League Overview: Rookie builds on basic baseball knowledge by assigning positions, tracking defensive outs, and introducing some light competitive elements like keeping score and kid-pitch toward the end of the season. Rookie incorporates some elements of the Single A division, but it is played on an age-appropriate field (Kirby field at Marin Primary & Middle School).

• Goal/Style: Recreational with scorekeeping at the end of the season
• Team Formation: By league commissioner, honoring friend, school, grade, and coach requests where possible 
• Practices: One field practice per week + one batting practice per week (times chosen by coaches)  
• Games: One game per week, mostly Saturdays, with the occasional Sunday 
• Game Length: 4-6 innings 
• Inning length: First half of season: everyone bats. Second half of season: bases cleared if the defending team makes three defensive outs. 
• Pitches: Coaches from 30 ft, light introduction of kid-pitch toward the end of the season. Batters receive 8 good pitches, after which they sit, but there are no strikeouts. 
• Mound / Bases (ft): 30 ft Mound, 40 ft Bases  
• Umpires: None 
• Defenders: 10 defenders in position, some players may sit no more than one inning per game
