England have named five uncapped players in their 16-man squad for three T20s against South Africa at the end of June. Liam Livingstone and Mason Crane have won first call-ups, while Dawid Malan, Tom Curran and Craig Overton are also included ahead of potential debuts.
Joe Root is among several white-ball regulars rested for the T20 series, meaning he can play Championship cricket for Yorkshire ahead of his first Test as England captain in July. Moeen Ali, Adil Rashid, Jake Ball and Ben Stokes have also been released to their counties, while Tymal Mills is missing through injury.
Mark Wood will only be available for the first match of the South Africa series, with his workload likely to be managed by England after a starring role in their run to the Champions Trophy semi-finals. For the final two matches, his place will be taken by Somerset's Craig Overton - who was previously called into the ODI squad in 2015, alongside his twin Jamie, but did not play. Jonny Bairstow is included for the first two matches before returning to Yorkshire.
The inaugural round of day-night Championship matches on June 26-29 will see the involvement of Root, Moeen, Rashid, Ball, Stokes, Wood and Bairstow, as well as former England captain Alastair Cook and fast bowlers Stuart Broad and James Anderson, who is expected to have recovered from a groin injury.
Livingstone had been tipped for inclusion in England's one-day squad at the start of the summer and has been in impressive form for Lancashire and the Lions. "I found out yesterday and it's obviously a very nice moment for me and I'm really looking forward to next week," he said.
"I've really enjoyed my time with the Lions whenever I've been involved. You're given a lot of freedom and a free role to play. It's a great environment to be involved in and especially with the way I play my cricket, it's very exciting ... I've always tried to not change how I am or the way I play so I'll just go in and try to do what I've done for Lancashire.
"From the very first day of hitting a cricket ball, it's what you want to do and it's what you work hard to achieve. A lot of hard work has gone into it, so if I was to make my debut it would be a very special moment for me and my family."
Crane, the Hampshire legspinner, made headlines when selected as an overseas player for New South Wales during the winter and was among the leading wicket-takers in the group stage of the Royal London Cup with 14 at 27.42. Malan, 29, is a former captain of Middlesex's T20 side and was a non-playing member of the squad for the one-off T20 against Sri Lanka last year, while Surrey seamer Curran won his maiden England call-up to the ODI squad on the tour of the Caribbean in March.
"The T20 series against South Africa presents us with an opportunity to incorporate several players who have come through the talent pathway into the senior group," James Whitaker, England's national selector, said. "The squad has an exciting blend of youth and experience and we are looking forward to a competitive series against strong opposition.
"With five uncapped players selected, there is undoubted talent coming through the system and we are excited to see some of these players showcase their skills at the highest level.
"Liam Livingstone, Dawid Malan, Tom Curran and Craig Overton have impressed for the England Lions over the past 12 months and have transferred their skills across all formats, in particular with their respective counties.
"Young legspinner Mason Crane is another player with great promise and he has made great strides with Hampshire this season and has added to his experience with stints in the North-South Series earlier in the season, where he took crucial wickets and even earned selection for New South Wales in Australia's premier domestic competition the Sheffield Shield."
