Richard was originally placed on the disabled list earlier this month with what was termed as a strained left shoulder. Padres manager Bud Black said the exploratory surgery was deemed necessary after his shoulder failed to respond to treatment.
“He wasn’t progressing to the point where rehab or a strengthening program was going to help,” Black said.
Richard opted for the surgery after getting a second opinion from Dr. Lewis Yocum on Thursday. Padres team physicians Dr. Heinz Hoenecke and Dr. Jan Fronek smoothed out the glenoid labrum, biceps tendon and rotator cuff.
Richard went 5-9 with a 3.88 ERA over 18 starts this season, though his velocity and strikeout rates were both down from where they were last season.
