Captain Heather Knight hints England will continue to rotate squad in T20 series against Sri Lanka

England started the three-match series with a 12-run win at Hove on Thursday with teenagers Alice Capsey, Freya Kemp and Mahika Gaur all impressing during the rain-affected victory.

Sophia Dunkley and Nat Sciver-Brunt were rested for the series while Sophie Ecclestone is injured, which means this is an experimental England group and uncapped Bess Heath could be the next youngster in line for a debut ahead of Saturday's clash at Chelmsford.

Knight said: "We want to give people an opportunity and it is obviously finding the right time to do that. You also want to find pockets in games where you will use different people.

"We have a number of players to choose from, which is really nice and hopefully the main outcome of the series will be giving experience to those players and having a little look at a few players who haven’t been involved.

"It is exciting isn’t it? It tests you as a captain as well because plans change and you get used to new players which helps keep things nice and fresh."

A new-look England XI were able to impress with the bat in Sussex, posting 186 for four from 17 overs with Danni Wyatt hitting 48 and Capsey blitzing a 27-ball innings of 51.

Maia Bouchier (22) and Kemp (20) made the most of their opportunities before debutant Gaur caught the eye with the ball.

Gaur, 17, claimed one for 16 from her two overs, which were bowled at the death after rain at Hove provided Sri Lanka with a new Duckworth-Lewis target of 68 from six overs.

The tourists were eventually restricted to 55 for three and Knight's side will now aim to wrap up the series in the second IT20 on Saturday, which begins at 2.30pm.

"It tested our adaptability at the end, tough conditions with the ball, but really pleased," Knight told Sky Sports.

"We were put under a bit of pressure at the end, which I quite liked and I thought Mahika was brilliant on debut.

"You don't normally get that height, particularly from a left-armer, in women's cricket and the fact she swings the ball late is a really impressive skill.

"She had to change her role a little after the rain break and bowl her death stuff, but we were really pleased and now look forward to Chelmsford."
