In a typical 9-inning MLB game, between 60 and 70 baseballs are utilized. A few more than this number are used in an average game because some balls get lost under the stands or become damaged during use. The number of balls used in a game is one of many factors that determine how much it costs to attend a ball game. The more balls that are thrown into the stands, the more tickets that will be sold. Also, if the ball park has a special area where only worn out balls are placed, this would increase the number of balls used in the game. Every time a batter takes strike three he signals the umpire who is standing behind the plate. This signal means that the batter believes there are no more balls left in the ball game. When this happens, the ump throws down his mask and runs to first base while shouting "Out!" At this point, the game ends and the batter(s) and all players involved in the play are removed from the field. As soon as the out is made, the home team's manager starts counting off players to take up defensive positions around the ball park.
