Clayton Richard shipped to DL
The left-handed staple in the Padres' rotation was removed from Friday's start after just two pitches because of pain in the acromioclavicular joint of his left shoulder, near the collarbone.
Richard received an injection on Saturday morning to calm the inflammation that caused him pain, starting after a June 16 start when he allowed one run in eight innings against Arizona.
Richard has had a difficult season, with a 2-5 record and a 7.01 ERA in 12 appearances.
Anthony Bass was promoted from Triple-A Tucson in a corresponding move, and will be available in long relief.
