Zachary Austin, 6, appears to focus his entire concentration and energy into a swing Monday during the baseball and T-ball clinic at Bicentennial Park in Crystal River. The clinic, conducted by Rich Luppino's United Sports Academy, was for boys and girls ages 4-8. They learned hitting, base running and fielding. "They were great," Luppino said. "They were all just little guys, but they really wanted to learn."
