Has ANY team ever been up three games to none in a Championship Series or a World Series then proceed to lose the next four games and lose the series 4-3?

It seem to me it happened only one time in the history of baseball.
OK...... we felt bad for Boston fans...... decided to give ya one

On opening day this year at Fenway Park, the Red Sox were playing the Yankees and when they were introducing the players, the Red Sox fans, being the sensitive and caring people that they are BOOOOOOED every single Yankees player with the exception of Mariano Rivera, they gave him a standing ovation
LMAO..... in New York, if we don't like you, we throw batteries at ya while your standing in the outfield
