Justin Turner is headed into his first arbitration year which is sometimes when decent players are non-tendered. But a Mets source said that the team projects Turner to make less than $1 million next year which it does not see as an overpay for Turner’s production. While there is no guarantee that Turner will return in the backup infield role that he has held since 2011 -- the Mets’ roster has too many questions for any guarantees other than the third baseman -- team officials have been impressed by his maturation as a hitter ability to take a professional at-bat off the bench and presence in the dugout and clubhouse. Turner the Mets have noticed always seems engaged in games sometimes even talking strategy with Terry Collins when he isn’t playing. Behavior like that doesn’t win anyone a job but when the team is making roster decisions it doesn’t hurt either.
