    Expression for X position and shadow effect question

      I have an animated ping pong ball on real footage of a table tennis match and I need to set up an expression of the same ball so that this ball copy follows the X position but not the Y position of the ball for the shadow.

      This is going to serve as the shadow of the ball (probably use the 'drop shadow, shadow only' effect): so I want the shadow to follow the balls path and then use opacity to show the ball's shadow when it hits the table, obviously gaining in opacity when it nears the table.

      Can anyone tell me what the expression would be just for the x position and can anyone suggest a good way to make the shadow if my way is stupid? I was thinking maybe the drop shadow effect or perhaps set up a plane in 3D for the shadow to fall on?
