1900 Chronicle Telegraph Cup

The Chronicle Telegraph Cup was held just once, in 1900, and was sponsored by the Pittsburgh Chronicle Telegraph, a newspaper in the hometown of the National League's second-place finisher, the Pirates. It pitted the Pirates against the first-place Brooklyn Superbas in a best-of-five postseason series. The Superbas won the series, 3 games to 1.
