CIYMS captured the senior cup last year and narrowly missed out on the league title as well. They have a relatively settled squad and the return of James Cameron-Dow will be a huge boost.
"James Cameron-Dow (JCD) returning after his previous stint with us in 2015, he will undoubtedly add some additional firepower to a strong and settled squad," said captain Nigel Jones.
"He also brings a positive and lively energy with him which we are looking forward to welcoming back to the club.
"Matt McGillivray our Pro in 2017 returns for another stint - we feel very fortunate to have him returning, his performances and professionalism spoke for itself last season and I know he is keen for us to challenge on all fronts this coming season.
"I'm looking forward to continue to support (as skipper and at training) both John Matchett and David Robinson's development this season and believe they are both starting to feel at home in their respective roles within the team - John was brilliant for us last season at the top of the order getting us off to a positive start and played some key innings throughout the season.
"David continues to learn and grow in confidence season by season and has an important role in breaking partnerships which he has also done now on a number of occasions over the past couple of seasons.
"2018 for us will be about playing as a unit, taking the opportunities when they present themselves and only concerning ourselves with the game at hand - if we can manage that then we'll not go too far wrong!"
