One of the most exciting things about the Olympics are the unexpected upsets that occur. Depending on who you are cheering for, it could also be one of the most crushing things about the Games too.
A week of action is nearly complete in London and we have seen some unexpected things occur already. Here are some of the shocking upsets that have taken place at the 2012 Summer Games.
Missy Franklin wins gold in 100-meter backstroke
She wasn't supposed to finish first. That was reserved for the overwhelming favorite Emily Seebohm of Australia. The 200 was supposed to be Franklin's best chance for gold. A bronze, or just maybe a silver, was the medal expectation.
But after the turn Franklin found another gear and swam to an American record and Olympic gold. Her star was rising coming into the games, but the upset over Seebohm became her breakout moment. Franklin had arrived on the international scene.
It was not supposed to be her time yet, at least not in this event, but Franklin had other ideas and began her legacy a little sooner than anticipated.
Ryan Lochte fails to medal in 200-meter free
Lochte entered the Olympic Games as the next great American swimmer. Expected to have a Phelps-like performance in London. Those thoughts were shattered early. The most remarkable being the 200-meter freestyle race.
Winning gold would be tough, but medaling in the event was a no-brainer.
It quickly became apparent that gold was out of the question as Yannick Agnel crushed the field. But an unexpected dogfight was on for the other two medals and Lochte faltered—finishing fourth and coming up empty.
The hopes of Lochte putting on a Phelps-like performance and being a big star were dashed. He is a fine swimmer, but it puts into perspective how good Phelps is and how difficult what he did was.
Jordyn Wieber fails to make all-around finals
Wieber was one of the biggest hopes for the US women's gymnastics team. Unfortunately, a few errors here and there and she found herself outside of the finals.
She was the defending world champion and one of the favorites. Wieber not making the finals was a big upset, but no one beat her other than herself.
What makes it more crushing is that these Olympics are most likely her last. The career span for a gymnast is not very long and at 17 her career is nearly over at the elite level. Failing to make the finals at the Olympics, the I-Ching of gymnastics, was brutal to watch.
Great Britain defeats Brazil in women's soccer
Women's football has never hit big in England, but as the host country the stadium was packed and loud for their match against Brazil, a gold medal hopeful.
Just minutes in to the match Steph Houghton shocked Brazil and put Great Britain out front. The result would hold and they would come away with a shocking victory over the Brazilians, and the top spot in the group.
It could be a watershed moment for women's soccer in Europe. Houghton is becoming the face of the team, surpassing Kelly Smith, and their emergence as one of the best teams in the world adds to the excitement of the women's tournament.
USA over Argentina in field hockey
Argentina are the current world champions and favorites to win gold in London, but the Americans pulled a big upset to get back on track in field hockey.
Shannon Taylor was the lone scorer in the match as the US held on to win 1-0.
USA has beaten Argentina before, and that was considered a huge win. Doing it at the Olympics is even bigger and proves that the US are one of the best teams.
France stuns Australia in women's basketball
France did not even qualify for the Olympic Games in 2008. Australia finished with the silver in Beijing and entered as one of the medal favorites.
However, the French fought all game long and led the Aussies in what looked like a big victory. Then Australia hit a miracle half-court shot to force overtime.
Even with the momentum, they could not pull it off. France rebounded and took the victory, one of the biggest in their history. The upset came out of nowhere and puts Australia's back against the walls.
Honduras upsets Spain in men's soccer
Spain were one of the gold medal favorites. And for good reason. But the Olympic Games have not been kind to them at all.
Honduras came away with a monstrous victory, not only for them but for the entire field. Their win knocked Spain out of the tournament. A huge plus for the medal chances of their other quarterfinalists.
Sometimes, no matter how good your team is something just does not click. Whatever it is for Spain, they could not fix it at the Olympics and it cost them a chance at a big medal on the international stage. Honduras, on the other hand, gets a big boost by knocking off the talented Spaniards.
