The Mira Mesa Youth Baseball League (MMYB) is located in Mira Mesa, a community of San Diego, CA. MMYB is a nonprofit youth benefit corporation and is operated totally by volunteer parents. We provide a safe atmosphere while teaching the game of baseball to boys and girls, ages 4-16, in Mira Mesa and surrounding communities. MMYB is governed by the Official Rules of Major League Baseball and PONY Baseball rules and regulations, which include those exceptions believed essential for our youth baseball program.
