Approximately 18 minutes of actual action takes place in a regulation baseball game that lasts around three hours, according to a 2013 analysis of three different Major League Baseball (MLB) games performed by the Wall Street Journal. The action may include in-play balls, pitches, and stolen base attempts. However, the vast majority of standard baseball games consist of the players waiting for the action to begin or other breaks, such as pitcher changes, injury breaks, or manager arguments. Over one hour and 14 minutes, or around half of the average MLB game, is spent with breaks between pitches, while between innings breaks comprise around 42 minutes.
