A council-owned baseball diamond at Unsworth Reserve, Caribbean Drive, in Unsworth Heights, Auckland, used by North Shore City Baseball Club. The club operates four council-owned diamonds each summer, and Unsworth Reserve is one of them. The website says the club runs a summer programme from October to April, with teams for all ages and abilities in Auckland Baseball competition and national tournaments. Off-season and schools programmes run from April to October, introducing new players and developing skills for experienced ones.
Reviewers say the field looks great after a recent upgrade, and that it can be used for baseball or football, with a good number of car parks, including disabled car parks. The club is an affiliate of Baseball New Zealand, and describes itself as all-volunteer, with values of service, hustle and respect. Players are told the club is one of Auckland's largest and fastest-growing baseball clubs.
