Underdog victories happen across the pond in North America, too, including in the "provincial" sports.

1. Major League Baseball -- 2004-- Boston Red Sox upset New York Yankees in 7 games for first playoff victory over their archrivals since 1918. That's 86 years!

2. National Football League -- 1991 -- New York Giants defeat the heavily favored Buffalo Bills 20-19 in the Super Bowl. This is the famous Whitney Houston Game around the time of Operation: Desert Storm. It's also the first of 4 consecutive Super Bowl defeats for the Bills.

3. National Hockey League -- 1984 -- Edmonton Oilers defeat New York Islanders to capture the first of 5 Stanley Cup Championships over 7 seasons. The Oilers ended a 4-year dynasty to begin their own dynasty. One season earlier the Oilers were swept by the same Islanders team. For the Oilers to win, they had to end the still-record for consecutive playoff series won streak at 19. It took a dynasty to beat a dynasty, but no one saw that at the time.
