Season overview
Summer season at a glance
The club's philosophy emphasises that children should have a fun and positive experience – focusing on enjoyment rather than competitive pressure.
The highlight of the Tee-Ball season is the TBAWA Tee-Ball State Championships. Players can try out if they wish to pursue the sport more competitively and represent our club against top teams from around WA.
Season dates
Mid October (Term 4) through to March (Term 1), with a break over Christmas.
Rotating positions
Player positions and batting lineups are rotated weekly so every young Mariner experiences different roles.
State championships
The TBAWA Tee-Ball State Championships are held on the WA Labour Day long weekend in March.
