The most memorable moment in baseball history

[Eric72]

There have been innumerable stories in the 150+ year history of professional baseball.

Some of them involve a stretch of time measured in years: Babe Ruth's career, the existence of the Negro Leagues; the Yankees' five straight championships. These are interesting and significant. They are not moments, though.

Other stories focus on a single season or portion thereof: Christy Mathewson's performance in the 1905 World Series; the dominance of the 1927 Yankees; the National League pennant race in 1908. These stories are wonderful; however, they're not about moments, either.

What I'm looking for are moments in time, a minute at most, that endure to this very day.

A few that come to my mind are:

Bobby Thomson's "shot heard 'round the world."
Jackie Robinson takes the field for the first time.
Babe Ruth's "called shot."
"Merkle's Boner."
"Kelly now catching."
Kirk Gibson's home run in Game 1 of the 1988 World Series.
Pete Rose collides with Ray Fosse.

There are many, many more.
