England have promoted Jamie Smith to open the batting in Harry Brook’s first one-day international since being appointed full-time white-ball captain.
Smith will open alongside Ben Duckett against West Indies at Edgbaston on Thursday.
Former captain Jos Buttler and all-rounders Jacob Bethell and Will Jacks are in the side after returning from the Indian Premier League (IPL).
Smith, who batted at number three during England’s dismal Champions Trophy campaign this year, has never opened in List A cricket.
Brook, 26, said he and coach Brendon McCullum had a hunch that Smith, who bats at seven and keeps wicket for the Test side, could be an “amazing” white-ball opener.
“He’s got the strength to do so – the technique to be able to face the swinging ball,” Brook told BBC Sport.
“As we’ve seen in Test cricket, he’s a very good player. He can put their best balls under pressure from any position.”
Smith has opened in first-class and T20 cricket. In three innings at number three in the Champions Trophy, he averaged only eight.
Surrey’s Jacks, a regular white-ball opener, would have been another option at the top of the order. He is instead listed at seven, one place behind fellow spin-bowling all-rounder Bethell.
They are followed by Jamie Overton and Brydon Carse, fast bowlers who are more than handy with the bat.
Pace bowlers Jofra Archer, Mark Wood and Gus Atkinson are missing because of injuries.
Overton as one of three frontline seamers is a potential concern, but England look to have more bowling options and greater batting depth than at the Champions Trophy.
