A typical Boston Red Sox game lasts around 2 hours and 40 minutes , with recent seasons showing an average game time between 2:38 and 2:48 due to the introduction of a pitch clock and other pace-of-play rules. Historically, games used to be longer—over 3 hours on average—but recent changes have made games shorter and more fast-paced. Some extraordinary games can last much longer, such as a famous 19-inning game that lasted nearly 7 hours.
