Chapman, of course, was not wearing a batting helmet, something that became more prevalent in the 1940s. Batting helmets became mandatory for all players who came in the league 1956 or later. Of course, the rule has included first and third base coaches since 2007. Chapman was only 29, in the prime of what had started out as a good MLB career. As a SS, he led the AL in runs scored and walks with 84 in 1918. The Indians would go on to win the World Series in 1920, considering Chapman a part of it. As the team had dedicated its season to him, it seemed fitting that he was awarded a full World Series share as well as a World Series ring.
