The biggest United States Championship upsets ever

Sports would mean a lot less without upsets. The favorites are supposed to win. That is the whole point of having favorites. The team with the better record, the bigger payroll, the Hall of Fame roster, the defending championship, the undefeated season, they are supposed to close it out and confirm what everyone already believed going in. That is the comfortable version of sports. The version that makes sense on paper and disappoints nobody except the people rooting for the other side. But every so often, the script gets thrown out entirely.

A team nobody believed in shows up to the biggest game of the year and plays like they have nothing to lose, because they genuinely do not. A backup quarterback goes toe to toe with the greatest of his generation and wins. A six-seed that barely made the tournament somehow beats the most electrifying team in college basketball on a buzzer-beating dunk. A franchise with no superstars holds a roster full of them to almost nothing for four straight games and walks away with the trophy.

These are the moments that people remember longer than any dominant dynasty performance. A 16-0 team losing the Super Bowl lives in memory more vividly than most championship wins. A perfect shooting performance from an 8-seed in the title game gets replayed and discussed forty years later. The Miracle Mets, the Helmet Catch, Valvano sprinting across the court looking for someone to hug, these are not just upsets. They are the games that remind you why you watch in the first place, why you stay until the final whistle, even when the result seems obvious, because sometimes it is not. This list ranks the ten biggest championship upsets in American sports history, from 10 to 1, with number 1 the upset that still feels impossible even after all these years.

10. Super Bowl XXXVI, 2002

New England Patriots def. St. Louis Rams, 20-17

Nobody took the Patriots seriously going into this game. The Rams were called the Greatest Show on Turf for a reason: a high-powered offense led by Kurt Warner that had been lighting up the NFL for two seasons. New England was quarterbacked by a sixth-round draft pick in Tom Brady, who had started the season as a backup. The Patriots played an almost perfect defensive game, held the Rams to 17 points, and then Brady drove the length of the field in the final minute to set up Adam Vinatieri’s game-winning field goal as time expired. Nobody realized it at the time, but that field goal was the beginning of the most dominant dynasty in NFL history.

9. 1988 World Series

Los Angeles Dodgers def. Oakland Athletics, 4-1

The Oakland Athletics entered this World Series as one of the most feared teams in baseball, built around Jose Canseco and Mark McGwire and a rotation that had steamrolled through the American League. The Dodgers were injured, short-handed, and not supposed to be competitive. Then Kirk Gibson, barely able to walk due to leg injuries and not expected to play at all, pinch-hit in the ninth inning of Game 1 and hit one of the most famous home runs in baseball history off Dennis Eckersley to win it. The Dodgers never let the series recover after that, winning in five games and producing one of the most improbable World Series results in the modern era.

8. 1995 Stanley Cup

New Jersey Devils def. Detroit Red Wings, 4-0

The Detroit Red Wings had finished the lockout-shortened 1995 season as the most dominant team in hockey, posting the best record in the league by a wide margin. The New Jersey Devils, built around a stifling defensive system called the neutral zone trap, swept them in four straight games, with the Wings scoring no more than twice in any game. It was one of the most one-sided Stanley Cup Finals in history against the most unlikely opponent, and it announced the Devils as a legitimate force in the sport for the decade ahead.

7. 2003 World Series

Florida Marlins def. New York Yankees, 4-2

The Yankees were the Yankees. The Marlins were a wild-card team built on youth and desperation. New York had every imaginable financial and historical advantage. Florida had Josh Beckett, who pitched a complete-game shutout on three days’ rest in Game 6 to close out the series in the Bronx and send the Yankees home empty-handed. The Marlins became only the second team in baseball history to win a World Series as a wild card, and they did it by walking into Yankee Stadium in October and shutting them out in the clinching game.

