PITTSBURGH—At press time, Cubs manager Lou Piniella's attempt to remove starting pitcher Carlos Zambrano from tonight's game against the Pittsburgh Pirates had entered its fifth hour, with Zambrano refusing to be replaced by left-handed relief pitcher James Russell. Piniella reportedly emerged from the dugout at approximately 8:45 p.m. to make the pitching change, a move that prompted Zambrano to wave the reliever back to the bull pen. Zambrano then refused to give Piniella the game ball, and in the past two hours the All-Star pitcher has, with the manager standing on the mound directly next to him, attempted to throw several pitches to current batter Lastings Milledge. At 1 a.m., Zambrano was overheard saying, "I'll stand out here until dawn if I have to." Home plate umpire Laz Diaz's efforts to get the pitcher and manager to wrap it up have thus far been unsuccessful, though Diaz is now considering paying a second visit to the mound. The Pirates currently lead the Cubs 14-2.
