Joel Sherman of the New York Post reports that the Mets have re-signed Scott Hairston. Exact terms aren't yet available. Hairston, 31, batted .235/.303/.470 with seven homers, 24 RBI and a .773 OPS over 145 plate appearances in 2011 before suffering a season-ending oblique injury in late-August. He'll function as a reserve outfielder and right-handed bat off the bench again in 2012.
