The New York Mets have re-signed backup outfielder Scott Hairston to a one-year, $1.1 million major-league contract, as first reported by Joel Sherman of the New York Post and Andy Martino of the New York Daily News.

Hairston, 31, hit .235/.303/.470 in 145 plate appearances last season for the Mets. Like in 2011, Hairston will serve as a reserve outfielder for the club at all three outfield positions.

As Adam Rubin of ESPN notes, the Mets' 40-man roster is currently full. To add Hairston, the team will need to make a roster move, and that is likely the only thing holding up an official announcement.

Now with Hairston signed, the Mets aren't likely to re-sign Willie Harris to a deal, according to the New York Daily News' Andy Martino.
