Hello Killingworth Players and Parents!

We would like to talk to you today about a very serious matter. One that might be summed up as an epidemic here in the Northeast. It's something that is dark, cold, and makes is hard for children to go outside. We are talking about...WINTER!

Every year the temperature drops, the days shorten, and children are forced to play inside. I'm sure you are thinking "What can I do? How can we stop this?"

Here at KYL we have done extensive research and we have found a way to combat this very serious problem. Our data shows conclusively that there is a direct correlation between the number of children signed up for baseball/softball and the temperature. In fact for every child that signs up, not only does the temperature rise over time, but the days actually get longer. 

So please do your part to wipe out another long winter and help usher in a bright and warm spring!

Register your child here:

Thank you, and see you on the field!

2018 Bat Standards

2018 Baseball Bat Standard: What You Need to Know

Click here for a video

Starting on January 1, 2018, the new USA Baseball Standard will be implemented across all Little League baseball divisions and Little League‐approved bats will no longer be acceptable for use in any Little League game or activity. More details, as they become available, will be provided below.

Testing and evaluating of youth baseball bats has evolved into a science. So much so that the standard has also evolved to where USA Baseball, the national governing body for the sport of baseball in the United States, is adopting a new method for measuring bat performance in the testing of youth bats that will go into effect on January 1, 2018. The new USA Baseball bat standard (USABat), was developed by a USA Baseball committee of scientific experts. 

Effective on January 1, 2018, Little League Baseball® will adhere to the new USABat standard. No bats previously approved for use in Little League Play (Junior League Baseball and below) will be permitted to be used in any Little League game or practice, or other Little League function, event, or activity. 

What this means for local Little Leagues, and Little League baseball players in the Tee Ball through Junior League Divisions, as well as Little League Challenger Division®, is that all current Little League-approved bats can be used during the 2017 Little League regular season and throughout tournament play, but can no longer be used starting in 2018. All of Little League’s current bat regulations will remain in effect until December 31, 2017. Be aware that this new bat standard effects Little League Baseball only. There are no changes to the bat standard or regulations for Little League Softball®.
