

Gareth Roderick certainly wouldn't win any plaudits from cricket purists for his batting style, but it is effective enough, judging by his 334 runs in the earlier rounds of the One-Day Cup. 

He nudges a single into the leg-side before Hamish Marshall opens his account with a neat flick behind square for two.

Figures of 2-16 from his first five overs are good reward for Jade Dernbach. Hamish Marshall is content to block the final two deliveries, and Gloucestershire certainly need a major innings from the former New Zealand Test player.

A huge appeal from Jade Dernbach for a catch down the leg-side from Hamish Marshall's first delivery faced, but umpire Nick Cook rules there was not bat involved after the ball flies to wicketkeeper Gary Wilson.

Tom Curran has enjoyed a magnificent season in the Championship with 66 wickets. Can he produce a second breakthrough for Surrey? His hair scraped back into a chopped-off ponytail, the 20-year-old finds a good line and length straight away. 

Gloucestershire are lucky to escape from the final ball as a direct hit would have run out Roderick as he comes back fro a second.

Another good over by Jade Dernbach restricts Gloucestershire to just three runs. They will be content enough though at this stage. Time now for Tom Curran to replace his younger brother Sam.

Gloucestershire 29-1 (Dent 17, Roderick 11)published at 6 overs

6 overs

Sam Curran strays onto Chris Dent's pads and the ball is effortlessly flicked through square leg for a boundary. 

The left-hander hasn't managed a single fifty in the competition thus far - today would be a perfect day for him to come to the party, but the party is almost over when he checks a stroke later in the over and Curran spills a one-handed return catch.

To add insult to injury, Dent thumps the final delivery of the over through the covers for another four.

Jade Dernbach throws his arms in the air as a brave - but some might say positive - leave by Chris Dent sees the ball pass close to off stump. Gareth Roderick drives a delivery that is slightly overpitched, but doesn't time it perfectly and has to settle for one. 

It's a steady start by Gloucestershire, but hardly surprising after the shock of losing Michael Klinger in the opening over.

Chris Dent appears to have a habit of playing forward defensive strokes with his bat fractionally behind his front pad, which could make him a candidate for lbws, but when Sam Curran drops short, he cracks the ball away square off the back foot for four.

Curran responds with a beauty which just beats the outside edge, an excellent comeback by the highly-rated youngster. 

Chis Dent is squared up by the first ball of Jade Dernbach's second over, but the ball flies away for a single off the outside edge. A wide down the leg-side adds another run to the total, but that apart, it's a fine start by Dernbach, whose England career appears to be behind him at the age of 29. His last appearance was in a World T20 game against South Africa in March last year.

Who is the youngest cricketer to play in a Lord's final? There certainly can't have been many younger than Sam Curran, who is entrusted with the second over at the age of 17 years and 208 days. 

He doesn't have express pace, but is certainly nippy enough and finds early swing, but dropping short isn't a good tactic and Gareth Roderick puts him away for four.

After the shock of losing their captain, and leading batsman, to the third ball of the game, Gloucestershire get their first runs on the board as a thick edge by Gareth Roderick runs away for four to third man. The boys from Bristol are immediately on the back foot and need to regroup.
