Overzealous sports fans could face up to $25,000 in fines under a law passed yesterday by the New York City Council to crack down on rowdy spectators.

The city already is known for enforcing the nation's toughest penalties for fans who run onto a playing field or floor.

City Council member Peter Vallone Jr., who authored the city's strict 2003 law against spectators running amok, came up with the new measure during Game 6 of the AL Championship Series between the Yankees and Boston Red Sox two years ago.

After umpires reversed a call in the eighth inning, fans threw plastic bottles and other debris onto the field. Announcements were made asking the fans to stop, and when that didn't work, helmeted police marched out and knelt shoulder-to-shoulder along the stands for part of the game.

The new measure, which is an amendment to his earlier law, passed without opposition and takes effect when Mayor Michael Bloomberg signs it. Bloomberg spokesman Ed Skyler said the mayor supports the change.

* BOXING: Fresh from dealing with baseball and steroids, Congress chose not to step into the ring as boxing's referee, voting down a bill to create a federal agency to protect fighters' health and wallets.

The House voted 233-190 against forming a U.S. Boxing Commission within the Commerce Department. Most Republicans opposed the measure, while most Democrats voted for it. Critics attacked the bill as a misguided effort to expand the federal government to manage a part of the entertainment industry.
