My brother in the 70s was playing for a traveling baseball team. My dad was the manager. The power hitter showed up late, and my dad asked my brother to throw him batting practice. First pitch, line drive right back to my brother, who didn't react in time. Hit my brother square on the nose, and broke it in 3 places. My brother had emergency surgery later that evening, and plastic surgery 2 weeks later, 2 months later, he was back playing on the team.
