"The most famous injury that was similar came in 1957, when Cleveland Guardians phenom Herb Score was struck in the face by a line drive off the bat of the New York Yankees' Gil McDougald. The blow broke several bones in the face of the 24-year-old left-hander and left him bloodied.
Score returned late in the 1958 season, but fearful of being hit by another batted ball, his pitching motion was altered, and he was never quite the same. His velocity dropped and he became prone to injury as a result of the changed motion."
