Authorities say there will be strong consequences for any acts of vandalism, and they've already put prevention measures in place.
On South Broad on Wednesday, city workers greased down polls and other stationary objects to prevent any dangerous climbing. This was carried out in other traditional hot spots from South Philadelphia on up into the Northeast.
Strapped to those polls were wire-meshed trash cans. They are replacements for the state of the art receptacles recently deployed. Parking is already restricted along South Broad, which was the major battleground with drunken rowdies last year.
100 security cameras citywide will keep a watchful eye on celebrants.
Despite these efforts, police say they still hope the Phillies will repeat, but they are promising the hoodlum element will not.
"Any acts of vandalism will not be tolerated, and will be dealt with swiftly," said Dep. Commissioner Richard Ross.
Last year, thousands of orderly revelers filled Center City, but after midnight several bands of violent drunks, most of them college students, took over the streets breaking windows, looting a luggage store and toppling traffic polls and planters.
In all, 70 people were arrested, and police say there will be an immediate crackdown if people try such violence again.
"This year I assure you the Philadelphia Police Department and the State Police will be out there in force, ensuring that people celebrate responsibly and if they don't there will be repercussions," Ross said.
"I can assume that Philadelphians, and Phillies fans, will conduct themselves in the most rational, reasonable and responsible manner. Otherwise, of course, there are consquences," said Mayor Michael Nutter.
