Announcing ABYB Spring 10U Travel Team for 2019!


For the 2019 spring season, ABYB will be offering a 10U travel team to augment the number of games played in our local league. This travel league will include teams from Concord, Stoneham, Bedford, etc., so some travel is required. All players born after May 1, 2008 (i.e., 10 years old or younger on April 30, 2008) are invited to try out for this team. Players MUST be registered for the 2019 ABYB spring season to qualify for tryouts. These travel games ARE NOT a replacement for local games. All players are required to play on their ABYB local teams.


•         After the tryouts, 11 or 12 players will be selected by the ABYB Player Agent (with ABYB Board approval) to be on this team’s roster.

•         The cost for this program is $275, in addition to the local spring registration fee.

•         The team will have off-season workouts at At-Bats for approximately 6-8 weeks.

•         Uniforms (hats and shirts) will be provided.

•         Tryouts will take place at AtBats (in early January – date TBD).


The team will be coached by Marc Antetomaso

  • Three time ISL All Star at St. Sebastian's School
  • Played Division I baseball at Seton Hall University
  • Has coached and organized numerous camps for the last twenty years


IMPORTANT NOTE: The ABYB Spring 10U Travel Team roster selection process has no connection to the summer Bay State and/or LLWS team selection process. Tryouts for those teams will still take place in May. Selection to this Spring travel team will have no impact on a players eligibility for the summer program teams.


To sign-up for the tryout*, users can get to it from our main Register Online page, or directly via http://assn.la/Reg/?r=1:254895


*only players registered for the 2019 ABYB Spring Season will be allowed to participate in tryouts. 2019 Spring registration will be open on December 15th.


If you have any questions please contact me at

ABYB: Parking Information

ABYB Families,

ABYB and other local sports organizations received this quoted information from Acton-Boxborough Community Education.  Please read and follow the guidelines included.

"The Acton Police Department will be stepping up its monitoring of all school areas and will be ticketing any cars found to be parked illegally.

Cars may not be parked:

1. anywhere there is a NO PARKING sign (not just during school hours but this is anytime of the day)

2. anywhere the curb is painted yellow, as this denotes a no parking zone.

3. on any sidewalk

Only cars with handicapped accessible placards may park in handicapped parking spaces.  Nor can you park BETWEEN two handicapped spots.

If you have any questions, I recommend you contact the Acton Police Department."

At some fields, parking areas are obvious, however please note:

McCarthy-Towne field is a specific point of concern.  We have been informed that the entry road to the Parker Damon building can be considered a fire lane (I had been warned personally by the APD when I coached Minor C), and parking along the curb on this road can therefore be considered a violation.  Additionally, parking half on the sidewalk is illegal.  Please park in lined spaces in the parking lot.

Douglas School field is on Elm Street, and posted signs indicate no parking is allowed on Elm Street.  APD enforces this in routine patrols for both the t-ball field and the basketball courts.  Park in lined spaces in the Douglas school lot or park at the Elm Street tennis courts.

Holiday Inn parking is in the Holiday Inn lot in lined spaces.  Even if you can find the entrance to the dirt access road used by the mowing crew, no parking on the field is allowed during ABYB events.

Hart Field and MacPherson Field visitors should park in the lined spaces in the Conant school lot.  The dirt roads leading to the fields are for emergency vehicles.

Veterans Field visitors may find the parking lot crowded when two games are on simultaneously.  Overflow parking along Route 27 is questionable: at times cars have been ticketed and we do not have clear resolution from APD.  It is safer to park across the intersection in the CVS plaza and use the crosswalks to return to the field.

High School 1 & 2 visitors must park in legal spaces.  After school hours, marked faculty spaces are available to all parkers, but illegal spaces, yellow curb parking, and handicap parking are still enforced.

Hopefully the information above is clear.  Feel free to email me with any questions and I will try to seek clarification from the Acton or Boxborough Police Departments if necessary.

Thanks for your compliance!

ABYB Fields Coordinator

Update on bat rule for Babe Ruth baseball

ABYB Babe Ruth teams participate in the Minuteman Baseball League.  The following bat rules (taken from the www.mmbrl.com web site) are adhered to:

5.4  The MIAA rules on the use of non-wood bats shall apply to all Minuteman Baseball League players (Patriot, Minuteman, Summer, etc.). All bats not made of a single piece of wood  shall meet the Batted Ball Coefficient of Restitution (BBCOR) performance standard (reference NFHS Rules 1-3-2 through 1-3-5), and such bats shall be labeled with a silkscreen or other permanent certification mark. Each manager will be responsible for enforcement of this rule among his/her players. The penalty for illegal bat use will be as follows:

5.4.1     If the illegal bat is identified and replaced before an at-bat has concluded, there is no penalty.

5.4.2     If the illegal bat is identified after an at-bat has concluded but before a pitch has been thrown to the following batter, the batter using the illegal bat shall be declared out, and all baserunners shall be returned to the bases they occupied prior to the final pitch.

5.4.3     If the illegal bat is identified after the at-bat has concluded and after a pitch has been thrown to the following batter, the result of the at-bat stands.


ABYB Note: As of Fall 2014, in ABYB's internal fall Babe Ruth league, 13-yr-old players are allowed to use bats with at most a -7 length to weight difference (“Drop 7”).  In the spring and summer, Minuteman rules allow only a Drop 3 bat, regardless of age.

ABYB Vision and Mission Statement
At the November 2010 ABYB Board meeting the Board voted unanimously to approve the proposed ABYB Vision and Mission developed by a subgroup of the Board.  The following vision and mission statements were approved:
Vision Statement
To be recognized and respected as the leading youth sports organization in Acton and Boxborough.
Mission Statement
  • ABYB is a parent and volunteer organization committed to building an appreciation for the game of baseball through quality coaching and parental support & involvement.
  • ABYB will strive to offer high quality baseball throughout the entire ABYB program.
    • It is the objective of the ABYB program to create an environment that is safe, provides an opportunity for all players from T-Ball through the Majors and Babe Ruth divisions to develop skills and game knowledge, allows all players to experience the success they are capable of achieving, and teaches the life-long lessons of sportsmanship, teamwork, fair play, and respect for others.
    • ABYB’s spring T-Ball through Babe Ruth programs provides an opportunity for players to develop skills in a competitive environment whereas the fall programs focus on development in a less competitive environment.
    • ABYB offers summer all-star programs.  These programs provide an opportunity to experience the best coaching available and maximize player potential, in a competitive, inter-town environment.
    • ABYB offers summer intermediate programs for players who wish to play baseball in a less competitive inter-town environment.
  • It is the responsibility of all ABYB League officials, including the Board of Directors, coaches, umpires and parent volunteers, to understand and fulfill these objectives.
“These are truly exciting times for ABYB.  These guiding principles will help make ABYB the leading youth sports organization in Acton and Boxborough”, said Sanjay Khosla, President of ABYB.  “Over the next several months the Board will be taking initial steps towards further developing existing programs and establishing new ones to achieve our vision.  We look forward to the support and involvement of ABYB players, parents and coaches,” said Khosla. 
If you have any questions or comments regarding the new Vision and/or Mission statement please don’t hesitate to inquire.  Further, if you are interested in serving on the ABYB Board please let us know.  Several positions are available.
