The Chicago Cubs' organization has begun a $1.5 million overhaul of Wrigley Field that includes the removal of nearly 15 million pounds of dirt. The Chicago Sun-Times said Saturday that as part of the massive field overhaul, workers have begun transplanting dirt from Wrigley Field to two DuPage County dumps to make way for a new drainage system. Chicago White Sox groundskeeper Roger Bossard said the new state-of-the-art system will lessen Cubs' head groundskeeper Roger Baird's worries about increased rainfall in Chicago. "He's going to be able to sleep at night when he gets that one inch of rainfall," Bossard said of the construction effort.
