Phillies closer Brad Lidge acknowledged Friday that he won't be ready for Opening Day due to soreness in the back of his shoulder, according to an ESPN.com report. "We're optimistic and hoping that it will be only a couple of weeks, and not much past that," Lidge said Friday. "It looks like we'll rest it for a week, then play catch for a week, then do a couple of bullpens and see how it feels."
