The following is a very brief description of each of the divisions offered by CSLL. Little League® has comprehensive resources on this topic if you wish to read their official take. This page is one such example: https://www.littleleague.org/play-little-league/baseball/divisions/  All divisions are open to any children from the ages of 4 to 13 years old.

Tee-ball
The Tee-ball division places a huge emphasis on fun. Instructional aspects of this division are fairly limited, with only the very basic fundamentals being covered. Run to first base after you hit it and throw to first base after fielding a grounder are about the maximum level of sophistication you'll see here. Games and practices rarely exceed an hour, and every kid gets to bat at least a couple times per game. Plan on two to three baseball events per week for this division (never more than three). Ages of 4 to 6. (To qualify to play in Cap-Soquel, player must turn 4 by April 30th.)

Single-A
In Single-A, we start to introduce "real baseball," but of course the emphasis is still on ensuring a fun, welcoming environment for players. Higher level instruction starts here, where we begin introducing mechanics of throwing safely and properly, and we start to develop hitting techniques. Explaining what a force play is might be learned at this level, too. This is a coach-pitch division, so hopefully the kids get some good pitches to hit!  Ages 6 to 8.

Double-A
This is the first level of baseball where the kids start to pitch to each other and stealing is allowed (at a pre-determined point of the season). You might see a double-play on occasion here, but as with all levels of play this is still highly instructional and there is a minimal focus on competition so don't put too much expectation on the players. There are no playoffs and standings are not kept.  Ages 7 to 10.

Triple-A
The Triple-A division could be considered to be the first competitive level of play, as game results are posted on our league website, the uniforms start to get a little nicer, the players start to develop their games at a much faster pace and have a little more expectation on them, and we now have playoffs. Winner of the playoffs gets to go on to the District 39 Tournament of Champions. Not to fear, though: this level is (and all levels are) still highly instructional, and the win/loss record doesn't have any bearing on the playoff seeding. Playing time regulations are enforced here, so all players will have the same minimum playing time per game, regardless of skill. A prerequisite for the division is a season of AA. Ages 8 to 11.

Majors
The Majors division is where you start to see a higher level of baseball play. You'll have players who are starting to develop physically, emotionally, and are attaining a higher baseball IQ than divisions below. Majors players will play in a continuous batting order on their teams, and get a very similar number of at bats. Majors players get nicer jerseys and hats, play in a very competitive playoff series, and the 12-year-old all-star team can make it all the way to the Little League World Series in Williamsport if they are good/lucky enough!  Ages 10 to 12.

Intermediate (50/70)
The Intermediate (50/70) Baseball Division is a program for 13-year-olds which utilizes a 50-foot pitching distance and 70-foot base paths. The division offers a transition for players between the standard Little League field size (46-foot pitching distance and 60-foot base paths) and the Junior/Senior field size (60-foot 6-inch pitching distance and 90-foot base paths). Many of the Junior League rules are used, such as runners being permitted to lead off bases, runners may attempt to steal at any time, and allowing an on-deck batter. Age 13.
