Baseball is a game.
Games are meant to be fun. It can be very easy to get caught up in the competition, just be very careful not to say anything damaging that the kids may hear. It is a child's nature to enjoy games and activities. It is from the influential people in their lives that they learn whether to enjoy the game or not. There is plenty of time for competition when your child gets older.
