A history of baseball and chewing tobacco in Slate. How things change (emphasis added):

The sudden decline of former batting champion and career .308 hitter Michael “King” Kelly–he
hit just .189 in 1892 and was only able to play 78 games–was attributed
to his longtime habit of smoking while patrolling the outfield.

Never mind the chaw. Can you imagine Johnny Damon, chilling out in left field, with a cigarette dangling from his lip? How does a guy shag flies while smoking?
