Breaking News



Fall Ball at the JBO level is structured to allow players new to JBO to get a taste of advanced, tourney style baseball.  Importantly, players rising out of Little League will have a chance to play on the full 90’ diamond (the same size as the high school, college and pros), most for the first time.   Getting a taste for the field size, throws required, pitching, and hitting is very important so that the 2023 Spring Evaluations aren’t the first time they’ve competed on the full sized field. 

For those returning to JBO and/or experience in tournament ball, Fall Ball is a great opportunity to stay sharp, refine their skills and gain valuable experience heading into next Spring. Fall Ball Notes:

  • Cost: $125- Minors & Juniors; $135- Senior
  • Dates of Play: September 11-October 16th
  • Days of Play: ONLY Sundays- this allows players competing in other Fall Sports (football, soccer, lax, etc) the ability to better work Fall Ball into their athletic schedules.
  • Age Divisions: Entering 3rd/4th (Minors); Entering 5th/6th (Juniors); Entering 7th/8th (Senior)
  • What Age Division do I register my player?   Register your player based on what grade they will be in for the 2022-3 school year, which is their rising grade.

When does practice start?   This will vary depending on the Coach, but expect practice to start the week before or after Labor Day.

How many practices will we have per week?  Generally 1 per week in the early weeks is the standard for Fall Ball, with some tapering off as the season progresses.  Because of the high cost of THPRD fields, coupled with keeping costs down, multiple practices/week are not practical

What is included?   Team registration, Hat, and T-shirt Jersey

Last year, we had tremendous demand and expect similarly.

Registering early and ensuring a team placement is advised.

About Mountainside JBO

Mountainside Junior Baseball Organization (JBO) is a 501(c)(3) non-profit organization that was established in 2017 to compete as an affiliate in Oregon's Westside JBO district, while offering a youth baseball playing alternative in the Mountainside High School district.

The Mountainside JBO program is directly aligned with Mountainside High School and works closely with Ryan Fobert, the Mountainside High School Head Varsity baseball coach, and his coaching staff.   This strategic alignment aims in helping to provide the area's youth with the development, skills and competition needed to not only flourish as youth players, but also provide a segue to high school baseball.  

The goal of Mountainside JBO is to build a league of players who reside in the Mountainside High School boundaries and allow them to compete against other players of equal age and skill, while ultimately achieving their full baseball potential. And because of its connection to the the high school program, Mountainside JBO is in a unique position to prepare your child to play High School Baseball at Mountainside.
