DURHAM, N.C. — Minor league pitcher Tyler Zombro was kept overnight at a hospital and remains in stable condition after being struck in the head by a line drive Thursday night, a frightening scene that prompted Triple-A Durham to suspend its game.

Zombro, a right-hander in the Tampa Bay Rays organization, was hit by a sharp liner. He crumbled to the ground, lay motionless for a moment face down, then began to convulse uncontrollably.
