Oakland A's pitcher Brandon McCarthy suffered a skull fracture the other night at the Coliseum when he was hit in the head by a line drive. Fortunately, he is slowly recovering after surgery, but it was a frightening moment. I got to wondering why equipment manufacturers could not design a hat or helmet that would protect pitchers' heads without hindering their pitching. With the strong, lightweight materials now available, it seems like a literal no-brainer to come up with a comfortable skullcap for pitchers. It doesn't have to be a clunky helmet like batters wear. Any ideas out there, inventors? Put your thinking caps on.
