How many baseballs are used during the course of an average major league baseball game?

I found this.

I remember watching a Mariners game where the broadcasters were asked this, so they counted every ball that game. I cannot remember the exact number, but it was in the 70–80 range.

The good news is the teams use them in practice, send them to the monir leagues and training leagues until they are well re-used.

This was the subject of a feature news story on the Yahoo new pages just this week. It must be a burning question. If I remember correctly the report said they are changed about every 6 pitches, and the used balls are then re-used in the practice sessions.

i believe that each team has almost a gross (a dozen dozen) available at each game. They are changed out anytime that it is needed or if the pitcher is just tired of the ball he’s using for whatever reason. They for the most part never reuse the balls in that game, but yes they do use them in practices that come after the games.
