"I feel for the lady," Pirates manager Clint Hurdle said after the game. "Lot of concern there, and she wasn't getting moved any time soon, and for all the right reasons. Those things are out of your control."
The fan, who was placed on a stretcher and carefully carried up the stadium steps, received a chorus of encouraging applause from the crowd.
"During the top of the second inning a female fan was struck in the head with a foul ball," the Pirates said in a statement updating her condition. "After initial treatment by PNC Park and Pittsburgh EMS personnel, she was placed on a stretcher, moved to a nearby ambulance and brought to the hospital for further treatment. She was conscious and alert at the time of transport, graciously thanking her caregivers while giving a 'thumbs up' gesture to nearby fans.
"Our thoughts and prayers are with her. We will share additional information as it becomes available."
Burnett saw it unfold and called over to first-base umpire Joe West, the chief of the umpiring crew working the game. They both signaled to plate umpire D.J. Reyburn, who signaled for stoppage of play.
"Something I had never been a part of," Burnett said. "When West came over, he made a great point: 'We care. We care about our fans as much as about anything else. So whatever I had to do [with the delay], I was willing to do."
While the fan, whose identity was not disclosed, received medical care, players from both teams waited patiently and hoped for the best. Pirates catcher Francisco Cervelli walked to the screen and checked on the woman's condition, concern evident on his face.
"We're out there doing our thing, someone here watching the game, sad that happens," Burnett said. "Our thoughts and prayers are with her, for sure. Crazy that it happens, but we're human beings, too -- we feel, we see. And that's very unfortunate."
