The Mariners B team have always been competitive drawing on the clubs reserves of youth players. They have won the league championship in 2007, 2012, 2019, finishing runners up in 2020 and winning again in 2021.  

This group caters for the 13-15 year olds. This is the last stepping stone towards playing in the senior league in Ireland. They train and compete with hard balls, and the distances they play from, although not quite adult length, are not far off. Some of the stronger cadets can sometimes be asked up to play up to senior level games if needed.

The Mariners little league is the strength of the club with many former and current adult players progressing from this age group.

This team is for ages 9-12 and trains with the Coach Pitch team. There are several games scheduled throughout the season. The season runs from April –September. 

This team is for ages 6-8 and trains with the Little League team. Games are regularly scheduled with other clubs. The season runs from April –September.
