The Giants got mostly what they wanted Saturday from right-hander Jeff Samardzija: hope. Results, they realized, must wait for another time. Samardzija performed about as well as could be expected after returning from right shoulder tightness, which had sidelined him since May 29. He showed hints of the velocity and command that distinguish him when he's at his best, though he absorbed the loss in the Giants' 3-2 defeat at the hands of the Cardinals.
