What is the difference between Travel Ball and Club Ball?

Two distinct softball programs tailored to different player commitments and skill levels: the Club Ball program and the Travel Ball program.

Club Ball Program: This program is ideal for players who are developing their skills and may not be ready for travel ball commitments or those whose families are unavailable during the summer. Teams are geographically formed and available for 8U, 10U, and 12U players. Teams practice once a week and play back-to-back games on Saturday mornings.

Travel Ball Program (Black & Gold): Geared towards players deeply passionate about softball, our Black and Gold programs involve more competitive and frequent gameplay. Players must demonstrate their skills at tryouts to be selected to our 8U, 10U, 12U, and 14U players. Teams practice 2 to 3 times per week and participate in 5 to 6 local tournaments in the North Bay area.
