Stone, 38, saved a woman who nearly choked to death during a game at Yankee Stadium Tuesday, according to the New York Daily News.
Stone, a member of the Connecticut National Guard, jumped into action, performing the Heimlich maneuver on her.
"Basically, I just went down there and told the guy working on her that I'm an Army medic," Stone told the Daily News.
"I stepped behind her, gave her about five or six abdominal thrusts and eventually she coughed up whatever she was choking on."
The woman Stone saved, Terry Weiss, is the wife of a prominent Bronx rabbi, according to the paper. She choked on a piece of kosher London broil, the paper reported.
Toby Weiss was evaluated by medical personnel at Yankee Stadium and returned to thank Stone. "I said to him, 'I'm a big Yankee fan, but I really didn't want to die in Yankee Stadium,'" she told the paper.
Stone was at the game with his brother Jamie, an Army soldier on leave from duty in Afghanistan.
The Yankees rewarded the hero by moving him and his brother to the first row of the Legends section, seats that normally go for $1,250, and gave him Yankees gift bags, the Daily News reported.
