Vaughan, a top-order batter and offspinner, signed his first professional contract with Somerset earlier this season, having been part of the county’s academy set-up at Taunton since 2020.
Though he has yet to make his Somerset first-team debut, he made his mark at age-group level last week, with an innings of 85 from 83 balls for a Young Lions Invitational XI in a warm-up match against the England U19 ODI squad, for whom Flintoff top-scored with 106.
“They’ve helped me and given me more confidence in my leadership on and off the field, advising on bowling options and field placements,” Shaikh told Warwickshire’s website. “I like to think I’m a fairly calm guy and captaincy doesn’t faze me. I’m looking forward to the challenge and hopefully coming away with a series win.”
The team will also feature several players who have already been in ODI action against Sri Lanka, including Kesh Fonseka, Noah Thain, and Freddie McCann, who made a matchwinning 174 from 139 balls at Hove on Monday.