6. Super Bowl LII, 2018

Philadelphia Eagles def. New England Patriots, 41-33

The Patriots were defending Super Bowl champions. Tom Brady was 40 years old and had just come off arguably the greatest season of his career. The Eagles were starting a backup quarterback, Nick Foles, because Carson Wentz had torn his ACL in December. None of that mattered. Foles played the game of his life, caught a touchdown pass on a trick play that became one of the most replayed moments in Super Bowl history, and the Eagles won their first championship in franchise history. The combined 74 points and 1,151 total yards set Super Bowl records that still stand.

5. 1969 World Series

New York Mets def. Baltimore Orioles, 4-1

The Baltimore Orioles had won 109 games during the regular season. The Mets had been baseball’s worst franchise for most of their brief existence and were widely expected to lose badly and quietly. They did not. The Miracle Mets held the Orioles to a staggering degree over five games, got clutch hitting they had no business producing, and clinched their first World Series championship in front of a delirious Shea Stadium crowd. It remains one of the most complete championship upsets in baseball history and gave New York one of its most cherished sporting memories.

4. 1985 NCAA Final Four

#8 Villanova def. #1 Georgetown, 66-64

Called the Perfect Game for a reason. Villanova shot 22-for-28 from the field in the national championship game against Georgetown, a 78.6% field goal percentage that remains the highest in Final Four history. Georgetown was the defending national champion, had Patrick Ewing, and was a heavy favorite. Villanova was an 8-seed that had barely survived to reach the tournament. Coach Rollie Massimino had his team play a slower, deliberate style that took Georgetown completely out of its comfort zone, and Villanova made nearly every shot they took. It is still considered the most statistically improbable performance in championship game history.

3. 2004 NBA Finals

Detroit Pistons def. Los Angeles Lakers, 4-1

The Lakers had four future Hall of Famers in Shaquille O’Neal, Kobe Bryant, Karl Malone, and Gary Payton, assembled specifically to win a championship. The Pistons had no single star and were built entirely around defense, teamwork, and Chauncey Billups running the floor with calm precision. Detroit won the series 4-1, holding Shaq and Kobe to a fraction of what they normally produced, and it was not particularly close for most of the series. It is widely considered the greatest team of superstars to have been upset in NBA history, and it still gets cited as proof that a genuinely connected group of role players can beat a team of individual legends.

2. 1983 NCAA Final Four

#6 NC State def. #1 Houston, 54-52

Houston’s Phi Slama Jama was one of the most electrifying teams college basketball had ever seen, led by Clyde Drexler and Akeem Olajuwon and favored by everyone. NC State, a six-seed coached by Jim Valvano, had barely qualified for the tournament and spent most of the postseason grinding out wins in games they had no business winning. The championship game came down to a final possession, a desperation heave by Dereck Whittenburg, and a buzzer-beating tip-in dunk by Lorenzo Charles that gave the Wolfpack a 54-52 win. Valvano running across the court looking for someone to hug became one of the most iconic images in sports history.

1. Super Bowl XLII, 2008

New York Giants def. New England Patriots, 17-14

The Patriots had gone 16-0 in the regular season, the first team in NFL history to finish a full 16-game schedule undefeated. They had the league MVP in Tom Brady, the best receiving corps in football, and the greatest offense the game had ever seen statistically. The Giants were a wild-card team that had snuck into the playoffs. And then Eli Manning, pressured from every direction late in the fourth quarter, somehow broke free of a sack attempt, stayed upright, and heaved a pass downfield that David Tyree pinned against his own helmet with one hand while falling to the ground. Four plays later, Manning found Plaxico Burress in the end zone for the winning touchdown. The Patriots finished 18-1. It is the greatest upset in Super Bowl history and, by most accounts, the greatest upset in American championship sports, period.

Why these moments last

Every upset on this list did the same thing. It took the game away from the team that was supposed to have it and gave it to the team that refused to accept the script. The Miracle Mets, the Perfect Game, the Helmet Catch, NC State running onto the court, Villanova shooting nearly 80 percent in the biggest game of their lives. These are not just upsets. They are the games people tell their kids about, the ones that remind you why you watch in the first place.
