In the Spring season, ABYB runs the following divisions:
T-Ball, for Kindergarten-aged players and pre-K players meeting a minimum age requirement
Minor C, for first-grade players
Minor B, for second-grade and some third-grade players
Minor A, for some third-grade, all fourth-grade, and some fifth-grade players
Majors, for some fifth-grade, all sixth-grade (unless they turn 13 before 9/1)
Babe Ruth 13-15's, for players aged 13 to 15 (two 16-yr-olds will be allowed per team, however they may not be playing High School or AAU baseball and will have significant pitching limitations)
If offered by the Minuteman League, there is the possibility of a Babe Ruth 13’s-only division, strictly for players aged 13 moving to the big diamond for the first time. (This depends on registration numbers across the participating towns)
The following age-based exceptions are based on ABYB and Little League Rules. This applies to the Spring 2020 season.
Players must be born on or before 8/31/2015.
The oldest date of birth for Majors is 9/1/2007 (independent of grade).
6th grade players who turn 13 before 9/1/2007 can register for Babe Ruth (90-foot diamond).
The oldest date of birth for the 13-15's Babe Ruth division is technically 5/1/2004, however each team is allowed up to two players who are 16 as long as they were born on or after 5/1/2003. Those 16-year-old players with a birthday between 5/1/2003 and 4/30/2004 have significant restrictions on pitching eligibility.
Costs for the Spring league vary by division:
T-Ball and Minor C: $145 per player
Minor B, Minor A, Majors and Babe Ruth: $165 per player
You can receive a $10 early-bird discount if you register by January 21st.
A $15 non-refundable late-fee will be added if you register after February 28th.
Families registering more than one player pay a maximum of $250 (not including late fees).
ABYB offers secure online credit card transactions using Visa, American Express, MasterCard, and Discover.

The withdrawal deadlines for Spring 2020 are:
T-Ball, Minor C – April 4th

An exception will be made for a player who registers for ABYB and subsequently makes a school team and then wishes to withdraw from ABYB, since school team tryouts may not occur before March 21st
