North Devon cricket twins Jamie and Craig Overton have extended their contracts at Somerset. The pair, who have both played for the England Lions team in the last year, have signed with the County Championship side for another three years. The 19-year-olds have both been involved regularly for Somerset since making their county debuts in 2012, with Jamie being selected for Englands One Day International squad for the series against Australia this summer. Somerset director of cricket Dave Nosworthy said: As a club we are extremely pleased to have secured these two young diamonds. Both Craig and Jamie are very highly rated nationally and as west-country lads we are excited to be able to help them develop and at the same time to have them performing on the field for us.
