[Sylmar Independent Baseball League - Sylmar Independent Baseball League Sylmar Independent Baseball League was founded in 1957 and was located at two sites before moving to its current location to make way for Mission College at Hubbard and Eldridge. SIBL owns the property and is well on its way back to health. SIBL has restored its non-profit status and has paid in full all property taxes. SIBL's Directors have the knowledge and the perseverance to turn SIBL back into the source of pride in our community it once was. We encourage all interested to come and help us, volunteer your time and contribute service, material and money to assure that this facility will be the best it can be forever!.]
