The Los Angeles Dodgers' pitching injury woes aren't likely to go away any time soon. Manager Dave Roberts said surgery ''is more of a possibility'' for Clayton Kershaw after a setback with the herniated disk in his back, and left-hander Alex Wood will miss eight weeks after undergoing arthroscopic surgery on his elbow. Roberts said no doctors told him that surgery was more likely for the three-time National League Cy Young Award winner but inferred that based on the type of injury.
