The Philadelphia Keystones (also known as the Keystone Club of Philadelphia) were a professional baseball franchise. In 1884, they were a member of the short-lived Union Association. The team was owned by former player Tom Pratt.[1]
The Keystones were managed by catcherFergy Malone and finished in eighth place in the 12 team league with a 21–46 record. Their top-hitting regular was left fielder / infielderBuster Hoover, who batted .364 with a slugging percentage of .495, and their best pitcher was Jersey Bakley, who was 14–25 with an earned run average of 4.47. Their home games were played at Keystone Park. Jack Clements, who played for 17 seasons and was the last (and virtually the only) left-handed catcher in major league history, made his big-league debut with the Keystones.
Like several other teams in the Union Association, the Keystones did not make it through the entire season, folding after the game of August 7. The entire league ceased operations after 1884, its first and only season.
1860s
There was an amateur or semi-pro Keystone club in Philadelphia during the 1860s. They generally played their games at the same ballpark as the better-known Athletic ball club. The 1884 team revived the old club name, and both names reference Pennsylvania, "The Keystone State".
