  • Registration will open December 1st (and will close in mid-February).   On December 1st there will be a link on this page for you to register.  So check back.  If you need a reminder on MTYAA age rules, here is an MTYAA Age Timeline.

  • Hey Coach - If you want to coach, please fill out the Coaching Application as soon as possible (even if you are a returning coach).  This allows us to do background checks and it helps our directors plan their leagues.

  • New Bat Rules - All national youth baseball organizations will be changing their bat safety standards starting January 1, 2018.  See the following link for details and an approved bat list: NEW BAT RULES

  • New League Age Rules - In 2016, PONY national adjusted the league age to be the child's age on August 31st instead of April 30th.  In recent years, MTYAA has grandfathered in the old rule and allowed kids born between April 30th and August 31st to choose whether to play up or down.  Starting in 2019, MTYAA official league age will match the PONY national rules.  For 2018, we strongly encourage parents to register their kids according to the national rules but will still honor our old rules for this one last year.  For more details on the national age rules and to see an age chart, see here: PONY NATIONAL AGE RULES AND AGE CHART

Please allow us to introduce you to the league.

The primary features that distinguish Pony baseball from Little League baseball are those of a two year age bracket system and scaled diamonds. Additionally, PONY teaches lead offs and base stealing starting at age 9 (Mustang Division), or earlier while pitchers learn pick off moves and holding runners on base to counter the potential steal. 

The scaling of the base paths, pitching distances and location of the outfield fences are proportional to the physical abilities of different age groups.



Practices start the beginning of March and games begin in April. Season ends mid-June.

Practices and games are held at fields rented through the City of Brier and Mountlake Terrace. 



Age 4, 5 or 6 on April 30. The Shetland division is the first baseball experience for most of its participants. Focus on basic instructions of the game to beginning players. Players are encouraged to have fun. The playing field is 50 ft. base paths with batting from a Tee or hit from coach-pitch.


Age 7 and 8 on April 30. The Pinto division expands the player’s skills by learning basic fundamentals of baseballs and rules of the game are taught. The playing field is 50 ft. base paths with coach pitch.


Age 9 and 10 on April 30. The Mustang division is a start to the players’ training in the complete game of baseball featuring lead-offs, pick-offs, and balks. Players go into a draft to allow for even skilled teams. The playing field is 60 ft. base paths with a pitching distance of 44 ft. 


Age 11 and 12 on April 30.  The Bronco division takes the developed young players into the full game of baseball, with no restrictions on base stealing or runs allowed. The scaled fields allow kids to develop skills gradually and not feeling defeated by the size of the field. The playing field is 70 ft. base paths with a pitching distance of 48 ft. 


Age 13 and 14 on April 30, 2014.  This division is divided into two sub-divisions, Cascade (recreational) and Olympic (select). Both division play inter-league schedules which require some travel for games. The playing field is 80 ft. base paths with a pitching distance of 54 ft. 


Age 15 and 16 on April 30.


Age 17, 18 and 19 on April 30. The Palomino division is the highest division of the program.


All ages welcome.  This division is for players with special needs.  The division is open to any student in the Edmonds school district with an IEP.  All ages practice and play together and while basic baseball rules are followed like base running, most rules are heavily modified based on the needs of the player.  Games are played with other leagues and with teams from other divisions in our league.  Practices and games at this division focus on team building and we do not allow rules to get in the way.
