Four days of Olympic events are in the books and there have been some moments that seemed unfathomable as recent as last Friday.
Heavy favorites have fallen, mega-underdogs have prevailed, and new world records have been set by the unlikeliest of athletes.
Here are the five most shocking events that the entire Olympic village has been talking about as we enter Day Five of the London Games.
The Syracuse, NY native only had two events on her Olympic plate as she was overshadowed by bigger American names like Missy Franklin.
Vollmer ensured we paid attention by registering a 55.98-second 100m butterfly, shattering the record (56.06) previously held by Sweden’s Sarah Sjostrom.
Not only did she win a gold medal, but Vollmer is one of the few athletes of these 2012 Olympics to set a world record.
After failing to make the ’08 Games, Vollmer has redeemed herself in a way nobody saw coming.
You know the story.
Only two athletes from each country can advance and Wieber's U.S. teammates (Gabby Douglas and Aly Raisman) recorded better scores.
Wieber’s dream was shattered.
Despite finishing fourth overall, she was denied the opportunity to advance and the reigning world champion was left in shock.
This was truly one of the most emotional moments of the Olympics thus far.
She rebounded for a big performance in the team category, but the individual title has escaped her.
The Aussie swimming sensation has been an utter failure in the 2012 Games.
After winning gold in the 400-meter individual medley in the ’08 Olympics, she finished an extremely disappointing sixth in London.
She followed that up with a lackluster 200-meter individual medley which saw her finish fourth.
It comes as no surprise that Rice is now contemplating retirement.
The pair of Zhang Xi and Xue Chen entered London as the second-ranked duo in the world according to FIVB.
With their first opponent being a Russian squad ranked 29th, an easy victory appeared in store.
Instead, the Chinese team dropped the final two sets and fell to the sand in horror as the Russian duo of Anastasia Vasina and Anna Vozakova raised their fists in triumph.
Phelps put up an absolute stinker of a performance in the 400-meter individual medley, and a weak finish prevented him from landing gold in the 200-meter butterfly.
Yet he has rebounded in both the 4x200 freestyle and 4x100 freestyle, which coincides with the struggles of Lochte.
He blew the 4x100 free as the anchor, and placed fourth in the 200-meter free.
While both won gold in the 4x200 freestyle and Lochte nabbed gold in the 400-meter individual medley, the duo has failed to meet the lofty expectations set forth by the team.
Then again, with Phelps capturing medal No. 19 and setting a new Olympic record, you certainly can’t call the London Games a disappointment for the 15-time gold medal winner.
