2. 2005 Champions League Final
Liverpool were 3-0 down after the first 45 minutes in Istanbul against AC Milan in the 2005 UEFA Champions League final. They had definitely not been one of the favorites for the trophy from the start of the competition and kept defying the odds to make it all the way to the final including an amazing last second goal from Steven Gerrard against Olympiacos to get them out of the group stage.
All of that appeared to be in vain after Paulo Maldini scored from an Andrea Pirlo cross within the first minute before Kaka took over the game to set up a Hernan Crespo double.
Many fans left the stadium at half time as Liverpool were beaten. They lost both Harry Kewell and Steve Finnan to injury by half time to compound their woes. To score 3 goals in one half against what was the best defensive team in the world at the time. Nonetheless Rafa Benitez's men began to fight back and the greatest 6 minutes of Liverpool's season brought them to a penalty shootout where second choice goalkeeper, who had stood in for most of the season, Jerzy Dudek stopped the mercual Andrei Shevchenko's penalty to win them their fifth Champions League title.
Led by David Ortiz's amazing hitting from home plate, the Sox won the fourth game, after being blown out 19-8 in the third matchup, with a Big Papi walk off Home run.
With runners on 2nd and 3rd Ortiz stepped up to the plate again in game 5. The Red Sox needed one final run but Yankee's pitcher Esteban Loaiza had the Sox on the Boston based team on their final out. Ortiz hit a single to the center to give the Yankees a second successive victory.
A low scoring affair in New York resulted in a 2 run victory for the Red Sox that primed game 7 matchup that would decide if this was to be the greatest ever comeback in Baseball.
David Ortiz set the team in motion with a 2 run homer in the first inning and Boston never looked back in the final game. They won by 10-3 completing the most improbable victory in Baseball history.
