2019-2020 Team Formation & Schedules

All of those participating in our house league this season will hear from their respective coach on/about Halloween. Over the next several weeks we will be conducting our process to form teams and create schedules. Please wait until after October 31st to contact the league if you have not yet heard from your child's coach.

Practices will begin on November 11th.

First Games will be played December 7th.

Requests to play on a certain team or with other players in the same age group are not able to be accommodated. We use the data collected during our evaluation process to conduct our draft process and distribute skill and ability as equally as possible across the age group.

Player Evaluation Process

Player Evaluations will occur on the following weekends (all division are based on GRADE the player is in school):

  • Boys 6, Boys 7 and Boys 8, Girls 5/6th and Girls 7/8th Grade Division will occur on September 21 and 22nd. 
  • Boys 3, Boys 4, Boys 5 and Girls 3/4th Grade Divisions will occur on September 28th and 29th.

Our Evaluation Schedule will be published in early September. All Evaluations will take place at the Play To Win Athletic Center located at 44600 Guilford Drive Suite 100 Ashburn VA 20147. Player MUST evaluate with their gender and grade level. 

Players who are on the WAITLIST - you will be notified by (approximately) September 15th if a spot becomes available. Those that are on the waitlist - whether they played travel last year or not - are not eligible (due to league insurance requirements) to participate in our player evals or middle school team tryouts until they are fully registered. 

Players intending to tryout for their middle school team MUST first complete the player evaluation. As found below, players who rank in the top 1/3 of their grade level will then be invited to attend the middle school tryouts which will be held at the end of September/beginning of October.

  • Tryouts for the middle school teams will occur between September 29th and October 6th.

For those that tryout for the middle school team, are not selected and wish to withdraw will be afforded a refund less a $50 fee due to the costs we as a league incur during the evaluation process performed by a 3rd party assessor.

Those that withdraw must do so by October 9th, 2019 by email the league at

Practice begin on/about November 11th and conclude on/about March 15th.

We will play games on January 20th and February 17th-- all of which tend to fall around winter break for LCPS and long weekend holidays. Requests to move games to alternate dates are not feasible.

Exact practice times/locations will be communicated once teams are formed by October 31st.

Please ensure to read our FAQs and League Rules posted on the website. Those who volunteer as HEAD coaches, we will make every effort to keep those individuals close to home for their practice location - we do not guarantee the same for the over 1900 players in the league.

Please note that those in Grade 5th, 6th, 7th and 8th may have later end times (approx 930pm) for practice. We make every effort to have as many of the younger grade levels end around 8pm but it is contingent on gym allocation from Loudoun PRCS.

Registration System Now Closed

The registration system will open on Thursday August 15th - at this time we will fill any and all available space that remains. The fee does increase for those registering between August 15th and September 8th. Some divisions have already reached their capacity and we will be taking wait list additions at that time. Should your child be placed on our wait list; they are not yet registered with the league will NOT be eligible to participate in evaluations, middle school (travel) team tryouts, or take part in any AYBL activity. As a league we operate on a first come first served basis. The number of players we are able to support is driven largely by 2 factors --- the main one the number of HEAD coaches; without head coaches we are unable to add additional teams and players. While many folks offer to assist each season, an assistant coach does not carry the same level of commitment needed for us to assign players or form additional teams; only head coaches move that needle. The second factor is gym space for practices - we are limited to the facilities within the county that are made available via PRCS on any given night. There is a finite number of kids we can have practice at any one time before it becomes a safety issue.

Our registration period has now ended. Those players currently on the wait list will be notified if there is a spot available over the next 5-7 days (approximately).


Answer to a few of the most common questions are below...

  • All registration is FIRST COME, FIRST SERVED until the league is full. Our age groups are capped based on the prior years history AND the number of registered HEAD coaches. The more HEAD coaches we have, the more kids we can support. Again, our numbers are determined based on the quantity of HEAD coaches we have in each age group.
  • All registrations are based on the current GRADE the player is in school for the 2019-2020 school year.
  • The Registration below is for the WINTER 2019-2020 Season - we do not have a spring or summer season. Once you register, you will likely not hear from the league until sometime in August or September as we get closer to player evaluations.
  • All Registration is done online via a credit card - there is no in person registration and we do not accept checks. Due to the rising costs associated with uniforms, game officials and insurance premiums; this years fee will increase by $5 per player resulting in $170 per player (+$25 fundraising fee which eliminates the exchange of cash associated with our annual raffle at our season tip off) for all age groups before any multi-player discounts are factored in. All multi-player discounts MUST occur within the same transaction meaning you need to register all of your children within the same "shopping cart" to receive the discount. Requests to issue the "multi-player" discount after the fact will not be processed.
  • If you wish to have your child "play up" you must contact the league PRIOR TO registering them so that we can approve and adjust their age in the system
  • Those wishing to represent their middle school in the county wide PRCS Middle School League...MUST be registered with AYBL in order to participate in evaluations and tryouts
  • Financial assistance is available, please contact the league for details.
  • Teams are formed based on player evaluation data -- we do NOT take into account where a player lives and where they might practice. may live in Brambleton and could be drafted to a team that practices in Lansdowne or vice versa. Requests to change teams due to practice location will not be granted. FURTHER, we are not able to accommodate requests for carpools or grouping neighbors on the same team.  All teams are formed based on the data collected during player evaluations.
  • Players in Elementary School grades typically (90% of the time) practice between 630 & 9pm; players in Grades 6-8th typically practice after 8pm. Due to gym space availability - players in the 8th grade could practice between 830-1015pm.
