That was a great story on Nomar, Davis and Sizemore.
Similar type scenario with Herb Score--amazing first two years until Gil McDougald hit him in the face with that famous line drive.
What I never realized was how torn up McDougald was that it may have caused him to lose the desire to play.
https://sabr.org/bioproj/person/herb-score/"McDougald was an emotional mess after the incident. He was put at ease somewhat after a long conversation with Anne Score, Herb’s mother. Nancy, his fiancée, rushed to Cleveland when she heard the news. Score was hospitalized for three weeks, until May 28. Although he looked fit and fully recovered, Score was months away from the playing field. He sympathized with McDougald: “I talked to Gil and told him it was something that could happen to anyone. It’s just like a pitcher beaning a batter. He didn’t mean it.”
McDougald lost his desire to play baseball and retired after the 1960 season. Whether or not the incident with Score was responsible, the Yankee’s average dropped from .289 in the seven years before 1957 to .253 from 1957 through 1960."
