Following an ALCS victory against the Toronto Blue Jays in five games, the Oakland Athletics went on to sweep the San Francisco Giants in a World Series.
The A’s finished the year as the top club in the league, going 99-63, the highest mark in baseball history. They held a seven-win advantage over the second-place Kansas City Royals, who had the best record in the league.
Additionally, Oakland was unbeatable in the playoffs. With a commanding 4-1 victory against the Toronto Blue Jays in the ALCS, the Oakland A’s clinched the championship.

The Oakland A’s beat Toronto 6-3 in game two, with Mike Moore as the winning pitcher and Dennis Eckersley as the saver.
