Diamondbacks ace Brandon Webb could start the season on the disabled list. Arizona general manager Josh Byrnes acknowledged Friday that Webb could be placed on the DL if he doesn't start showing progress soon in his comeback from shoulder surgery. "It's a long season," Byrnes said. "If we get 30 starts from him, great. If we get 20, that's great. I think we just need to get it right. "His shoulder is strong. He's done a lot of work. Now I think it's more a function of the inactivity -- 10 months between being on the mound. In many respects, he's about where we want him to be. But he needs to have four or five spring training starts to be ready for the first regular-season start. If that's going to happen, we need to know fairly soon."
