Abstract: An L-screen for protecting a pitcher during batting practice is disclosed. The L-screen may include a plurality of panel frames configured to be interrelated with one another so as to form an L-shape. A solid protection panel may be mounted within each of the panel frames. The protection panel may be transparent so as to provide an unobstructed view through the protection panel and may have adequate strength to withstand the impact of a baseball hit by a batter. Additionally, the L-screen may include support structure mounted to and configured to support the L-screen.
