The pilot for the 10U Yellow Ball Grand Prix Junior Circuit is a supplemental pathway for 10U players who have met the required play tracker points to advance to yellow ball play. The top 10 & Under Grand Prix point earners from the Yellow Ball Grand Prix will be invited to participate in an end of the season Early Development Camp.
