I used 1903 only because that was the year of the first World Series. I know there were other teams before that.

I was unaware of some of those team nicknames, though. The Boston Americans were also the Pilgrims. The Phillies were the Blue Jays for a time (in the 1940s, I think; the owner rightly thought the name "Phillies" was trite). The Dodgers were the Robins when Bill Wambsganss made the unassisted triple play against them in the World Series (1920). The Cleveland Spiders became the Naps, and in 1915 the owner let the fans choose the nickname, and they selected "Indians," which I had always thought was to honor their recently deceased former star Chief Sockalexis, but apparently that's disputed.

I remember when the Dodgers were "Dem Bums" and headlines like "Bums Win" or "Bums Mugged in Philly" would grace the back cover of the NY Daily News.

Yes, Eddie Mathews is the answer. Many people guess Warren Spahn.
