Cubs' reliever Kerry Wood pitched to batters on Sunday but probably won't return until later this week because of an injury to his right index finger, according to The Associated Press. He has been sidelined since July 11. "He felt OK, looked a little rusty -- that's to be expected," Manager Lou Piniella said. "The important thing now is to see how he feels tomorrow. After that, I'll put together a schedule to get him back pitching."
