The Phils and CBS announced this week that they had signed an extension to their five-year contract, keeping WPHT (1210) as the team's flagship station.

The length of the extension was not disclosed, but my sources pin it at only one year: the 2010 season.

John Fullam, who runs Greater Media's Philadelphia stations, said he was hot to "sit at the table" next year to bid not only for the Phils but the other major area teams - all of which have radio deals with CBS. (No other deal is coming up soon.)

Last week, Greater Media added a 97.5 FM simulcast to WPEN (950), its sports-talk station. WPEN, also known as 950ESPN, is gunning for the audience of CBS sports-talker WIP (610).

The Phillies have a long history with WPHT. Their games were heard on the 50,000-watt station from 1982 to 2001. From 2002 to 2004, the Phils jumped to the 5,000-watt WPEN, which was still a music station. Complaints of static were frequent then, but 97.5 throws a decent FM signal across the region.

CBS wrested back the Phillies with a five-year deal starting with the 2005 season.

WPEN carries postseason games through its affiliation with ESPN - including the Phillies games. All Major League Baseball games also are heard on XM.
