The present invention relates to a baseball swing trainer. In a first embodiment, a ball is pivotally attached to a vertical arm which is slidably attached to an oblique arm, the oblique arm is attached to a horizontal arm which is attached to a support structure; the vertical arm is contained within a first and second guide arm; a stopping member is attached to a first end of the oblique arm and a stopping bar is attached to a second end of the oblique arm such that when the ball is struck, the ball pivots on the vertical arm as the vertical arm slides up the oblique arm, striking the stopping bar and thereafter sliding back down the oblique arm to return to its starting position cradled within the stopping member. The travel path of the ball provides instantaneous feedback as to the quality of the swing.
