The powerhouse Jamaican track team packed a triple-punch at the London Olympics Thursday.
The world's fastest man, Usain Bolt, won the gold medal in the 200-meter sprint in 19.32 seconds. Teammate Yohan Blake finished second, and Warren Weir took the bronze.
Bolt is the first man to win the 100- and 200-meter sprints at two straight Olympics. He posted a record-setting time Sunday in the 100.
In the men's 800-meter final, Kenya's David Rudisha won the gold medal. His world-record time of 1 minute, 40.91 seconds was one-tenth of a second off the mark he set two years ago.
The U.S. men won gold and silver in both the 1,500-meter decathlon and the triple jump.
The Americans also pulled off gold medal victories in women's sports.
The U.S. football team gained revenge on Japan, 2-1, and the U.S. water polo squad beat Spain, 8-5.
In women's basketball, the heavily favored U.S. team advanced with an 86-73 win over Australia. The U.S., which will play France for the gold medal, is seeking its fifth straight Olympic title.
Meanwhile, one of the feel-good stories of the London Olympics, South African double-amputee runner Oscar Pistorius, had a scare.
His team failed to finish the 4-by-400 meter relay heat Thursday after a collision between one of his teammates and a Kenyan runner.
But South Africa was given a spot in Friday's final on appeal.
Pistorius wears prosthetics from below both knees. His father, Henke Pistorius, praised an earlier decision by officials to let his son run any part of the 4 by 400, not just the first leg.
"The change by allowing Oscar to run any of the legs and not forcing him to do the first, which is his weak point, the start is his weak point, is a wonderful change by the IAAF, it's a very sober thinking. I respect it," Pistorius said.
Also Thursday, women's boxing ended its Olympic debut with three gold medal matches.
Britain's Nicola Adams won the flyweight, Ireland's Katie Taylor took the lightweight, and American Claressa Shields captured the middleweight.
In other results, the German team of Julius Brink and Jonas Reckermann beat Brazil to win the gold medal in men's beach volleyball.
At Greenwich Park, Britain's Charlotte Dujardin won the individual dressage gold.
In total medals, the U.S. and China are still far ahead, with Russia in third. The United States and China are about even in gold medals.
