From a Tuesday press release from the Oakland Athletics:
Brandon McCarthy, who underwent head surgery last Wednesday after sustaining injuries from a batted ball in a game played at the Coliseum earlier that day, was discharged from California Pacific Medical Campus in San Francisco earlier this afternoon.
Dr. Peter Weber, the neurologist who performed the surgery at CPMC, and Dr. Allan Pont, A’s team physician, both felt that McCarthy had made an excellent recovery and could be safely released from the hospital.
Also in the release, McCarthy thanked everyone involved in his medical treatment, along with his teammates, fans, and everyone else who's expressed concern since he suffered the injury. According to the A's, McCarthy will remain in the Bay Area, recovering, for at least the next three weeks.
Since the game in which McCarthy was struck by the line drive hit by Erick Aybar, the A's have won four straight games and taken a small lead in the American League's Wild Card standings.
