Despite losing Tammy Beaumont for eight, The Blaze maintained a healthy scoring rate against Surrey, thanks to Jones, Elwiss and Kathryn Bryce who made 56.
But the innings was also lit up by a full-length diving catch by keeper Kira Chathli to remove Sarah Bryce for 34, from the bowling of Alexa Stonehouse (2-65).
The Blaze total looked set to bring them a fifth win despite Danni Wyatt-Hodge’s 43 off 40 balls and 37 off 31 by Paige Scholfield, who put on 74 with Capsey for the third wicket.
Capsey, though, made the most of being dropped by Elwiss at deep mid-wicket on six and reached her century off 84 balls but had another escape before finally being caught at the start of the 46th over with 40 needed.
Stonehouse hit two sixes in an unbeaten 32 off 18 balls but number 11 Dani Gregory could only manage one of the two runs needed off the final ball as they finished on the same score as The Blaze, the second tie in the competition.
“With a big run chase today it was the perfect opportunity to bat and we all know that at Beckenham 350 is about par these days,” said Capsey.
“This is just the start of the county stuff, I can’t wait to see where it is in two or three years’ time. There’s also an element to it becoming more professional each year and the skill level getting higher and higher.”
At Edgbaston, on the day when she was selected for England’s first one-day squad under new head coach Charlotte Edwards, Lamb followed previous scores of 130 not out, 52, 86, 43, 20 and 74 by hitting a six and 10 fours to take her overall total to 493 runs.
She put on 116 with Katie Mack (57) and following a breathtaking slip catch by Katie George, who was initially wrongfooted by Seren Smale’s edge, Sophie Ecclestone, who was left out of Edwards’ squad as England manage her return from a knee injury, weighed in with 50 off 49 balls in her first game in the competition as Lancashire reached 276-8.
George top-scored with 35 in Warwickshire’s reply, but they were all out for 175 in the 48th over as Fi Morris recorded figures of 5-48.
“It was a really good all-round performance by the ream. I thought par on that pitch was 230 so we did really well to get up to 280,” said Morris.
“We’re five wins from seven now so we’re really happy with the start and to be among the leaders.”
