The Mets reached a preliminary agreement Wednesday to acquire Delgado and $7 million from the Florida Marlins for first baseman Mike Jacobs and pitcher Yusmeiro Petit, a baseball official familiar with the talks said, speaking on condition of anonymity because the deal was not final. It is the second tentative deal struck this week by the payroll-slashing Marlins, who also have a pending agreement to send 2003 World Series MVP Josh Beckett to the Boston Red Sox for three prospects. Frustrated they have been unable to put together financing for a new ballpark, the Marlins said Tuesday they have received permission from the commissioner's office to explore moving the franchise for the 2008 season. New York would receive $7 million from the Marlins as part of the trade to offset the $48 million Delgado is owed over the next three seasons. The first baseman turned down the Mets' offer last January to accept a $52 million, four-year contract from the Marlins, who did not offer the no-trade clause contained in the Mets' deal. The sides have not yet agreed on how to spread the money, the official said, with the Mets proposing Florida pays $1 million next year, $2 million in 2007 and $4 million in 2008. The Marlins proposed paying $2.5 million in 2007 and $4.5 million in 2008. The commissioner's office, which must approve the trade because more than $1 million is changing hands, will make the final decision, the official said. Players also must take physicals.
