SEATTLE - AL Cy Young Award winner Roy Halladay missed his scheduled start for Toronto against Seattle on Tuesday night because of a sore right shoulder.

Halladay, 5-4 with a 3.58 ERA in 11 starts this season, will be examined by a doctor in Seattle. Blue Jays manager Carlos Tosca hopes Halladay will be able to pitch by Sunday.

Halladay, 26, was replaced Tuesday by left-hander Jason Kershner, who has made 19 relief appearances for the Blue Jays this season. He had never started a game in the major leagues.

NEW YORK: The Mets might follow the lead of the crosstown Yankees and start their own cable television network.

The Mets paid $54 million last week to buy out the remainder of their contract with Madison Square Garden Network and Fox Sports Net New York, exercising their right to terminate the deal after the 2005 season.

The Mets retained former deputy baseball commissioner Steve Greenberg of Allen & Co. to represent them in TV discussions and issued a statement saying they will "explore all options."

SHORT HOPS: Right-hander Jason Anderson rejoined the New York Yankees' organization Tuesday when he was claimed off waivers from Cleveland.

• St. Louis third baseman Scott Rolen left Tuesday's game against Pittsburgh shortly after he was hit in the helmet with a pitch. A team official said Rolen was taken out for precautionary reasons and will be reevaluated today.
