Fenway Park, the home of the Boston Red Sox baseball team, can accommodate 37,071 spectators when configured for daytime seating. Fenway Park holds the record for most consecutive sellout games, with a streak of 794 sellouts that ended in 2013. This figure is a dramatic turnaround from the attendance in 1965, which was at times as low as just 500 people.
