It is without question one of the most iconic moments in baseball history and there was no way it wouldn't be the last member of this list.
In Game 1 of the 1955 World Series, Robinson stole home in the top of the eighth inning as his team trailed 4-6.
The article that I linked to in the introduction said that the most significant steal of home for Robinson was his first one as a 22-year-old.
"Robinson's most famous steal of home came in the '55 Series, but his most significant was his first, which occurred in June of his revolutionary rookie year with the Dodgers. Earlier that season Pirates lefty Fritz Ostermueller had hit Robinson with a pitch, raising the ire of Robinson's teammates. In a rematch with Ostermueller on June 24, the Pirates and Dodgers were tied 2-2 in the fifth when Robinson reached base on a fielder's choice and was singled to third by Carl Furillo, who quickly stole second. With Ostermueller no longer concerned about a double steal, Robinson exacted his revenge, swiping home with what would prove to be the decisive run in the Dodgers' 4-2 victory. The steal spoke volumes about Robinson, who not only had the talent to break baseball's color line but the combination of talent, temperament, and timing to hit his detractors where it hurt, on the scoreboard. He would steal home 19 more times in his career, including that famous swipe against the Yankees, which remains the last straight steal of home in World Series history."
I'll take the last straight steal of home in the World Series though, as it is one of the most memorable and replayed moments in the game's history.
You really can't go wrong with either of them.
