1.The Miracle on Ice
The 1980 Olympics will forever be remembered as the greatest Olympics in American Ice Hockey. A group of untested college and amateur athletes represented the United States in the semi finals of the Ice Hockey tournament where they met the Soviet Union team that had won 8 of the past 9 gold medals in the event. The Americans came into the tournament as the 7th seeds of 12 teams and had lost to the Soviets 10-3 in their previous matchup that year. In what will always be referred to as a 'miracle' the USA edged out a thrilling encounter that finished 4-3.
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.
3.2004 American League Championship Series
In 2004, the Boston Red Sox fell down by 3-0 against their long time rival New York Yankees in the American League Championship Series. No team had ever come back from 3 down in a series to win it. The Red Sox knew that and their motto fittingly became why not us?
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.
4.2010 All Ireland Hurling Final
The build up to this game began 4 years previously.
From the moment Kilkenny won the 2006 All Ireland Hurling final in Croke Park they didn't relinquish their stranglehold on inter county hurling. Kilkenny won an unprecedented 4 titles in a row and were gunning for their fifth title in 2010. The thing about Kilkenny's hurling team was that they weren't just beating teams. They were annihilating them.
While they would never admit it, many teams felt it was an achievement to just be able to compete against Kilkenny when they were on form. They had a second team that was probably better than 90% of the other hurling counties in Ireland.
The Cats made it to the final in 2010 once again and found a talented Tipperary side waiting for them once again. Tipperary had lost a thrilling game the previous season by 5 points but thanks to a hat-trick from Lar Corbett Tipperary beat their rivals from a season ago. The nature of the victory was the most shocking aspect of the game as a team that had for so long been blowing opposition out was convincingly manhandled in the final loosing in the end by 8 points and conceding 4 goals.
