1898 Cleveland Spiders season

The 1898 Cleveland Spiders finished with an 81–68 record, good for fifth place in the National League. After the season, the team's owners, Frank and Stanley Robison, additionally purchased the St. Louis Browns from Chris von der Ahe. Claiming disappointment in attendance in Cleveland, they transferred many of the Spiders' better players to the St. Louis team, which they renamed the Perfectos. The Spiders would fold after the 1899 season.
