Add Dustin Pedroia to the growing list of Red Sox who have gone under the knife already this offseason.

In a brief statement today, the Red Sox said Pedroia underwent a successful cartilage restoration procedure on his left knee. The procedure was performed by Dr. Riley Williams III at the Hospital for Special Surgery in New York.

The Sox said Pedroia’s recovery timeline is seven months, meaning he won’t make his return until late May 2018, at the earliest. It will be Pedroia’s first time off the Opening Day Roster in the last 11 of his 12 big league seasons (2007-17).

Pedroia’s streak of 11 Opening Day starts was eighth longest in Red Sox club history since 1913. Hall of Famer Carl Yastrzemski had the most such starts (22, 1961-1980, 1982-83), followed by Dwight Evans (17), and Hall of Famer Jim Rice (14).

Pedroia’s sidelining means an added dimension of offseason maneuvering for Red Sox baseball president Dave Dombrowski.

More Surgeries, More Recoveries

Since this season ended, three other Red Sox have undergone surgical procedures: Eduardo Rodríguez (reconstruction of the patellofemoral ligament in his right knee) and Robby Scott (left elbow arthroscopy and debridement), and Hanley Ramírez (left shoulder arthroscopy and debridement).

Ramírez and Scott should be ready for Spring Training. Rodríguez’ recovery will keep him idle until at least April.

All four procedures have come subsequent to Dombrowski’s October 11 press conference announcing the firing of former manager John Farrell. At that time, Dombrowksi told the press he was unaware of any players who needed surgery.
