What am I?
1. I am made of wood and I am a little shorter than a cricket wicket.
2. I was used in a contest of sport.
3. I stuck in the ground.
4. My sport is quite young, as sports go and I am played on a green.
5. With me you will find mallets, balls and hoops. Players try to hit me at the end of the game.
