From The Sacramento Bee: A California lawmaker is proposing legislation that would impose a three-year moratorium on the use of metal or composite bats in high school baseball games. Assemblyman Jared Huffman is pushing for a crackdown after Gunnar Sandberg, 16, was critically injured while pitching for Marin Catholic High School when he was struck in the head March 11 by a line drive from a player using a metal bat. Sandberg remains hospitalized in critical condition. Huffman says his three-year moratorium would buy time to explore options that could range from stiffer bat-performance standards to protective headgear for pitchers or a ban on non-wood bats.
