CENTEREACH, N.Y. (AP) _ A 7-year-old boy playing baseball in his backyard died after the ball struck him in the chest.

Ryan Blanco and his brother, whose name and age were withheld, were playing outside their Long Island home Sunday night while their parents were inside, police said.

His brother, who was about the same age, hit the baseball and it struck Ryan, who immediately collapsed, police said.

A neighbor started CPR, and paramedics continued it on the way to University Medical Center at Stony Brook, but the boy was pronounced dead shortly after arrival.

An autopsy was planned to determine the cause of death.
