An eight-year-old boy suffered a cardiac arrest after being hit in the chest with a ball during a baseball game.
The child was batting during a little league match in Rhonert Park, California, when the ball hit him in the heart. Two off-duty paramedics rushed to his aid.
Another player, 14-year-old Trenton Starrett told ABC news that he saw the incident close up.
"I was right behind the plate and this kid got hit in the heart with the ball," he said.
The little lad managed to take a few steps toward first base before collapsing. Off-duty medics Dan and Susan Farren raced to help him and performed CRP until the emergency services arrived.
The boy, whose name has not been revealed, was recovering at Oakland Children's Hospital where he is due to undergo more tests.
Aaron Johnson, one of the a directors for Cal Ripken Baseball in Rohnert Park, said the boy who threw the ball was devastated by what had happened and had been in touch with the family.
"He's doing better. Every time he hears his friend is getting better, it takes the burden off of him a little bit," Mr Johnson told the Press Democrat. "A pitcher's biggest fear is hitting someone."
League officials are now considering whether to keep a defibrillator on the grounds for such incidents.
The boy's family are not giving any interviews to the media, but Mr Johnson has spoken to them and says they regard Dan and Susan Farren as 'heroes'.
