Quote MessageIt's that question now as to whether or not it's a plus to have played the semi-final and already have a game under your belt, or whether you want to be the fresh South East Stars side.
Kalea Moore to share the new ball then with Alice Capsey as she opens from the Hotel End...
First three balls from Alice Capsey are driven straight back to her by Leah Dobson before the right-hander then lofts a drive over the infield for a couple.
It was in the air for a while and Stars were interested, but away in goes.
Bess Heath gets off the mark from the final ball with a full toss pulled into the legside.

The weather has certainly played ball for these finals, so fingers crossed the cricket matches it.

South East Stars v Northern Diamonds - play starts 16:00 BST
Image source, Rex FeaturesAt the opposite end of the age scale to Alice Capsey is 35-year-old former England all-rounder Jenny Gunn.
How many more big occasions she has left in her career remains to be seen, but as she showed in Diamonds' win over Southern Vipers earlier this afternoon, she still has plenty to offer any side.
She is their leading wicket-taker with 13 and her unbeaten 22 off 14 balls against the Vipers, including two final-over sixes, showed she has the power than can make a difference.
If Diamonds are to lift the trophy, it will be surprise if Gunn doesn't make a significant contribution at some point during the final.
South East Stars v Northern Diamonds - play starts 16:00 BST
Image source, Rex FeaturesAlice Capsey of South East Stars may be young, but she is certainly not afraid of responsibility.
Batting at number three in the order and opening the bowling, the 17-year-old was a key figure as they advanced to the Charlotte Edwards Cup final as group winners.
She contributed 163 runs, including an excellent 61 off 46 balls against Southern Vipers, and took seven wickets at a respectable economy rate of 5.35.
Capsey has already been a member of one Trophy-winning team this summer - with Oval Invincibles in The Hundred.

Player of the match Northern Diamonds batter Lauren Winfield-Hill:
"Winning the toss and batting first, we knew we'd have a good chance of getting in and posting a decent score.
"We felt if we could build partnerships, we would be able to hang in there and post a good score.
"We gave ourselves a chance and Jenny Gunn's big hits in the last over gave us the momentum.
"The bowlers then came along and backed that up for us."
Northern Diamonds beat Southern Vipers by 18 runs
Image source, Getty ImagesThat was a really excellent all-round performance by Northern Diamonds and so it will be the two group winners who contest the inaugural Charlotte Edwards Cup final.
One dropped catch apart, Hollie Armitage's side outplayed Southern Vipers in every aspect of the game.
And it was a result that will be even sweeter after they lost to the same opponents at Edgbaston in last year's 50-over Rachael Heyhoe Flint Trophy final.
Northern Diamonds 135-6 v Southern Vipers 117
So Vipers coach Charlotte Edwards won't be seeing her team lift the trophy that bears her name.
A disappointing run-chase comes to an end as Carla Rudd slogs a catch to Leah Dobson at deep mid-wicket and is out for five.
Jenny Gunn finished with 4-26, to go with her unbeaten 22 off 14 balls at the end of the Diamonds innings.
Star of the show, though, was England's Lauren Winfield-Hill with her composed innings of 65 off 49. It'll be South East Stars v Northern Diamonds in the final, starting at 16:00.
Vipers 114-9 v Diamonds
Ella Chandler tries to come back for two, but it's not even close as she is run out by Rachel Hopkins' throw. Will Vipers survive their 20 overs?

Quote MessageThere would need to be a major series of errors from Diamonds if they're not to make it to final from here.
Rudd 4, Chandler 1
A single to Ella Chandler, but Vipers need 25 from the final over.
Even six successive fours would only be good enough for a tie.

Quote MessageIt's one of those that either sticks or goes flying through the hands and on this occasion it sticks for Linsey Smith. Great moment.
