MLB games are shorter than an average NFL game - but it's far more reasonable for fans to spend three hours watching a football game once a week than the same amount of time every day to follow their favorite baseball team. Baseball games are getting longer this season, though. According to ESPN, the length of average MLB game in 2016 has stretched three hours and 26 seconds. That doesn't sound like a huge increase, but when you add four minutes to 2,430 games a year in the regular season, it adds up to an additional 6.83 days worth of baseball.
Major League Baseball average game times are down almost 8 1/2 minutes from 2014, thanks to the leagueâs new pace-of-game rules. Thatâs good news not just for fans, but players as well; ESPN reports that MLB officials and the players union are in discussions to drop the fines for slow play the league could impose beginning Friday.
