how many balls does major league baseball use in a season?
There are 30 teams playing each other in 162 games each. So there are (15 x 162 = 2,430) games per season, (you have to divide the total number of teams by two, since each game has two teams in it). That equals: (2,430 x 65) baseballs used per season, which totals 157,950 baseballs used during games per regular season.
