If we don't learn that, the game will be more frustrating than fun. And, if we don't come up when it is our time to bat, then Jesus will get another one who is willing. Girls can play just as well as boys in team sports like baseball. That's why he gave the higher gifts to girls, too. If the boys have trouble with that, perhaps they should go back to Marbles or Hopscotch and learn what they missed there.
Cooperation is the task to learn on team games.
If you spend your time fighting or sleeping, you are not busy paying attention. Not being alert means a roaring lion might come get you. And if you are foolish enough to throw a ball at a teammate's head, Jesus doesn't take too kindly to that. You should know who your enemy is, and no one said you were supposed to be like the enemy, too. It is better to go back to snowball fights, if you like to throw so much.
