Chris Withrow adds back surgery to offseason

LOS ANGELES -- Dodgers pitcher Chris Withrow is no stranger to rehabilitation, and will add to his offseason recuperation plans after undergoing surgery last week to repair a herniated disc on his lower back, per Ken Gurnick of MLB.com.

The recovery period for Withrow after the surgery is three months, per Gurnick, but isn't expected to affect his timetable to return to the mound. The right-hander had Tommy John surgery on June 3 in Florida to repair a torn ulnar collateral ligament in his right elbow, and isn't expected to return until roughly the All-Star break in 2015.

Withrow, who turns 26 on April 1, has a 2.73 major league ERA in 46 career relief appearances over 2013-2014, with 71 strikeouts and 31 walks in 56 innings. The right-hander worked his way to a key setup role in 2014, putting up a 2.95 ERA in 20 relief appearances with 28 strikeouts and 18 walks in 21⅓ innings before suffering the elbow injury in May.

Drafted in the first round in 2007, Withrow is the seventh-longest tenured Dodger in the organization, trailing only Pedro Baez (signed in January 2007), Carlos Frias (signed in January 2007), Clayton Kershaw (drafted in 2006), Andre Ethier (acquired by trade in 2006), Kenley Jansen (signed in 2004) and A.J. Ellis (drafted in 2003).
