There is a league for high school boys to continue playing baseball at the high school level. It is American Legion Baseball. You can get more info at legion.org/baseball . They are starting their season already! They have 19 and under, 17 and under, and 15 and under divisions. If you are interested in playing, contact them directly to inquire.
This is a good heads up for the future; your kiddo can continue to play baseball into high school. Yay!
You can also get more information, closer to home, at americanlegionhawaii.org.
I'm a homeschooling mom of two, enjoying our time in Hawaii and hoping to share some of that experience with you, including ideas, reviews, resources, and information.
