A Royals fan suffered a serious head injury when she was struck by the broken bat of Angels outfielder Torii Hunter. In the fifth inning of Thursday's game, the head of Hunter's maple bat snapped off, flew into the stands and struck Sue Cooney, 64, near the right eye. The Kansas City Star has reported that Cooney was hospitalized and will require facial surgery. "I don't think I got jammed," Hunter said. "I hit it pretty good and it blew up." Maple bats have been popular with major league players since Barry Bonds popularized them a decade ago. Other players still use ash bats, which tend to crack rather than splinter, according to studies. The swing that broke Hunter's bat produced a single to medium-deep center field.
