Giants general manager Brian Sabean has flatly ruled out a trade for pitcher Roy Halladay. He denied reports that San Francisco had been considering Halladay, and added that most of their trade talks have centered around improving their offense. "We don't want to deplete our assets when there's another route we need to go," Sabean said. "Simply put, (Jonathan) Sanchez and Sadowski have to step up. Each day Randy doesn't pick up a baseball, the longer it looks like he won't be back any time soon. We should have a lot more information on him in a couple of days."
