Jamaica’s electrifying sprint king Usain Bolt, the fastest man in history, will tear up the track in one of the marquee events of the entire Games Sunday: the men’s 100m final.
A 21-year-old Bolt shocked the world during the Beijing Games when he crushed the competition and recorded a world record time. But two Americans plan on overtaking the Jamaican: 2004 Olympic champion Justin Gatlin and American record holder Tyson Gay. The 100m final begins at 4:50 p.m. ET and will be streamed live on NBCOlympics.com and replayed from 7 p.m. ET/PT on NBC.
The day's other big headliner was an historic first: After years of fighting to be included as an Olympic sport, women's boxing made its debut. Russia's Elena Savelyeva threw the opening punch against North Korea's Hye Song Kim, whom she beat 12-9.
The USA's first of three fighters to compete lost her match, and her shot at advancing, to a host country favorite. Quanitta "Queen" Underwood from Seattle, Wash. won the first round but quickly unravelled and ultimately lost to Liverpool's Natasha Jonas, 21-13, in London's sold-out Excel Center.
"You can't let the score get to you, but I think it got to me a bit," a teary-eyed Underwood said on NBC after the fight. "I threw all game plans out the window."
Two other women from Team USA will fight next week. Marlen Esparza, a 23-year-old flyweight from Houston, has her first bout on Monday and
, a 17-year-old middleweight from Flint, Mich., steps into the ring the following day.
Other news from the morning included the Williams sisters winning doubles to become the most decorated Olympic tennis players, and Great Britain's Andy Murray making a surprise win over Roger Federer to win singles' gold.
Stil to come: Former world champion Sanya Richards-Ross will compete for her first individual Olympic gold in her signature event, the 400m. She breezed through her first round heat crossing the finish line in 51.78 and is slated to compete in the 4x400m relay on August 10 and 11, and the individual 200m heats Monday.
Richards-Ross is the first American woman to advance to the Olympics in both the the 400m and 200m since Valerie Brisco-Hooks achieved the feat at the 1984 games in Los Angeles. The 400m is shceduled to start at 4.10 p.m. ET.
