Barry Bonds stayed home with the flu Saturday. The slugger missed spring training workouts because of the same illness that has affected several Giants players the past two weeks. Infielders Ray Durham and Lance Niekro also were sidelined by the bug, while right-hander Matt Morris and first baseman Rich Aurilia have returned to work after staying home earlier this week. Bonds made his spring debut Friday, going 0-for-2 with a strikeout and playing a shaky left field during the Giants' loss to the Brewers.
