In the 35 nine-inning games played through last night, the average length of a MLB game has been 2 hours, 52 minutes , according to Michael Teevan, spokesperson for Major League Baseball.
How long is the average baseball game? Answer   The average 9 inning ball game should last about 3 to 3 and a half hours. If one team is physically dominating the other (i.e.-any team that plays Tampa Bay hahaâ¦!) then the game could last 4 to 5 hours.
