The wrestling pundits thought that the U.S. wouldn't bring home gold in freestyle wrestling. After the drubbing the Americans received at last year's world championships, gold did seem unlikely. The pundits were proven wrong in the very first weight class.

Henry Cejudo walked through the 55 kg (122 lbs) weight class, needing only two periods to finish off Japan's Tomohiro Nastunaga. In the first round, he defeated a previous world champion in Radoslav Velikov from Bulgaria, and then simply rocked Besarion Gochasvilli from Georgia and Azerbaijani Namiq Sevdimov. His gold medal puts him in the exclusive company of some of America's best wrestlers, including Dan Gable and Cael Sanderson.

Cejudo's win is going to cause a stir in the wrestling community because of how he reached the medal stand. Cejudo can be considered the Kobe Bryant of wrestling as he skipped the traditional route of going to college, and instead moved to the Olympic Training Center straight out of high school. Instead

On a beautiful Tuesday morning in Beijing, Misty May-Treanor and Kerri Walsh won over Brazil's team of Talita/Renata. The American pair make it look so easy, running and reaching balls that seem lost and scoring at will. They work so well togther that they seem to anticipate each other's every move. In the gold medal match, they will face the host country on Thursday morning in Beijing, though they don't know which pairing just yet. Tian Jia/Wang and Xue/Zhang Zi are set to face off at 10.

As Liu Xiang and Tyson Gay can tell you, peaking at the right time is essential at the Olympics. U.S. discus thrower Stephanie Brown-Trafton has clearly mastered that skill. After placing third at the Olympic trials, and never finishing higher than fourth at an international competition, she won gold in Beijing on her very first throw with a distance of 64.74 meters (212.4 feet). After that throw, she sat and watched several top competitors throw, but not come anywhere near her distance. Brown-Trafton, who dreamed of being like Mary-Lou Retton, now shares an important accessory with her idol: a gold medal.

Fifteen Greek athletes tested positive for the same banned substance in what the president of the Hellenic Olympic Committee calls organized crime. One of Greece's best hopes in track and field, Fani Halkia, was sent home just hours before she was scheduled to run in the 400m hurdles. Halkia won gold in Athens and was expected to be a top contender in these games.

This is not the first trouble Greece has had this year with doping. In March, 11 Greek weightlifters tested positive for a banned substance and were suspended, missing the these Olympics. The weightlifters, their coaches and medical personnel are now facing misdemeanor charges. Weightlifting is incredibly popular in Greece, so this story strikes me as sadly similar to BALCO.

Minos Kyriakou, president of the HOC, called on his government to find a solution to the doping problem in Greece. If the Greeks don't want a similar reputation to the East Germans in the 80's, they need to put an end to the problem now.

I was not pleased to learn that Nastia Liukin had been denied a gold in the uneven parallel bars due to a tiebreaker. Judging in gymnastics is under enough fire -- see Sacramone, Alicia -- so no fuel need be added.

Here is my question -- why not two golds? Ties result in two medals of the same color in several different sports. Two silvers were awarded in track and field in the women's 100m dash. Why is it necessary to break a tie in a sport that is overly subjective in the first place? If Liukin and China's He Kexin had routines that were truly identical in difficulty and execution, I see no harm in saying that and giving them both gold. If it is absolutely necessary to break the tie, do as other sports do and continue the competition. Have a tiebreaking routine with three or four required elements. Gold should not come down to an obscure reason.

If I had a gold to give out, I would give it to Liukin, not for her routine, but for her response.

"It’s nothing I can control, and

8:00 p.m. ET, NBC: In one of the more, ahem, interesting sports of the games, trampoline finals will be aired. No, you should not try this in the trampoline in your backyard. Gymnastics event finals in the women's uneven parallel bars, men's vault and rings will also be aired. Watch to see if Nastia Liukin can add to her medal total for the games.

10:00 p.m. ET, NBC: Misty May-Treanor and Kerri Walsh take their winning streak to the semifinals against Brazil, aired live for us all to enjoy.*

11:00 p.m. ET, NBC: Tune in to see if the U.S. can right the ship as the track and field action turns to men's steeple chase and 400m hurdles, and the women's pole vault.

*When I say all, I mean all in the Eastern and Central time zones. NBC doesn't think that live should mean live for the Mountain and Pacific time zones.

Today, U.S.A. softball again dominated, this time beating the host country of China. The Americans scored all nine runs in the first inning, while Cat Osterman and Jennie Finch combined for a one-hitter. This win rounded out preliminary play, with the U.S. finishing 7-0. The U.S. now moves into the semifinals, where they are joined by the Netherlands (who they've beaten), Japan (who they've beaten) and Australia or Venezuela or Australia (beat and beat). Of course, beating the same team twice is no easy feat. However, in these Olympics, this team has out scored their opponents 53-1 and thrown two no-hitters. No matter who they are matched up with, they are clearly the more dominant team.
