Usain Bolt will get one more chance to add to his gold medal haul at the London Games, as he anchors the Jamaican 400- meter relay team Saturday on the final night of track and field action at Olympic Stadium.
Bolt owns five Olympic medals -- all gold -- and has claimed two of them here in London, winning both the men's 100 and 200 meters. The 25-year-old is the only man to have won gold in the 100 and 200 at back-to-back Olympics.
Yohan Blake, who finished second in the 100 and at 200 the London Games, is slated to run the third leg of Jamaica's relay on Saturday and hopes to have Bolt in gold medal position at the final handoff.
With Bolt running the anchor four years ago in Beijing, Jamaica won its first gold in the sprint relay.
The United States hasn't won the 400-meter relay since the 2000 Sydney Games and failed to medal in Beijing after dropping the baton.
This year's edition of the American men's team will be anchored by Justin Gatlin, winner of the bronze medal in the 100m at the London Games. The U.S. posted a national record time of 37.38 seconds in Friday's qualifying heats.
Blake ran in qualifying for Jamaica on Friday, but Bolt did not. The Jamaicans were still second-fastest in heats and only .01 seconds behind the U.S. time.
The women's 1,600-meter relay will be staged on Saturday and the Americans also recorded the fastest qualifying time for that final.
Following his captivating win in the 10,000 meters, Great Britain's Mo Farah will try to achieve the distance double in the 5,000. Farah won the 5,000 at the world championships last year, but will also face stiff competition Saturday.
American Galen Rupp, who took silver in the 10,000, will also line up, alongside Ethiopian Dejen Gebremeskel and Kenya's Edwin Soi.
Russian Mariya Savinova and South African Caster Semenya headline the field for the women's 800 meters. Savinova beat Semenya at the 2011 world championships, but Semenya had the fastest qualifying time earlier this week. American Alysia Johnson Montano will also run in the final.
Medals will also be awarded in the field events for women's high jump and men's javelin.
Additionally, two race walking events take place Saturday -- a 50-kilometer event for men, and a 20km race for women.
The United States will be seeking an unprecedented fifth straight Olympic gold medal in women's basketball on Saturday against a country, France, making its first appearance in a women's final.
The U.S. carries a 40-game Olympic winning streak dating to the bronze medal match in 1992, the last time it failed to win gold. The French team has also gone undefeated here and is guaranteed its first ever medal in Olympic women's basketball.
Australia and Russia will play for the bronze medal at North Greenwich Arena before the U.S. and France take the court.
Brazil and Mexico will be in search of their first Olympic soccer gold medal Saturday in the men's final at Wembley Stadium. Mexico has never medaled in men's or women's soccer at the Olympics while Brazil's men's team has two Olympic silvers and a bronze. South Korea won the bronze medal Friday with a 2-0 victory over Japan.
Reigning world champion Qiu Bo and Chinese teammate Lin Yue were first and second in preliminary dives in the men's 10-meter platform, which will have its semifinal and final rounds Saturday.
They will try to extend China's dominance over diving at the London Olympics. The country has won six of the seven diving events here after going 7-for-8 in Beijing four years ago.
The diver who prevented a Chinese sweep in 2008, Australian Matthew Mitcham, is the reigning champion in the platform and finished ninth in the prelims.
German Sascha Klein and Martin Wolfram were third and fourth behind Qiu and Lin while Americans Nicholas McCrory and David Boudia also qualified for the semifinals. Only the top 18 divers out of 32 made it through. McCrory was eighth and Boudia got the 18th spot by 4.2 points. Canada's Riley McCormick qualified 11th but teammate Eric Sehn was eliminated in 29th.
Great Britain's Tom Daley moved on in the 15th spot. Daley and partner Peter Waterfield finished fourth in the synchronized platform event here -- an outcome that drew headlines for what happened afterward when police arrested a 17-year-old for tweeting Daley that he let his deceased father down. Daley's father died of brain cancer last year.
Saturday's gold medal match in women's volleyball will be a sequel to the 2008 final, when Brazil beat the United States. The No. 1-ranked Americans are the favorite this time around, however, and have rolled through the tournament so far without a loss. Japan and South Korea will play for the bronze.
Medals in women's handball will also be handed out Saturday with reigning Olympic champion Norway looking to defend its title against Montenegro, which has made the gold medal match for the first time. South Korea and Spain will compete for the bronze.
The sailing competition ends Saturday with the conclusion of the women's Elliott 6m match racing event. Australia, which was dominant in the round robin stage, takes on Spain for the gold medal after Finland and Russia sail against each other for bronze. The competition has been somewhat stunted, as light winds Thursday and Friday forced officials to cancel lower-placement matches and postpone others. The semifinals were shortened to three-race matchups, down from five.
The women's cross-country mountain bike race takes place, and Canadian Catherine Pendrel will line up as one of the primary favorites. She is the reigning world champion and has won three world cup races this year. American Georgia Gould, the Czech Republic's Katerina Nash and France's Julie Bresset should also be in the mix for medals.
Meanwhile, five medals will be handed out in men's boxing.
No. 1 seed and defending champion Zou Shiming of China will be the favorite against Thailand's Kaeo Pongprayoon in the light flyweight division and John Joe Nevin will look to become the third Irish boxer to win an Olympic gold medal in his bout with Great Britain's Luke Campbell in the bantamweight division.
Cuba's Roniel Iglesias Sotolongo will fight Ukrainian Denys Berinchyk for the Olympic light welterweight title while Brazil's Esquiva Falcao Florentino and Japan's Ryota Murata will renew their semifinal bout from last year's world championships in the middleweight division. World champion Oleksandr Usyk of the Ukraine will meet Italian Clemente Russo for the heavyweight gold.
Additionally, medals will be awarded for the women's 67kg and men's 80kg weight classes in taekwondo, as well as the men's 55kg and 74kg freestyle wrestling divisions.
The inaugural 200-meter canoe sprint finals will close out Olympic events on Dorney Lake with four races set to take place.
One highlight will be the first ever women's 200m single kayak final, while the men will engage in 200m races in the canoe single as well as kayak single and double.
The 200m races for men are replacing previous 500m races at the Olympic Games.
Russia heads into the individual all-around of rhythmic gymnastics with the top two qualifiers in Evgeniya Kanaeva and Daria Dmitrieva.
Kanaeva, a three-time world champion, is trying to become the first rhythmic gymnast to win two Olympic gold medals in the all-around after also taking the title at the 2008 Beijing Games. She trailed Dmitrieva after the first day of qualifers, but took the lead with a strong showing on Friday.
Belarus' Liubou Charkashyna fell to fifth after struggling in her two routines, passed by both Aliya Garayeva of Azerbaijan and Bulgaria's Silviya Miteva.

It faces a tough task against defending Olympic champion Germany, which downed Australia to reach the final.
Great Britian will play the world No. 1 Aussies hoping to medal for the first time since the 1988 Seoul Games.
The 36-man modern pentathlon field gets underway on Saturday, an event that features athletes battling in five sports in one day.
