The Mets are among the at least half-dozen teams that have inquired seriously about Oakland closer Andrew Bailey, a person familiar with those talks told The Post.

However, the A's are selling high on the righty and currently do not believe the Mets have the necessary pieces to obtain Bailey, a two-time All-Star and the 2009 AL Rookie of the Year. The Reds, Rangers and Blue Jays are among the teams that are pursuing Bailey, a New Jersey native who went to college at Wagner.
