Olympic Daily Preview - Tuesday, August 7th

American LoLo Jones returns to Olympic Stadium on Tuesday to take a shot a redemption in the 100-meter hurdles.

Jones was a favorite in this event at the 2008 Beijing Games and seemed on her way to a win before stumbling over the ninth of 10 hurdles in the final and finished seventh. She had the second-fastest qualifying time on Monday at 12.68 seconds. Australia's Sally Pearson had the fastest time and Americans Dawn Harper and Kellie Wells also qualified.

The big heats scheduled for Tuesday will see Jamaica's Usain Bolt and Yohan Blake take their turn at the 200m. Bolt edged his countryman to win his second straight 100m, but the two are slated to run in different heats and will need to advance to set up another head-to-head meeting.

The artistic portion of gymnastics at the London Games will conclude on Tuesday with four apparatus finals, two for the men and another pair of the women.

After her last-place finish in Monday's uneven bars final, American and current all-around gold medalist Gabby Douglas will look for a better showing on the balance beam. She will once again clash with Russia's Victoria Komova as well as 2011 world champion Sui Lu of China.

Best friends and teammates Aly Raisman and Jordyn Wieber will challenge for gold in the women's floor exercise, a routine that helped Raisman grab an all- around qualifying spot over Wieber. Romania's Catalina Ponor, the 2004 gold medalist, teammate and Olympic vault champion Sandra Raluca Izbasa as well as a pair of former world champions in Australia's Lauren Mitchell and Russia's Kseniia Afanaseva.

For the men, Japanese Yusuke Tanaka and Kazuhito Tanaka qualified first and second, respectively, on the parallel bars and will look to hold off 2010 world champion Feng Zhe of China. This event will feature nine gymnasts instead of the usual eight because of a tie between China's Zhang Chenglong and Hamilton Sabot of France.

On the horizontal bar, China's Zou Kai takes aim at his third gold of the London Games. Having already won the team competition as well as successfully defending his Olympic title on the floor exercise, he'll go against fellow favorites Epke Zonderland of the Netherlands and 2012 all-around bronze medalist Danell Leyva of the U.S.

The United States women's basketball team carries a 38-game Olympic winning streak into a quarterfinal matchup with Canada. The Americans have won four consecutive gold medals, and six overall.

If the U.S. wins, it could face a semifinal matchup against Australia, which has earned three consecutive silvers.

On the other side of the bracket, Russia plays Turkey and the Czech Republic takes on France, which went undefeated in group play.

The United States is guaranteed at least one medal in women's beach volleyball and could get two. Not so for the American men, who failed to place a duo in the Olympic semifinals, which will take place Tuesday.

Two-time reigning Olympic champions Misty May-Treanor and Kerri Walsh Jennings will play 2008 bronze medalists Zhang Xi and Xue Chen of China while U.S. teammates April Ross and Jennifer Kessy face Brazilians Juliana Silva and Larissa Franca.

On the men's side, Americans Jacob Gibb and Sean Rosenthal fell in the quarterfinals Monday to Latvia's Martins Plavins and Janis Smedins. Todd Rogers and Phil Dalhausser, the U.S. pair who won the 2008 gold medal, had already been knocked out. The semifinals will pit Plavins and Smedins against Brazil's Alison Cerutti and Emanuel Rego; and Germany's Julius Brink and Jonas Reckermann will play Reinder Nummerdor and Rich Schuil of the Netherlands.

Men's soccer resumes with a pair of semifinal matches, with Mexico battling Japan and South Korea squaring off against Brazil.

Brazil had to rally to top Honduras in its quarterfinal match and led the tournament with 12 goals. Three of those have come from the talented Neymar. Korea is coming of a victory on penalties over Great Britain and are winning behind 6-foot-6 goaltender Lee Bumyoung.

Mexico blew a two-goal lead to Senegal in the quarterfinals, but pulled together and earned a 4-2 triumph in extra time. Captain and goalkeeper Jose Corona was a key part of the win. Japan blanked Egypt 3-0 to advance to this match and are the only team to have yet give up a goal.

Russian's Ilya Zakharov led the men's 3-meter springboard after preliminaries with the final two rounds coming up Tuesday. He Chong of China was second in the first six dives Monday while American Troy Dumais, already a medalist here in his fourth Olympics, was third. American Chris Cowgill and Canadian Alexandre Despatie, a silver medalist in the event the last two Olympics, were also among the 18 divers who qualified for the semifinals. China has won all five diving events so far at the London Games after going 7- for-8 in Beijing four years ago.

Three events will be decided on the final day of track cycling -- the women's sprint and omnium, and men's keirin.

Great Britain's Victoria Pendleton will try for her second gold of these games, having already won the keirin last week. She has taken six of the last eight world titles in the women's sprint, and is the defending Olympic champion. Her biggest rival is Australian Anna Meares, whom she can meet in the final.

American Sarah Hammer and Great Britain's Laura Trott are tied for first heading into the second day of the omnium, a six-event competition.

In the men's keirin, Chris Hoy will try to earn his sixth gold medal and pass Sir Steve Redgrave for most in British history.

Russia's Natalia Ishchenko and Svetlana Romashina had the lead in synchronized swimming duets after the first free routine Monday and head into Tuesday's final as the favorites while medals will be awarded in equestrian after the dressage grand prix special.

The United States women's volleyball team, still pursuing its first gold medal, plays the Dominican Republic in a quarterfinal match. The Americans lost to Brazil in the gold medal match four years ago, and can only meet the defending Olympic champions in the final.
