ARLINGTON, Texas — Reigning AL MVP Josh Hamilton grabbed the foul ball that ricocheted into left field and tossed it into the stands, as he has countless times before. Shannon Stone, who was at the game with his young son, caught the ball but tumbled over a railing and plunged 20 feet onto concrete. The 39-year-old firefighter from Brownwood died at a hospital a short time later, the Tarrant County Medical Examiner’s Office said. Oakland reliever Brad Ziegler was in the visitor's bullpen in left-center field, not far from where Stone fell. When Stone was put on a stretcher, Ziegler said, the firefighter told his tenders that his son was "up there by himself" and asked them to check on the boy. "He had his arms swinging. He talked and was conscious," Ziegler said. "We assumed he was OK. But when you find out he's not, it's just tough."
