No ... Jackie hit home runs in the 1952 and 1956 World Series but not in the 1955 World Series.
Yes, once. And I was there!
Jackie's final MLB home run came in Game 1 of the World Series against the New York Yankees at Ebbets Field.
Jackie Robinson won a World Series with the 1955 Brooklyn Dodgers.
Because hes black. Note that the person that said the previous statement is too stupid to know how to spell the simple contraction "he's." This moron is also unaware that Jackie Robinson has been dead for quite a while, meaning it is incorrect to say that "He's black" -- the only intelligent statement would be "He WAS black." Oh, and BTW, Robinson got the nickname because he was quite adept at stealing bases -- he's one of the few players to ever steal home in a World Series game.
Chase Utley, and Reggie Jackson have the most home runs in a single World Series with 5. Utley hit 5 home runs in the 2009 World Series, and Jackson hit 5 home Runs in the 1977 World Series.
Reggie Jackson holds the record for most home runs in a World Series with 5 hit in the 1977 World Series.
Babe Ruth hit 15 home runs in 41 World Series games and 129 World Series at bats.
The 2010 World Series has yet to occur.
