Apparently, the signing of Matt Diaz has not affected the Yankees’ interest in Scott Hairston. Further, there are reportedly other teams in addition to the Yanks interested in the slugging Hairston. Though Hairston has stated his desire to return to the Mets, there remains a very real possibility his 2013 home team does not reside in Flushing. If Hairston signs elsewhere, who is going to be the Mets’ fourth outfielder?
