Abstract: A baseball pitching machine is disclosed preferably employing a counterrotating wheel type baseball launch subsystem pitching a series of baseballs and a computer controlled system for selecting the type and percentage of pitches, pitcher and batter characteristics, strike zone areas and other parameters to provide a meaningful batting training session. The pitching machine includes a ball transport subsystem including a carousel for receiving and transporting baseballs in sequence to a position adjacent the counter rotating wheels. While being transported, each baseball stops at seam orienting stations where seam rotators rotate the baseball to provide a commanded seam orientation for the particular pitch selected. The baseball is oriented by the ball orienter for insertion in the launch subsystem. A computer allows the selection by the operator of a variety of pitches, random or selected order.
