3. Re: How long is a Baseball game. Jun 22, 2011, 3:59 PM. There is a website called Beyond the Box score that keeps track of game times by each team. The Yankees werre the longest in the Majors per 9 innings. Last year my team the St. Louis Cardinals played a 20 inning game against the NY Mutts. So really depends on how long the game is. Like what Al-NYC said, a game usually takes 3-4 hours long. It depends it there is a lot of scoring or not.
