Is it World Series or World’s Series?
The name of the Major League Baseball (MLB) championship is the World Series (with no apostrophe). “World” is a singular noun, and it’s not possessive. People sometimes mistakenly write “World’s Series,” because the event used to be called the “World’s Championship Series.”
