Trivia: What team swept the Oakland A’s in four games in the 1990 World Series?
Boston Red Sox
San Francisco Giants
Correct Answer: Cincinnati Reds
So why is this answer correct? : As of 2021, there have been a total of 21 World Series sweeps. One of the most famous happened in 1990, when the Cincinnati Reds took the title in a four-game sweep against the defending champion Oakland A’s, who had won in a four-game sweep of the San Francisco Giants the previous year. More than three decades after Cincinnati’s surprise victory — the franchise’s fifth and most recent World Series win — fans still refer to that Reds team as “the Big Red Machine.”
