This was the team's only season when they were named the Perfectos. The Robison brothers, who had just bought the team from original owner Chris Von der Ahe, changed the colors to red, the name of the team to Perfectos, and the name of the ballpark to League Park. The red color proved so popular that fans and sportwriters began referring to the team by the shade of red, Cardinal. The next season the team officially became the Cardinals.
The team benefited from a large number of players who were transferred to the team from the Cleveland Spiders, which were also owned by the Robison brothers. This led to the Spiders compiling the worst season in MLB history, losing 134 games. However, the Perfectos wound up finishing only 5th. The pennant-winning Brooklyn Superbas, who finished 18½ games ahead of St. Louis, benefited from a similar arrangement, as Brooklyn's owners also owned the Baltimore Orioles, allowing them to also transfer their better players into one team. After the 1899 season, such arrangements were outlawed in MLB, and both the Spiders and Orioles were among four teams eliminated from the league.
