1919 Philadelphia Athletics season

The 1919 Philadelphia Athletics season involved the A's finishing last in the American League with a record of 36 wins and 104 losses. It was their fifth consecutive season in the cellar after owner-manager Connie Mack sold off his star players.

Philadelphia led the AL in fewest runs scored and most runs allowed, and they did so by wide margins. Their team ERA was 4.26, nearly a full run higher than the second worst team in the league that year. The A's team batting average of .244 was the lowest in both leagues. The pitching staff pitched only one shutout in the entire season.

In July 1919, a newspaper reported, "Veteran Harry Davis has been coaxed out of his retirement and has been made assistant manager of the Athletics." Although Connie Mack was the team's manager, the report said, "Mack hereafter will devote most of his time to business affairs of the club" and that the understanding was that Davis "really is in full charge of the team."
