- a pitching rubber centrally mounted on the upper surface of said shell member,
- a depression area formed in said shell member and extending at least from said pitching rubber forwardly and outwardly to the forward end of said shell member,
- and a panel, including a resilient and frictional cushion material, mounted in said depression to provide frictional footing to a pitcher pitching from said pitching rubber so that the force transmitted by a pitcher's foot to said shell is partially absorbed,
