Spring Baseball

Welcome to Spring! Spring Ball is BYB’s competitive season for all players in town. From Kindergarten beginners to 16 year-olds, our programs bring out the spirit of America’s pastime in everyone. Spring is the kickoff for an entire year of exciting baseball opportunities.

Practices begin in early April and games begin right after April break. For the AA League and higher, the “regular season” runs to late May or early June with playoffs thereafter.  All teams enter the playoffs and are seeded based on their season records.

These are high-demand programs at every level, and it's very important to register prior to this year's registration deadline. Everyone who registers before the Registration Deadline will be placed on a team. BYB places your child based on his or her grade, age, and/or skill level, as described below. In addition, we attempt to keep school friends together in the early years to the extent possible. Beginning in the AA League, team composition becomes more mixed in an effort to balance the teams as much as possible, and this also gives kids a chance to make friends from schools all over Brookline.
Eligibility for all of our programs is based on “League Age”.  The Little League age chart is available here


T-Ball - League Age 6 year olds

T-Ball is structured as a weekly clinic offered to all Kindergartners in Brookline. The program will be on Sunday mornings at Lawrence Playground, 10:00 am - noon, beginning April 24, running through June 13. Kids will work with experienced BYB coaches on very basic skills, with an emphasis on activity and fun. For more information, please contact .

Single A (A) League – League Age 7 and 8 year olds

The A League is for first graders of all abilities.  Our mission is to teach sound baseball fundamentals and a love of the game.  We use an innovative station-based practice format that emphasizes, fast pacing, learning and fun. New players will learn basic skills from the ground up. More experienced players will take their skills to the next level through advanced drill work and skill competitions. And everyone will have fun playing in fast moving split squad games.  

A League games are coach-pitch, with rules that have been modified for younger players. The games will use our new split squad format that limits each side to just 5-8 players. The result is fast moving games that fully engage young players. No scores or standings, just fun!  

Teams will meet twice each week on either a Tuesday-Sunday or Wednesday-Sunday schedule. Weekday sessions start at 5:30 PM. Sunday start times will vary week to week, between 1:00 and 6:00 PM.  All sessions (practices or games) are held at Lawrence and will last roughly 90 minutes. Opening day will be some time in mid April.

Double A (AA) League – League Age 8 and 9 year olds

AA League is the beginning of competitive baseball for kids. AA League baseball focuses on the development of necessary game skills, including pitching.  Scores are kept, and the “real games” are played.  The season will begin with the use of pitching machines in games.  Players will also participate in pitching drills and clinics and games will gradually integrate kid-pitch. Kids will be placed on teams based on coach evaluations and there is an emphasis on creating balanced teams of kids from different schools. Teams meet 3-4 times per week for games and practices throughout the spring. For more information, please contact the

Note: for 8 year olds with little or no baseball experience, joining the A League is an option. For more information, please contact the .

BYB’s programs for kids who have advanced past the AA League include AAA and Majors. Both leagues are competitive, with AAA being the first step toward the more competitive Majors league and eventually to big diamond baseball in Seniors. Placement is based upon evaluation (see “Tryouts,” below) and the Majors league utilizes a player draft.

AAA – League Age 10 to 12
AAA is a competitive league for players 10 and above where more advanced baseball skills are explored. Scores and standings are kept, teams are mixed from across Brookline, and many great friendships begin here. Coaches focus on specific position play, pitching effectiveness and hitting strategies. Three practices/games per week. Team composition favors parity between teams, and placement is at the discretion of the League organizer.
Note: for 9 year olds with exceptional skill, joining the AAA League is an option. Placement will be based on evaluation (see “Tryouts,” below) and availability. For more information, please contact the .

Majors – League Age 10 to 12
BYB’s most competitive league for players through age 12 (see “League Age,” below) who perform at the top of their game. This league features a limited number of spots and teams, with excellent strategic play opportunities for the serious player. Teams will have an equal number of players in each age group (12s, 11s, 10s) to the extent enrollment numbers allow. Teams have 12 players, up to 4 practices/games per week, and there are standings and playoffs. A tryout is mandatory for all players, including players who are returning to Majors for a second or third year (see “Tryouts,” below) and players are drafted by Majors coaches. Every effort will be made to place kids that are League Age 12 in Majors but only if they register by March 13 and come to tryouts. For more information, please contact .

At league age 13 players begin "Big Diamond" baseball. This challenging transition is exceptionally rewarding as players benefit from BYB's empahsis on skill development beginning at the earliest age. Strong fundamentals are essential for success on this larger scale.

Senior League - League Age 13 to 16
Seniors is open to all players 13 and older including those also rostered on a school or AAU team. Teams play on regulation 90-ft diamonds and finish the season with playoffs and a championship game.  Teams will play one game on Sundays and a game on Tuesday or Thursday during the week. There will aslo be a scheduled practice during the week. For more information, please contact the eniors organizer.

Brookline Bandits
For highly skilled players 13 and older players who desire a more competitive, travel baseball program with year-round activities, Brookline Bandists are part of the New England Elite Baseball League. Teams are formed in the fall and practice over the winter months. For more information, please contact .

BYB holds tryouts as a means of evaluating players prior to the Spring season. It is also an opportunity to get everyone together for a kickoff to a new year, and it’s a lot of fun. Please keep in mind that the tryouts are for team placement only, and not to exclude any player. Evaluators will be on hand to assess player’s skills, which will assist in creating teams with reasonable parity.

The tryout schedule is posted separately, usually on the home page.

Participation in the tryouts is mandatory for all players who wish to advance to Majors, including all players who are league age 12. A good performance is particularly important and we recommend advance preparation. All players league age 10 to 12 must tryout, including those who have already played on a Major A team. Players league age 13 or older must tryout only if they are in their first year in BYB.
