Trivia: What was the name of the first professional baseball team?
Louisville Grays
Cincinnati Red Stockings
Hartford Dark Blues
Boston Redbirds
The correct answer is Cincinnati Red Stockings
So why is this answer correct? : The Cincinnati Red Stockings became the first fully professional baseball team in 1869 (though other amateur teams had secretly paid some of their members prior to that). Named for the red knee-high socks the players wore, the Red Stockings played their first game on May 4, 1869. The 10-person team went on to play — and win — 65 games that year.
