The father of a young girl who was struck in the face by a line drive at Yankee Stadium last month spoke publicly for the first time this weekend about the episode, describing in chilling detail the girl’s injuries and urging the Yankees to take action to extend the protective netting in their ballpark.

He made his remarks in an interview with The New York Times, and in a written statement that he provided. And on Sunday afternoon, the Yankees did act. They issued a statement that said they would “significantly expand” the netting at both Yankee Stadium and the team’s spring training ballpark in Tampa, Fla., in time for the 2018 season.

The Yankees’ statement came shortly before the father’s interview with The Times was published. In his recollection of the episode, the father, Geoffrey Jacobson, described the horror of walking into a hospital room to find his daughter, who will turn 2 this week, connected to tubes and machines. Her eyes were swollen shut, she had multiple facial fractures — including those of her orbital bone and nose — and doctors were monitoring the bleeding on her brain, fearing that it might lead to seizures.

And on her forehead, he said, was an imprint left by the stitches of the baseball that hit her.

Jacobson, who did not want his daughter’s name to be made public, said she arrived home Sept. 25 from NewYork-Presbyterian/Columbia hospital, five days after she was injured in an afternoon game while sitting behind the third-base dugout with Jacobson’s parents and her 4-year-old brother.
