Michael Cuddyer had surgery Thursday for a core muscle injury, the Mets announced Friday. The procedure was performed at Vincera Institute in Philadelphia.
It's unclear how long Cuddyer has been dealing with the injury. He missed time earlier in the season with a knee problem.
Cuddyer endured a forgettable first season with the Mets after signing a two-year, $21-million deal a year ago that also cost the team a first-round draft pick.
Cuddyer, 36, hit just .259 with 10 home runs and 41 RBIs. He began the season as the starting leftfielder but took a backseat as part of a platoon with prospect Michael Conforto.
Next season, Conforto is expected to take on full-time duties in leftfield, leaving Cuddyer in a bench role. He could wind up a platoon partner for Lucas Duda at first base. He could also spell either Conforto or Curtis Granderson against some lefthanded pitchers.
The Mets also announced that catcher Anthony Recker, infielder Wilfredo Tovar and outfielder Eric Young Jr. have elected free agency.
