Kerry Wood, who was supposed to work on back-to-back days for the first time this spring, had to be scratched from Wednesday's appearance because of back spasms.
"Look, we do have one setback with Kerry today -- his back is really, really stiff and he's not going to be able to pitch today," manager Lou Pineilla said. "It has nothing to do with his shoulder, or elbow, it's just with his back. He went to see a doctor, and hopefully we'll get him out there (Thursday) or the next day." Piniella wants Wood in the closer's role, but it's unclear if he'd hand him the role without him having pitched on back-to-back days first.
