Unpredictable moments define every sports competition. No athlete or team with an unbeatable reputation can prevent an unexpected underdog win that shocks the entire world. Throughout the last 10 years, the world has experienced unprecedented shocking events in sports history. The following list grates the ten most vital sports upsets that occurred throughout the previous decade both in championships and Olympic competitions.
No compilation of sporting upsets would be complete without mentioning Leicester City’s stunning Premier League title victory. They were relegation candidates at the start of the 2015-16 season, but they upset all predictions to claim the title. With Jamie Vardy leading the charge up front and N’Golo Kanté dominating the midfield, Leicester pulled off one of the greatest shocks in footballing history.
The U.S. Women’s National Team had dominated soccer for years on the international stage, but at the 2021 Tokyo Olympics, they were stunned by Canada in the semifinals. A late penalty kick by Jessie Fleming sealed the fate of the U.S., a disappointing loss for a team that was a heavy favorite to win gold.
In the history of March Madness, a No. 1 seed had never lost to a No. 16 seed—until the University of Maryland, Baltimore County (UMBC) stunned Virginia in 2018. The Retrievers dominated the game, winning 74-54 and making NCAA history in the process.
Tiger Woods completed one of sport’s finest comeback tales at the 2019 Masters. Woods claimed his fifth green jacket after years of injury and setbacks and the golf world was left stunned. The win was a reminder of why Woods is among the best the sport has ever witnessed. For people who followed golf news at the time, it was still relevant; they may even recall seeing discussion of the bet 365 bonus code while reading previews and predictions of the tournament, because big events have a way of drawing in sports fans even more.
Serena Williams was the heavy favorite entering the 2018 U.S. Open final, but Naomi Osaka had other plans. In a match that was as much about controversy and drama as tennis, Osaka remained composed and captured her first Grand Slam title, setting her on the path to tennis superstardom.
The St. Louis Blues were at the bottom of the NHL standings in early 2019. By June, they were lifting the Stanley Cup for the first time in franchise history. Led by rookie goaltender Jordan Binnington and a determined core, the Blues completed one of the most improbable turnarounds in NHL history.
While not in the last decade, this upset deserves an honorable mention as it left a lasting impact. The USA boasted a star-studded roster with LeBron James, Dwyane Wade and Carmelo Anthony when they came into the 2006 FIBA World Championship. However, Greece, led by Theo Papaloukas, executed a perfect game plan in ousting the Americans 101-95 in the semifinals, demonstrating to the world that international basketball was catching up with Team USA.
The Atlanta Falcons were ahead of the New England Patriots 28-3 in Super Bowl LI, a lead that seemed insurmountable. But Tom Brady and the Patriots staged the greatest comeback in Super Bowl history, rallying to tie the game in regulation and winning 34-28 in overtime. It was one of the most shocking moments in NFL history.
Ronda Rousey was the face of women’s MMA and was seemingly invincible. That is, until Holly Holm stunned the world with a head-kick knockout at UFC 193. Not only did the upset topple Rousey, but it changed the face of women’s mixed martial arts forever.
The 2023 NBA Playoffs saw the No. 1-seeded Milwaukee Bucks lose to the No. 8-seeded Miami Heat in the first round. Giannis Antetokounmpo and the title favorite Bucks were eliminated in five games, proving that anything can happen in the playoffs.
No one expected Croatia to advance very far in the 2018 FIFA World Cup, but they shocked the world by making it to the final. Led by Luka Modrić and a determined team, Croatia defeated football powerhouse countries like Argentina and England on their way to the finals, where they played France. They may have finished as runner-up, but their rags-to-riches story is one of the biggest upsets in World Cup history.
Simone Biles, the widely regarded greatest gymnast of all time, was set to dominate the Tokyo Olympics. Instead, she pulled out of several events, citing mental health issues, leaving the sports world stunned. Her withdrawal led to discussions regarding the well-being of athletes and the issue of mental health in sports and it was one of the most shocking moments in Olympic history.
Upsets in sports are what make the games so thrilling. No matter what the odds are, there’s always a chance for an underdog to rise and fell a giant.
