The Olympic action heats up today, so it's ime to see where we'd be best served to place our sports picks. Here's what you need to be watching today, and here is where we believe that the best sports betting opportunities lie.

We're not going to waste too much time. Though swimming is coming to an end, track and field has just started up again, to the delight of Olympic fans. 

Basketball 

Kobe BryantEarlier in the day, France had survived a late rally from Tunisia to win 73-69, while Russia toppled Spain 77-74 in what was one of the best games of the Olympics so far.

The USA team will battle it out with Lithuania and that should be one of the toughest tests of the competition for them so far. 

Elsewhere in group play today, Brazil takes on China as a 17-point favorite and Australia and Argentina are favored in their matchups with Great Britain and Nigeria respectively. 

Soccer 

The quarter-finals take place for the men today, with Japan already moving on in a relatively simple 3- victory over Egypt.

Mexico will play Senegal, while Brazil/Honduras and Great Britain/South Korea are the other last eight encounters on the schedule today. 

The Brazilians are humungous soccer betting favorites to advance, priced at -576 to win. The Brits, led by Craig Bellamy, are at +116 in the odds, with South Korea listed at +293. 

Tennis 

Can anyone stop Serena Williams? Doubtful.

Williams is storming through whoever she plays, her latest victim Victoria Azarenka in the semi-finals. She'll play Maria Sharapova in the final and is listed at a staggering -430 to get the gold over the Russian. 

In the bronze medal match, Azarenka was able to topple Maria Kirilenko 6-3, 6-4.

The doubles finals are today as well, with the Bryan brothers set to face the French pair of Michael Llodra and Jo-Wilfried Tsonga in the gold medal match. The Americans are -260 to win.

After likely winning the women's final, Serena Williams will pair with sister Venus to try and win the gold. No chance the Williams sisters lose this, as evident by their -690 pricetag.

Track & Field

We've got the discus throw, 400 meter semis and heptathlon for the women and the long jump and 10,000 meter final for the men. Don't forget about the most awesome event of the all either: the 20-kilometer walk!

The women's 100 meter final is on tap as well, with Shelly-Ann Fraser-Pryce the favorite and Carmelita Jeter right there too.

Swimming

Olympic TorchThe women have the 50 meter free and 4x100 meter relay, while the men deal with the 1,500 meter freestyle and 4x100 medley relay.

One would have to think the Americans should stroll to the gold in the women's relay, with Missy Franklin and Dana Vollmer among others set to swim.

Michael Phelps will be part of the men's relay team, which is priced at -600 to get the gold. Only Australia is even close to them in the swimming betting odds.

Beach Volleyball

It's fun to watch Misty May-Treanor and Kerry Walsh beat up on the competition and they should do so again against Netherlands today. Sportsbooks have them at -700 to win.

The men also get a taste of the action as they'll battle it out with a Russian team as -900 favorites.
