Dodgers ace Clayton Kershaw, sidelined since late June with a herniated disk in his back, was moved to the 60-day disabled list on Wednesday. Los Angeles manager Dave Roberts said the three-time Cy Young winner hasn't participated in any baseball activity since he suffered a setback in a simulated game July 16. ''He has not thrown, he has not played catch, he has not picked up a baseball,'' Roberts said before the Dodgers faced the Colorado Rockies.
