1990 Major League Baseball postseason

In the American League, the Boston Red Sox reached the postseason for the third time in five years, and the Oakland Athletics made their third consecutive appearance.

Both teams would meet in the postseason again in 2003, where the Red Sox defeated the Athletics in five games in the ALDS before falling in the ALCS.

The Reds would return to the NLCS in 1995, but were swept by the eventual World Series champion Atlanta Braves.

In what is considered to be one of the biggest upsets in World Series history, the Reds shockingly swept the Athletics to win their first championship since 1976 and their fifth overall.

Game 2 was the only contest of the series to go into extra innings, and the Reds prevailed thanks to a walk-off RBI single from Joe Oliver.

In Game 4, Rijo, who was on three-days rest, along with Myers, helped preserve a one run Reds lead to complete the sweep and clinch the title.

This would be the last postseason appearance by the Reds until 1995, where the team was swept by the eventual World Series champion Atlanta Braves in the NLCS.

The Athletics would return to the postseason in 1992, only to lose to the eventual World Series champion Toronto Blue Jays in six games in the ALCS.

This marked the first year of a four-year agreement with CBS to televise all postseason games nationally in the United States.
