Irvine Ranch Little League is divided into nine divisions within two divisional groups.  Depending on player enrollment for any given season, the league may combine divisions to create adequate team size and number of teams per division.  As an example, we may combine Rookie & A Ball to create enough teams to form the division.  The registration numbers and player safety will be the basis for combining divisions.  Fall ball allows players the opportunity to self-select the next division of play prior to the Spring regular season, assuming their participation in that division does not pose a safety risk.  The level of play in Fall Ball does not guarantee the level of play for the Spring season.  During the spring season, all players in competitive (upper) divisions are subject to the results of the player evaluation and draft to place them in a division that is appropriate to their skill level.

LOWER DIVISIONS - developmental playing divisions with a focus on core skill development.  Game results are not recorded, nor are divisional standings kept.

• Ice Cream Division - the division is structured for players between the league ages of 3 ½ to 4 years old who have not played organized baseball.  There is a heavy focus on core baseball skill instruction and providing the players a fun environment to learn the game.
