9:45am: Joel Sherman of the New York Post says (via Twitter) that Bay, Johnny Damon and Matt Holliday remain too expensive for the Yankees.
8:49am: There were indications that Jason Bay and his representatives were active yesterday, according to Michael Silverman of the Boston Herald. The Mets, who are bidding against themselves at the moment, are hesitant to expand their four year offer unless they know which other teams are interested.
The Red Sox never budged from a four-year offer because of concerns about Bay's shoulder and knee, Silverman says. They're not frontrunners to re-sign the left fielder now, but it's too early to rule the Red Sox and Yankees out completely.
Yesterday, we heard that the Mets' offer to Bengie Molina may hinge on their negotiations with Bay, so Bay's decision will influence more than just the outfield market.
