Frank Viola and the New York Mets failed to agree on a contract extension Saturday and the left-hander says he's headed for free agency after the season.

Viola, 20-12 in 1990, is looking for a deal similar to the one the Mets gave Dwight Gooden last Monday. Gooden signed a three-year deal for $15.45 million and he can make as much as $16.2 million with incentives.The Mets have offered Viola $13 million for three years, up from their last offer of $12.5 million.

"Frank enjoys playing for the Mets but not enough to forfeit millions of dollars," said Viola's agent, Craig Fenech. "Why should he sign for a million dollars less than he can get as a free agent?"
