Carlos Zambrano threw 7 1/3 hitless innings Monday night and helped himself by driving in four runs, including three on his fifth career home run, to lead the Chicago Cubs to an 8-0, one-hit victory over the Houston Astros. "It was a high school game for him tonight," Cubs center fielder Juan Pierre said. "He was the best pitcher and hitter on the field. Four ribbies -- it takes me two months to get four ribbies."
