Come and help us vote in new and existing members. This is a great opportunity to get involved in Milwaukie Youth Baseball. Not sure you're ready to sign up as a board member? We still would love your input and enthusiasm as we create the best organization we can. Help us get the word out and share this email with friend or folks you think might be interested! The MJBA is an all volunteer organization and we need help at all levels on and off the field! There is no way to create change than getting involved! 




Milwaukie Junior Baseball would like to thank all the players, coaches, sponsors and families of baseball. This was one of the best seasons of baseball we have seen in Milwaukie for years! It's a lot of very hard work and lots of long evenings, but boy is it worth it! A special thanks to all our great coaches and assistant coaches who make it all possible and are such a wonderful influence on our players and families! We are already getting ready for next year! See you all at Fall Ball!!

Welcome to Milwaukie Junior Baseball!

2015 Registration is Now Closed. 

Milwaukie Junior Baseball Association (MJBA) provides opportunities for players from 5 to 14 years of age or players in grades Kindergarten through 8th grade. Players are grouped into five distinct age divisions: 

• T-ball is for players aged 5 through 7 or in Kindergarten through 1st grade. To see T-ball rules see Printable Forms section.

• Rookie ball is for players aged 6 through 8 or in 1st or 2nd grade. The players' ability to catch a baseball is usually what distinguishes rookie ball from a t-ball. To see Rookie ball rules see Printable Forms section.

• The Midget Division is for players aged 9 and 10 or in 3rd and 4th grade.

• The Junior Division is for players aged 11 and 12 or in 5th or 6th grade.

• The Senior Division is for players aged 13 and 14 or in 7th or 8th grade. 

The age of the players is generally determined by their age on July 31 of the year of the baseball season, though there are exceptions for older players who wish to participate with their school classmates. 

Within the Midget, Junior and Senior divisions players are also separated into three distinct skill levels. The separation is necessary to meet the Junior Baseball Organization goal of assuring that all players participate against other players of equal age and skill. Therefore, Midget, Junior and Senior division players are required to attend at least one tryout. The National level is for players with beginning or recreation level skills. The American level is for intermediate skills, and the Federal level is for players with the highest skill level.
