The Spiders were tanking.

[Verginius Rufus]

The earlier Major League Baseball season was 154 games. It's now 162 games.

When Roger Maris hit 61 home runs, beating Babe Ruth's record of 60, a lot of people wanted there to be an asterisk next to his name because he had not hit the 61st home run in the first 154 games of the season.

[Vigilanteman]

Cleveland Spiders, 1899, kind of doesn’t count because the team was sabotaged by their owners. They didn’t lose fair and square.
