In the early stages of the 2012 London Olympics, China took an impressive gold medal lead over every other nation, but the United States forced it to relinquish that lead.
The track and field events gave the United States a significant boost in the overall standings, and they are now leading with 41 gold and 91 total medals.
With the Olympics ending on Sunday, August 12, it's safe to say that the U.S. will come out on top in both gold and total medals.
The U.S. led every nation in gold medals during the 1996, 2000 and 2004 Olympic games, but China was able to break that streak after leading the 2008 Olympics in Beijing with 51 gold medals.
Now, the U.S. will presumably reclaim their place as gold medal leaders.
But with the games still in progress, which events will add to their gold medal lead?
Team USA has been dominant in women's volleyball after winning 21 total sets and losing only two.
The U.S. swept the Dominican Republic in a dominant quarterfinals appearance, and they continued their excellence by sweeping Korea in the semifinals with a score of 25-20, 25-22, 25-22.
Their remarkable run will reach a conclusion when they face Brazil in the finals on Saturday, August 11 at 1:30 p.m. ET.
The U.S. were already able to convincingly defeat Brazil 3-1 during the preliminary rounds, so this is an ideal opportunity for the U.S. to expand their gold medal lead.
This one is obvious enough.
Team USA has a basketball team that consists of the best professional players in the entire world. Its dominance cannot be matched by the other nations, which were merely playing for the silver.
During the preliminary rounds, the Americans were able to hand Nigeria an embarrassing 156-73 defeat.
In the quarterfinals, they beat Australia 119-86, while stomping Argentina in the semifinals 109-83.
On Sunday, August 12, they'll take on Spain for the gold medal in what should be an easy victory for the United States.
Men's 5000-Meter Race
Lopez Lomong will be competing in the men's 5000-meter race final on Saturday, August 11 at 1:30 p.m. ET.
Lomong had a solid qualifying time of 13 minutes, 26.16 seconds. It was enough to launch him into the final round, but it was still only the fourth-best qualifying time.
The top qualifying time belonged to Hayle Ibrahimov of Ethiopia, who finished in 13:25.23.
Lomong has some odds to overcome, but he still offers the U.S. a legitimate gold medal opportunity.
