tourists won the third T20 by seven wickets at Derby.
England were bowled out for 116 in 19 overs after another impressive Sri Lankan performance in the field.
Chamari Athapaththu top-scored with 44 from 28 balls as Sri Lanka reached their target with three overs to spare.
It is only Sri Lanka’s second series victory from their last 15 bilateral series.
Athapaththu was dismissed by Alice Capsey with 52 runs still required but Harshitha Samarawickrama and Hasini Perera played sensibly to withstand England’s economical bowling to complete the chase.

It is England’s second successive batting collapse after their 104 all out in the second T20 at Chelmsford, with Heather Knight’s side looking fatigued and short of answers to Sri Lanka’s spinners.

They started poorly again and failed to recover as Danni Wyatt was caught at cover from the first ball of the game before Capsey was calamitously run out in the second over after a mix-up with Maia Bouchier, who went on to top score with 23.

Sri Lanka’s players were visibly emotional, running on to the pitch and embracing the batting pair as the winning runs were struck.
Meanwhile, England will look to fight back in the three-match one-day international series, which starts in Durham on Saturday.
A chastening night for England

England’s selection for this series has been a big talking point, the hosts missing some key players like Nat Sciver-Brunt and Sophia Dunkley, and Sophie Ecclestone and Lauren Bell later ruled out by injury and illness.

Sciver-Brunt, however, played domestic cricket for her regional side The Blaze last weekend, though she is expected to return for England in the 50-over format.
Players did need the rest – England’s Ashes summer was hectic, followed by a jam-packed Hundred in August, but despite missing that experience, England are not expected to lose to Sri Lanka.
England’s professionalism and strength in depth is far superior to their opponents, and there are still many experienced players in their squad – but it was their lack of clarity with the bat and repeated mistakes from the second T20 that should frustrate them.

They looked lost against spin, constantly opting for ambitious sweeps and reverse sweeps against the loopy slow bowling that Sri Lanka expertly used to tie them in knots.

Their most experienced duo of Knight and Amy Jones were tasked with steadying the ship – finding yourselves three wickets down with an inexperienced batting line-up can be forgiven.
The pair led a brief recovery with fourth-wicket stand of 29 but both succumbed to spinners again as the middle order lost three wickets for just two runs, leaving number seven Danielle Gibson to rescue England with a sprightly 21 from 15 balls.

England may not admit complacency, but in the selection, it appeared as if they underestimated their opposition.
It is also possible that after their summer, it may have been a series too far after the high of such a promising Ashes campaign.
But regardless of the reason, England’s next World Cup challenge comes in Bangladesh in 2024 and it would be no surprise to see opposition teams stacking their line-ups with spinners after the past two outings.(BBC Sport)
