The Chicago White Sox will extend protective netting to both foul poles this summer.
The decision comes a week after a woman at Guaranteed Rate Field was struck in the head by a foul ball and hospitalized.
According to sources, owner Jerry Reinsdorf spearheaded the plan. Officials from other teams expect it to have a cascading effect throughout the league.
One source with knowledge of installing netting believes other teams could retrofit their stadiums before the end of the season.
