Turner, 29, batted .280 with two home runs and 16 RBIs in 86 games with the Mets last season. He appeared in games at all four infield positions and one in left field.
The former Mayfair High and Cal State Fullerton standout has a .260 batting average with eight homers and 89 RBIs in 318 games over five seasons.
Turner figures to compete with Dee Gordon and non-roster invitees Chone Figgins, Brendan Harris and Miguel Rojas for backup roles. If Alex Guerrero fails to impress in his first major-league spring training, all four players could vie for the Opening Day second baseman job.
