Ryan Dempster won't pitch in a major league game until after July's All-Star break. "The earliest (he returns ) is sometime after the All-Star break," Cubs manager Dale Sveum said. "We are still are going to wait and be sure everything is built up to whatever he can tolerate, but nothing earlier than that." Dempster, who has been on the disabled list since June 13 with a strained lat muscle, was scheduled to throw on flat ground on Friday.
