So far, there's only one opponent that can really beat Bolt - and that's time.
Great Britain's Mo Farah won the Olympic 5,000 metres gold medal to complete the distance double-double, having won the 10,000m earlier in the week after claiming both titles in 2012.
In the other semifinal, Australia plays Serbia. Poor defensive efforts were responsible for both of those results, but then team US held Argentina to 78 points in the quarterfinals and Spain to 76 in the semifinals (though it managed only 82 in that contest). What a privilege to see this man collect a fourth Olympic medal in style. She was recruited to try triathlon seven years ago and is now the top woman in the sport. Another victory and she'll become the United State's first-ever two-time Olympic boxing gold medalist.
Shields, 21, who grew up in Flint, Mich., also beat Fontijin back in May to win her second consecutive world championship. Women's boxing was added to the Olympics in 2012.

He closed out the Rio Games with a lifetime total of 28 medals - 23 gold, 3 silver and 2 bronze.
"The atmosphere at the GB house has been incredible in the village", said Mo Farah, who won gold for Britain in the 5,000- and 10,000-meter races to match the feat he pulled off at London in 2012.
The United States didn't qualify in team handball, men's or women's, and hasn't in quite some time.
Bolt romped in the 200 meters Thursday night, but finished in 19.78 seconds, .59 short of his own world record. A victory would give Brazil the only trophy it hasn't won in soccer.
