A baseball/softball practice and teaching aid apparatus which functions as a batting tee and swing corrector or as a pitching target is disclosed. A slightly modified home plate is provided with a centrally mounted and vertically adjustable post which can be rotated about its vertical axis. A vertically adjustable ball support post is attached to the centrally mounted post by an adjustable horizontal cross bar member and can be extended and retracted in a lateral direction from the centrally mounted post and can be moved in an arcuate path around the home plate and the post vertical axis. The forward corners of the plate have been removed in order that the ball support arm can be rotated into a position which allows for practice balls to be placed directly over the corners of the plate. An optional line-of-sight band is positioned between the centrally mounted post and the ball support arm to give batters swing sight guidance.
