Dallas Mavericks owner Mark Cuban is not involved with any of the groups that have filed paperwork with Major League Baseball in order to view the Mets' books, Cuban told Newsday Wednesday.

Cuban has been interested in owning a baseball team for some time, but failed bids in recent years to buy the Chicago Cubs and Texas Rangers left him with a bitter taste in his mouth. So when the Wilpons announced in January that they are willing to sell up to 25 percent of the team, Cuban said he would be interested only if approached by the owners.

In the weeks since Cuban has said he's been approached by investment groups interested in him joining their efforts to buy a piece of the Mets, but neither the Wilpons nor anyone representing them have approached him.

According to sources, several groups have filed paperwork with Major League Baseball to receive the preliminary approval to view the Mets' books, which is the first step in the process of selling a minority share in the Mets.

Even after they gain that approval and view the books, the interested parties would still have to be vetted by Major League Baseball, including background searches, before a bidding process takes place. Steve Greenberg, the Allen & Co. managing director who is acting as an adviser to the Wilpons, has said the process is likely to take months.
