Mercer Island Little League: Baseball News

Big Diamond Baseball (13 and Older)


Seniors is a level of Little League for 13-16 year olds.  Seniors baseball plays on a full size baseball diamond (60’6’’ pitching rubber, 90’ bases).  As with other levels of Little League, players are eligible to compete in end-of-the-season tournaments and All-Stars.  13-14 year-olds are eligible for Seniors baseball, but players are encouraged to participate in either Intermediate or Juniors.



Juniors is a level of Little League for 13-14 year olds.   Like Seniors, basepaths are 90’ and the pitching distance is 60’6’’.  As with other levels of Little League, players are eligible to compete in end-of-the-season tournaments and All-Stars.  The only real difference with Seniors is the age of the players.  13 year olds are eligible for Juniors, but are encouraged to participate in Intermediate if possible.



Intermediate is Little League’s newest level.  It is to be used as a stepping stone between the traditional Little League Diamond and a full size diamond used in Juniors and Seniors.  Basepaths are 70’ and pitchers throw from 50 feet.  It is for League Age 13 year olds (11 and 12 year-olds are eligible but MILL encourages 11s and 12s to play in Majors or Coast).


**Notes about Seniors, Juniors and Intermediate:  Mercer Island teams interlock their schedule with other teams in our District.  Half of the games will be played on Mercer Island and the other half off Island.  Game days also vary.  There is not a set schedule like there is in our Player Pitch baseball leagues.


Additionally, it is not guaranteed that we will have enough players to field teams at all levels.  If we are unable to field our own team, there is the option to combine with other leagues.  Those decisions won’t be made until late February or early March.


Player Pitch Baseball

Majors Baseball 10-12 Yrs. Old
Majors is the most competitive division of Little League.  It includes all League Age 12 year-olds, strong 11 year-olds and outstanding 10 year-olds.  Majors focuses on advanced skill development and play beyond age 12.  Players will be drafted onto Majors teams based on ability.  Majors teams will practice twice a week, and play one Wednesday and one Saturday game.


Coast Baseball 9-11 Yrs. Old
Coast is intermediate player pitch baseball, primarily for 10 and 11 year-old players, as well as some highly skilled 9 year-olds.  Coast teams will practice twice a week, and play one Thursday game and one Saturday game.


“AAA” Baseball 8-10 Yrs. Old
“AAA” Baseball is entry-level player pitch baseball, for 9 and 10 year-old players, as well as a few highly skilled 8 year-olds.  In the first part of the season, there will be no stealing allowed and coaches will assist with pitching as needed (i.e. finish pitching to a batter after ball four).   AAA teams will practice twice a week, and play one Tuesday game and one Saturday game.


Important Player Pitch Dates:

Show Your Stuff: Sunday, January 25, 2015

Makeup SYS: Saturday, January 31, 2015

Opening Day:  Saturday, April 18, 2015.


Show Your Stuff

SYS is a mandatory event in which each player registered for Player Pitch baseball will be evaluated.  The evaluation will be used to place each player at the appropriate level and to distribute talent among all teams within a division.  SYS is Sunday, January 26th.  Each player signs up for a specific time.  You can do that the same way you register for any other program.



AA Baseball 8-9 Yrs. Old

*For the first time, registration will be separate for each league.

 “AA” Baseball is advanced machine-pitch baseball for 8 year olds, 7 year olds in 2nd grade** and 9 year olds seeking more development, or a lesser commitment, before playing Player Pitch.  Limited pitching by players will be introduced in the second half of the season.  AA teams will have one weeknight practice per week, one Monday game, one Saturday game, and an end-of-season League Tournament.  Teams may also have some team batting cage time during the season.


A Baseball 7 Yrs. Old 
“A” Baseball is intermediate machine-pitch baseball intended for 7 year olds who have already played a year of Sluggers, 6 year olds in 1st grade** and 8 year olds seeking more development before AA. “A” teams will have one weeknight practice per week, and one Monday game and one Saturday game.


**Players hoping to “play up” an age (7’s in AA, 6’s in A) must have completed the level below and must be ready for the competition and structure of the higher league.  Almost all kids are best suited to play their age appropriate division.  Players who play up must all understand that they may not always be able to do so.  Most commonly, a player will repeat AA because they first played it as a 7 year old and did not qualify for AAA as an 8 year old.




My 8 year-old is a super stud.  Can he play up at the AAA level?

-All interested 8 year-olds must contact the MIBGC at least two weeks prior to SYS.  The MIBGC and MILL VP’s will review each player and decide if the player can participate in SYS.  However, an invitation to SYS is not a guaranteed spot on AAA.  If the player receives high enough scores AND there is room in AAA, the player may be placed in AAA.  If an 8 year-old is invited to SYS, he/she must attend Show Your Stuff to be placed on a AAA team.


My 9 year-old is a super stud.  Can he play in Majors?

-No.  MILL prohibits any player from playing up more than three years.  E.g, 9’s can’t play in Majors.  8’s can’t play in Coast, 7’s can’t play in AAA.


My son was in Coast last season as a 10 year-old.  How come he didn’t move up to Majors this year as an 11 year-old?

-For Majors, the coaches do a live draft of their team.  They select 12 players from all eligible players.  There are some players that are guaranteed places in Majors.  They are (1) League Age 12 year-olds. (2) League Age 11 year-olds in Sixth Grade (who played Coast last season) and (3) Players who played Majors the previous year.  The rest of the remaining players are drafted by the coaches from the pool of eligible players.


How do I figure out my son’s League Age?

-Baseball League Age is determined by your son’s age as of April 30th 2015.  For example, if your son turns 10 on April 30, he is League Age 10.  If your son turns 10 on May 1, he is League Age 9.  There are no exceptions to this rule.  Softball has a different League Age cutoff.  Softball’s cutoff is December 31, 2014.


My league age 9 year-old did not get selected to AAA.  How come?

-At Show Your Stuff, we evaluate over 200 players in order to place them in the division that is most appropriate for them.   We want your child to succeed.  If your child was not placed in AAA we believe that AA was the most appropriate division for them.


My league age 8 year-old did not get selected to AAA even though he already played a year of AA.  How come?


-The most age appropriate division for league age 8 year olds is AA.  Some highly skilled 8 year olds will make AAA, but most will not.  If your child gets placed in AA, we believe AA is the most appropriate division for their abilities.

AAA or Coast




















*League age 10 year olds get split fairly evenly between Coast and AAA.


This chart is a general guideline of progression through Little League baseball.  Some players will experience a different path.  Players are encouraged to stick with their appropriate age unless a different level is recommended to them (typically in player pitch baseball, ages 9-12).
