The Dodgers' pitching staff took another hit Wednesday when Randy Wolf went on the 15-day disabled list because of soreness in his left shoulder. Wolf joins Hong-Chih Kuo, who was demoted to the minors last weekend and went on the DL on Wednesday. Jason Schmidt is already out for the season after elbow surgery, and Yhency Brazoban is sidelined because of a strained right shoulder. Wolf will have an MRI on Thursday and will miss his next scheduled start. He departed after three innings against Atlanta on Tuesday because of tenderness in his shoulder.
