Boston is closing down some streets and restricting parking for the final three games of the World Series.
Police on Sunday announced that the closures and restrictions are being put in place "to ensure the safety and security of fans following the Fall Classic."
Impromptu celebrations in Boston after previous sports championships have resulted in vandalism and even deaths.
Many streets around Fenway Park will be closed to traffic from 10 p.m. until 3 a.m. on game nights, no matter who wins. Temporary parking restrictions will be put in place in several areas, particularly where many students live.
Police said "fans, whether they support the Red Sox or Dodgers, are expected to behave responsibly and show respect to both people and property."
Game 5 is Sunday night.
