Welcome to Orinda Baseball Association!

Weather and Field Updates

All Field closures  are made by OUSD and The City of Orinda. OBA will work with the city and school district to announce field closures on days impacted by rain or weather by 2pm each day with updates directly to this site.

*Please note: Some fields drain and absorb rainwater differently, so some fields may be open while others are closed.*

OPENING DAY, March 2nd!

We're just under a month away from OBA Opening Day on Saturday, March 2nd, from 8:30AM to 11:30AM at Wagner Ranch Elementary School – rain or shine! This Opening Day event kicks off our 2024 season with baseball games beginning after the opening ceremony and continuing through the weekend. 


We have some great things in store for the whole family. We’ll have lots of food options – breakfast burritos, donuts, coffee, plus other snacks & beverages. There will be carnival games, a photo booth, speed pitch, raffle prizes and an awards ceremony to recognize our past and present athletes.


And we're bringing back the virtual Home Run Derby fundraiser! In partnership with Bay Area Ballplayers, we’re bringing the batting cages to you!


Register your player today on our PledgeIt campaign page then reach out to friends and family between now and Opening Day (instructions & tips below) to gather pledges based on your player’s home run goals (e.g. $10 per home run hit). On Opening Day, each registered player will step into the mobile batting cage and will get 10 pitches via a soft toss machine (or batting tee).


HitTrax technology measures the exit velocity and launch angle of each ball hit, while simultaneously showing the virtual results in real-time.


The team that raises the most funds for OBA wins a prize (to be announced soon) and the top individual players in each division will also win prizes.


So rally your teammates, friends and family and get ready to compete in the OBA Opening Day Home Run Derby on Saturday, March 2nd from 8:30AM - 11:30AM.


Players should arrive dressed in uniform for team photos (photo schedule coming soon) and the much-anticipated parade of teams! Plus we’ll have OBA t-shirts, hoodies and hats for sale. 


Here are the details:
