Forgive Cubs manager Dale Sveum for wanting to see the July 31 non-waiver trade deadline pass without major headlines about his pitching staff. No manager would want to see such a starting staff broken up. ''You think about that a lot,'' Sveum said Sunday soon after the latest masterful job by Matt Garza against the Arizona Diamondbacks. ''You don't dwell on it, but a streak like this, you don't want to lose pieces of the rotation.''
