A few months back I wrote about a NY Times study of how much playing time actual takes place during an NFL game. The total was a bit over 10 minutes. Today, the same guys did the same thing for baseball, and determined that the ball is in play 14minutes. Either way, you get a lot of time to read during the course of a game.
The story, which I have not linked to because the Journal has a pay wall, also discusses the percentage of time that the game is on TV that is taken up by play, as well as by other shots. It seems the biggest chunk is "players standing around".
The data came from only watching 2 games on TV, so is not accurate, but feels about right. Of course, if they were watching the Yankees, they would have to add time for "players refusing to get into the batters box". You East coast fans will want to move out here to Colorado as those Yankees playoff games stretch over 4 hours while Derek Jeter adjusts his gloves and cup.
I will repeat a stat that I have written about before, and you can bemoan as you watch the 4 hour baseball playoff games. The greatest game in baseball history, game 7 of the 1960 World Series that ended with Bill Mazaroski's home run to give the Pirates a 10-9 victory over the forces of evil, lasted 2 hours, 28 minutes.
