"I just reacted," he said. "I didn't want him coming into the bullpen, doing something stupid or crazy. I was just trying to help out security. I didn't see security."
It wasn't the first time Papelbon had seen that happen. He said fans have leaped into the Red Sox bullpen at Fenway Park.
"It's not anything new," he said.
So Papelbon just grabbed the fan and held him until security arrived?
"I put him in a sleeper hold," he said. "That's about it."
Did he say anything?
"He just went, 'Aggggh,'" he said, mimicking a choking sound.
