Work crews have begun extending the protective netting to the foul poles at Guaranteed Rate Field, a step the Chicago White Sox are taking following a couple of high-profile injuries this season.
The White Sox say the majority of the work should be completed Wednesday and the netting will be in place when the team returns home July 22 to host the Miami Marlins.
The White Sox became the first major league team to take the step after a liner by Cubs outfielder Albert Almora Jr. struck a 4-year-old girl in Houston in May. A woman was hit by a foul ball off the bat of White Sox slugger Eloy Jiménez in Chicago on June 10.
Commissioner Rob Manfred has said extending protective netting down foul lines is a ballpark-to-ballpark decision because of differing configurations. Major League Baseball mandated ahead of the 2018 season that netting extend to the far end of each dugout.
The Pittsburgh Pirates, Texas Rangers and Washington Nationals are among the other teams that have announced they'll extend netting.
