MLB Fan Bases: Ranking MLB Fan Bases by Attendance

8. Houston Astros (Total Attendance 2,980,549; Average Attendance 36,796)

Winning solves everything, as evidence by the fact that the Astros ranked as low as 27th in attendance just five years ago when they were one of the worst teams in baseball. Now that they have won the World Series in 2017 and are one of the best young teams in the MLB, Minute Maid Park is full on most nights.
