"We haven't ruled anything out," the official said. "We need a closer. It is a long way down the road. We haven't had those meetings yet. But, for us, I wouldn't rule anything out."
Rodriguez, 29, recently said he would consider a return to Queens.
"Of course," Rodriguez told Newsday. "I don't have no hard feelings for nobody. They did what they had to do. They needed to unload a lot of money and I was making too much money. But you never know what's going to happen one year from now, two years from now."
A second Mets official said: "A lot would have to line up for (a return to) come true. He didn't leave on the worst of terms. We made the trade more because of money. It is not an absolute no. It is possible, not probable."
The Mets traded Rodriguez for Adrian Rosario and Danny Herrera plus cash to the Milwaukee Brewers on the day of the All-Star Game to get out from under his large contract. While Rodriguez pitched pretty well as a Met, his time in Flushing was marred by an off-the-field incident in which he was arrested for assaulting the father of his girlfriend at Citi Field during the 2010 season.
With Rodriguez looking for a huge payday and the Mets trying to trim payroll, it seems very unlikely a reunion will take place, but both sides, at least for now, are saying there is a chance.
