The injury to Oakland Athletics pitcher Brandon McCarthy, who was struck in the head by a line drive off the bat of Angels shortstop Erick Aybar on Wednesday, was more serious than anyone initially believed, according to one doctor.
McCarthy, who walked off the field under his own power after being struck, suffered a fractured skull and underwent emergency surgery Thursday.
Dr. Geoffrey Manley, the vice chairman of neurological surgery at UC San Francisco, told the San Francisco Chronicle that bone fragments from a skull fracture can cut the middle meningeal artery, causing death.
"If you are not treated for this, you could die, but if you’re treated rapidly, you usually have a very, very good recovery," Manley said. "That is why people need to be evaluated promptly. Most patients who have this kind of injury return to a normal life. I have treated other athletes with similar injuries who have returned to playing sports."
