According to David Lennon of Newsday, the Mets will make offers to Francisco Rodriguez and Brian Fuentes this week, and perhaps Derek Lowe and other starters.
Rather than attempt to scare other teams off with massive initial bids, the Mets will make small offers and work their way up. It seems that the sticking point with K-Rod will be guaranteeing a fourth year. That was what they had to do to get Billy Wagner three years ago.
