Rafael ...I wanted you to know what a diference Big League Baseball Instruction has made in my son's hitting ability. He is more confident, more patient in the counts, more technically efficient, able to go to the oposite field at will, and excited to hit. His work with yourself, Danny, and Desi has made the game more fun for him. Thank you for your expertise.
