Bugs Hartley had been a well known character in baseball for some years. He had gained his nickname from his erratic habits. He had never been any too strong mentally, and his addiction to liquor had still further contributed to throw him off his balance. But he had been a remarkable pitcher, with a throwing arm that made up for some of his mental deficiencies, and had played in several major league clubs. For some years he had been a member of the Giants, and was still a member when Joe joined the team. His vicious habits and utter failure to obey the rules of discipline had made him a thorn in his manager's side, but McRae had tolerated him because of his unusual skill in the box.
