A fan was struck by a line-drive foul ball and taken away on a stretcher in the first inning of Sunday's game between the Chicago Cubs and Atlanta Braves at Wrigley Field.
Kyle Schwarber lined a foul ball just beyond the camera well on the first base side, striking the fan. Cubs first base coach Brandon Hyde reacted by putting his hands on his helmet after he saw the fan get hit.
The game was briefly stopped as fans and ushers waved for medics.
The woman was transported to a hospital, according to the Chicago Cubs. Team officials said she was conscious when transported.
"It's awful, pay attention," Joe Maddon, the Cubs' manager, said. "Those are wonderful seats, probably paying a lot of money for them. I see people turning their back to the action. You can't do it."
Schwarber tweeted that the woman was in his "thoughts and prayers" Sunday evening.

On Friday, a female fan in Detroit was injured by a foul ball behind the Tigers dugout.
Earlier this year, a Massachusetts woman was seriously injured after being struck in the head by a broken bat in the stands at Fenway Park. Last month, an Oakland Athletics season ticket-holder asked a federal court in a lawsuit to order Major League Baseball to extend the safety netting at its ballparks the entire length of the foul lines.
After the incident at Wrigley Field, Maddon advised fans to always keep an eye on the game to avoid future incidents like this one.
"When you're at the ballpark, watch what's going on," Maddon said. "Every time a ball is pitched, you look, you look, then you can talk. When my family is there, I insist that they pay attention to what's going on."
