In modern day baseball, teams generally have five starting pitchers, and they take it in turn to start a game every fifth day (hence the phrase rotation). Sometimes, if the schedule pans out, a team can get away with a four man rotation, and in the distant past some teams managed a three man rotation.
That game used 104 baseballs, which is about 15 fewer than average, according to the Pirates' equipment manager. So not only is it ridiculous to say that an MLB team is only required to have 90 baseballs on hand, the average number of baseballs used in a game is about 120. Posted by Greg McConnell at 4:30 AM.
