Breaking News- Important Updates

Evaluations- JUNIORS/MINORS Divisions- March 6

We will be holding joint JUNIOR & MINORS Division Evaluations on March 6th, from 2:30-6:30 pm.  After registration is closed on March 4th for these levels, a time slot will be sent out to families on March 5th, providing more detailed instructions, as well as an assigned time slot.

The evals will be held  at the THPRD HMT complex, at the turf soccer field, located at 15707 SW Walker Rd; Beaverton, OR 97006

These evaluations will determine what level our Juniors (5th/6th) and Minors (3rd/4th) players will play at for the 2021 Spring season- Fed (highest), American (mid) or National.  

Participation is mandatory to be considered for the Federal and American teams.  No exceptions except extraordinary ones.  

RAIN or SHINE.  So, keep an eye on the weather forecasts and plan to dress appropriately.  

** Note:  A league can have all upper level teams if that is where the talent level dictates.   There doesn't have to be a team at all levels.  Although that is rare.   The goal is to place kids on teams where they can be simultaneously challenged and successful.  

Extended Evaluation Information

More information can be found by clicking on the "Extended Evaluation Information" blue bar above, which will take you to our Tryouts section on our The Dugout/Players Tab at the top of the page.


Mountainside JBO has plans for a Spring season, with JBO sanctioned games starting the week of May 17th and concluding in mid to late July, prior to the Westside District tournament.   Westside JBO will have District Tournament but to extend the season, Westside JBO programs have voted to forego the State tournament this year.

Player evaluations/tryouts are slated to start on February 26 for our Senior Division, with Junior and Minors Divisions to follow on March 6th.  Leaguewide team practices are slated to start by mid March , shortly after all all evaluations have been completed and teams have been formed and as THPRD allows field usage.

Some teams, depending on coach preference, may have open tournaments scheduled as early as March/April.  

We're also looking to offer on-field advanced player development clinics starting in March on turf baseball field(s) and/or in our contracted indoor batting cages.   Details of the clinic and cage schedules to be announced in the next couple of weeks.

Like all area youth athletic & baseball leagues, Mountainside JBO's season is contingent on having BSD school field availability, but signs are looking extremely positive for the 2021 Spring Season to commence.  There is continued optimism  from Westside JBO, OSAA, THPRD and Mountainside JBO that the school fields will be available for use by the anticipated start of our preseason practice and leading up to the game season, but there is no guarantee at this juncture.   But know we are doing everything in our power to let the kids play baseball this season.  

We will continue to monitor the Governor’s orders and the local and/or state restrictions and communicate additional information to you as soon as it becomes available.

Happy Baseball!

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.
