Since the Giants miraculous entrance into the 1951 World Series via Bobby Thomson’s pennant-winning homer, the Giants have had their problems the season after.
In 1952, the Giants finished second in the NL to the Dodgers.
In 1955, a year after winning the World Series with a four-game sweep over heavily favored Cleveland, the Giants finished third behind the Dodgers and Braves.
In 1963, a year after pushing the Yankees to a nail-biting Game 7 in the World Series, the Giants finished third behind the Dodgers and Cardinals.
In 1990, a year after getting swept in the Bay Bridge World Series, the Giants finished third in the NL West behind the Reds and Dodgers.
In 2003, a year after the seven-game defeat to the Angels in the World Series, the Giants won 100 games and breezed into the playoffs — where they were dumped by the Marlins.
And of course this year, one season after San Francisco’s first World Series championship, no postseason.
