NEW YORK — The New York Yankees are expanding netting to protect seats behind each dugout and for five sections past down both foul lines, a decision announced after several fans were injured last year.

A boy was struck on the head by a portion of Chris Carter’s broken bat at Yankee Stadium on May 25, and a fan sitting beyond the first-base dugout was hit by a 105 mph foul ball off the bat of Aaron Judge on July 25. A young girl was injured by a 105 mph foul ball off the bat of Todd Frazier on Sept. 20 and was taken to a hospital.

Team officials said Wednesday that green netting, designed to minimize visual impact, will rise 9 feet above each dugout but the bottom 3 feet will be retractable and pulled up during batting practice to allow fan interaction with players.

Beyond the dugouts, nets will rise to about 5 feet above the wall, which is 8 feet above the field surface. The Yankees said the system is called Dyneema fiber Ultra Cross 1.2 millimeter-wide knotless netting and will be in front of seats until the stands are parallel to the foul lines.

Major League Baseball issued recommendations for protecting netting or screens in December 2015, encouraging teams to have it in place between the ends of the dugouts closest to home plate. The Mets extended netting beyond the outfield ends of the dugouts last summer, and Boston, Cincinnati, Cleveland, Colorado, Detroit, Milwaukee, Minnesota, San Diego and Seattle are among the teams that have said they intend to have expanded netting this year.
