The previous two days have seen the Americans pull ahead of China in both gold and overall medals. However, Day Eight will not hold buckets of gold for the USA.
If the U.S. wants to take medals away in they morning, they will have to rely on some upsets.
Corey Cogdell is the Americans' best shot at a medal in women's trap, but certainly not the favorite in the event. All of the American rowers will be facing an uphill battle. However, with a clean run, they can pull an upset to get on the podium.
The women's team epee squad will struggle to find the podium in London, but they may be just a bit inexperienced at this stage of their careers. It looks like Rio will provide a better opportunity to contend for gold.
In women's team pursuit, the American team qualified second—a distant second. Great Britain set a new world record with a time of 3:15.669 in the event. They will have to have a major mistake for another country to knock them off.
Three Americans will compete in the women's triathlon. None of them are favorites to medal, but there is also no dominant competitor in the event. Perhaps the U.S. can sneak in some hardware in this event.
Savannah Vinsant will represent the Stars and Stripes in trampoline. She qualified for the 2011 World Championships and finished seventh overall. It is unlikely that she can bounce, flip and twist her way on to the podium.
The U.S. will send the Bryan brothers to the gold medal match in men's doubles. They are one of the few favorites for the Americans on Day Eight.
Meanwhile, China will have a lot of athletes competing for medals. They have already guaranteed themselves three more badminton medals with a chance for four. That is only one sport. They can easily regain the overall lead on Day Eight.
The Americans will have favorites in three or four events, which could salvage Day Eight.
Serena Williams will face off against Maria Sharapova for the women's singles gold. Williams won Wimbledon only a month ago, and Sharapova was ousted in the fourth round. They will meet on the hallowed Wimbledon Centre Court.
Williams is the favorite in the tough match because she has been dominant at the Olympics. She crushed former No. 1 Caroline Wozniacki in the quarterfinals, and made short work of current No. 1 Victoria Azarenka in the semifinals. The destruction only took 64 minutes.
Team USA will also be a favorite in the men's and women's 4x100 medley relay. The men are the current world-record holders and qualified with the fastest time. The women are the defending champions, but do face some stiff competition from Australia.
The highlight of the night may come in the women's 100-meter dash. Carmelita Jeter will go for gold against Shelly-Ann Fraser-Pryce. Fraser-Pryce is the defending gold medalist in the event.
Also competing in the 100: American Allyson Felix, Jamaican Veronica Campbell-Brown and Trinidad and Tobago's Kelly-Ann Baptiste. Felix and Campbell-Brown will be underdogs in the 100, but are certainly fast enough to pull out an upset. If Felix can shock the field, that will definitely help the U.S. medal cause.
Overall, while the Americans have chances to medal on Day Eight, it will take a string of upsets to keep pace with China. They will need more success later in the weekend to make up for a slow day on Saturday.
