"He's had it for a few days," Collins said. "He's just gotten worse the last couple days, so we had him looked at."
With the Mets scheduled to play five games in four days in Atlanta, and in need of roster spots to make room for pitchers Zack Wheeler and Scott Atchison, they may simply disable Turner and proceed with an extra arm for the immediate future. That would eliminate the need to cut anyone before Tuesday, thanks to an MLB rule that allows teams to carry 26 players for previously-scheduled doubleheaders.
But the Mets will still have to make another roster move after the doubleheader.
Turner is in the midst of an 8-for-50 slump, lowering his average from .378 at its peak to .266. He has made spot starts at all four infield positions, appearing most frequently at first base.
