minor and major league divisions COMPARISON

What is the difference in game structure between the Minor and Major League Divisions?

  • Minor League: Games last 1 hour or 2 innings, whichever comes first. (subject to change)

  • Major League: Games last 75 minutes or 3 innings, whichever comes first. (subject to change)

 

How is batting handled in each division?

  • Minor League: Every player bats once per inning, with no strikeouts, walks, or outs. Players may use a tee if needed.

  • Major League: Each player bats once per inning, with up to 12 pitches per at-bat. If the player doesn’t hit after 12 pitches, they use a tee. Strikeouts and walks are not allowed. Players can get out.

 

Are there differences in base running?

  • Minor League: Players advance base-to-base after each hit, with the last batter running all bases for a home run. Overthrows do not impact play.

  • Major League: Players must stop advancing once the ball is in the infield or controlled by an outfielder, but cannot advance on overthrows or tag-ups.

 

How do defensive positions differ?

  • Minor League: There are no defensive positions. Often times, a player and their MVP will play catch in the outfield while the other team is up to bat.

  • Major League: Defensive players must remain in assigned positions, and rotation is required to ensure equal playtime. A maximum of 12 defensive players (6 infielders and 6 outfielders) are allowed (See defensive position chart for more information).

 

Are outs recorded in each division?

  • Minor League: Outs are not recorded, ensuring all players get to bat and score.

  • Major League: Outs are recorded, but the inning ends only when the batting team completes its lineup.

 

What equipment is used in each division?

  • Minor League: Only plastic or foam bats are allowed for safety.

  • Major League: Plastic, foam, metal, and wood bats are allowed. Helmets are required for all players in the batter’s box, on base, or in the on-deck circle.

 

What teaching moments are provided?

  • Both Divisions: Coaches are encouraged to use game pauses to explain rules or clarify calls for players.

 

Do both divisions have support systems on the field?

  • Minor League: Each athlete is paired with a Most Valuable Partner (MVP) for encouragement and assistance on the field. If a MVP is not available, coaches will encourage parents to join them on the field.

  • Major League: Independence is encouraged on the field. There are no MVPs to assist them. They lean on teammates and coaches for guidance and skill development.

 

Is there an age limit for Casey's Clubhouse?

  • Minor League: A player must be 5 years old by the start of the first day of the season. There is no age cap.

  • Major League: A player must be 16 years old by the start of the first day of the season. There is no age cap. A player must have played at least one year in the Minor League Division before being evaluated for the Major League Division.

 

What is the same across both divisions?

  • Focus on Fun and Inclusivity: Both divisions prioritize enjoyment, learning, and relationship-building over the outcome of the game.

  • Participation for All: Every player bats in each inning to ensure the players get to hit 3 times per game, and all games emphasize camaraderie over competition.

  • Emphasis on Teamwork: Players cheer for their teammates and celebrate everyone’s efforts, promoting a positive and supportive environment.
