Abner Doubledeal, the owner of the Ultimate Robot Fighting League in "Raging Bender", has, by this episode, become the owner of the New New York Mets. His name references Abner Doubleday, who, long after his demise, was widely believed to be the inventor of baseball. A.G. Spalding, the sporting goods magnate, who also originated the financial ruin of the game's first league, the National Association, hand-picked and headed a commission composed primarily of business associates to proclaim Doubleday as baseball's creator in 1905.

Leela's uniform number, 7/8, references Eddie Gaedel, a midget signed to the St. Louis Browns in 1951 as a publicity stunt, and the only player to wear the number 1/8. In his only major league plate appearance, Eddie was told not to swing, and walked on four pitches, making it as far as third base.
A parody of the Rainbow Man can be seen at the opening shot of Leela's first game where he is holding up a sign that says "Glorx 3:16", a to the "John 3:16".

Leela, the veteran player, throws Jackie, the aspiring player, her towel. This is a parody of a "Mean" Joe Greene Coca-Cola commercial, in which the pro similarly, albeit more accurately, gifts a young fan.
The Citgo sign in the background at 30th century Fenway Park is often seen on 20th century televised Boston Red Sox games.
