Abstract: A target training system and method for baseball pitchers employs a target sheet mounted on a supporting structure so that a facing surface of the target sheet is vertical and a bottom of the target sheet is at ground level. Hitter shoulder level, waist level, and knee level lines are provided on the facing surface of the target sheet. First and second vertical boundary lines running from a top to a bottom of the sheet indicate a width of a strike zone. A plurality of boxes of differing colors and having differing sequencing indicia representing relatively high quality pitches are arranged in and around the strike zone. Regions having a white color within and near the strike zone and exclusive of the colored boxes are provided, the regions being exclusionary zones representing relatively poor quality pitches. Some of the boxes are subdivided to permit pitching to progressively smaller targets. Separate target sheets are provided for different skill levels.
