Since 1972, Mira Mesa Youth Baseball (MMYB) has operated as a non-profit youth benefit corporation and is ran completely by volunteer parents. We provide a safe atmosphere for teaching the game of baseball to boys and girls, ages 3-14, for Mira Mesa, Carmel Valley, Carmel Mountain, Poway, Rancho Penasquitos, Rancho Bernardo, Scripps Ranch and other surrounding communities.
