Alex Hales has been included in an England ODI squad for the first time ahead of the upcoming series against India.
The Nottinghamshire opener, 25, has been on excellent recent form, with three hundreds in the last month.
He made 101 for England Lions against Sri Lanka A this month, as well as 141 in Nottinghamshire's victory over Middlesex in the Royal London One-Day Cup and 102 not out in the County Championship win against Northants on Monday.
The notable absentees include Essex all-rounder Ravi Bopara, who now appears unlikely to feature in the 2015 World Cup, and fast bowler Stuart Broad, who is set to undergo surgery on his knee.
Bopara is likely to feel aggrieved about the decision not to select him after a fine season for Essex, which has seen him score 121 runs in three Royal London One-Day Cup innings on top of the 417 he managed in the Natwest T20 Blast.
However, with bouncy, flat pitches expected in the 2015 World Cup, his medium pace bowling is unlikely to be used, and it appears that Ben Stokes, Moeen Ali and Chris Woakes are England's favoured all-rounders.
Tredwell, Gurney retain spots
With regard to England's other one-day specialists, James Tredwell has been picked despite spending the first-class season on loan at Sussex, and left-arm seamer Harry Gurney retains his spot after a solid series against Sri Lanka.
But there is no place for either Tim Bresnan or Michael Carberry, who are the other casualties from the Sri Lanka squad.
Middlesex's Steven Finn has returned to the England set-up in recent weeks in the Test squad, and despite not making an appearance, he has clearly impressed enough to be rewarded with a call-up.
He returned home early from the Ashes tour without playing a game to "work on technical aspects of his game".
However, he has taken 44 wickets at 29.72 apiece in 10 Championship games for Middlesex this season.
