A record crowd of 54,310 filled in to historic Franklin Field in Philadelphia on Saturday to watch the world's greatest sprinter compete in our nation's greatest track meet. Usain Bolt didn't disappoint.

The double-gold medalist and world record holder ran a blistering 8.79 in the final leg of the 4x100-meter relay at the event, much to the delight of thousands in attendance dressed in Jamaican yellow and green. As expected, Bolt and his teammates won the relay with ease. The United States team once again had trouble passing off the baton and finished a disappointing second place, just the second time that's happened in the past 11 years.

Check out Bolt's electrifying run below. That it's probably only the fifth or sixth most impressive race/relay he's run over the past three years speaks to how dominant he is in the world of sprinting:

This wasn't Bolt's first appearance at the Penn Relays. He ran in

For better or worse, Juan Antonio Samaranch led the Olympic movement from a period of turmoil into the corporate, multibillion-dollar behemoth it is today. The former IOC chairman died Wednesday at 89, leaving behind a legacy equal parts prosperous and controversial.

Samaranch guided the Olympics through a treacherous stretch in the 1980s and 1990s in which sports either rose to meteoric popularity (NFL, NBA, MLB) or lost its grip on the public consciousness (boxing, horse racing, NHL). It's easy to take for granted the success of the Games, but its standing as the world's premiere sporting event was greatly in doubt when Samaranch took over in 1980

Political boycotts in 1976, 1980 and 1984 threatened to derail the Games. With little money and the Olympics being used as Cold War leverage, it wouldn't have been inconceivable for the Summer Games to dissolve into irrelevance. Instead, Samaranch shored up political support for the quadrennial event, opened the doors to athletes from all

The Edmonton Oil Kings, as T.S. Quint in Mallrats put it, now in the framing business.

General manager Bob Green, while wending his way across Europe (http://www.vancouversun.com/sports/Green+travel+clouded+uncertainty/2925894/story.html) in search of a flight home, has dismissed (http://www.edmontonsun.com/sports/hockey/2010/04/20/13654816.html) both coach Steve Pleau and assistant Rocky Thompson. Edmonton won just 16 games all season, so perhaps it is not a huge surprise.

Coming Down The Pipe! (http://thepipelineshow.blogspot.com) ought to be a reliable go-to as the baby Oil search for a new bench boss.

In the OHL, the Peterborough Petes are intent (http://www.thepeterboroughexaminer.com/ArticleDisplay.aspx?e=2539034) on separating the coach and GM duties. The Petes seem prepared to go through the OHL draft on May 1 without replacements in place for Jeff Twohey and Ken McRae, the GM-and-coach combo who were left go in late March.

The international luge federation (FIL) released a report Monday that said "driving errors" caused the crash of Georgian luger Nodar Kumaritashvili during a training run prior to the Olympics. But it was a "complex series of interreleated events" that caused the 21-year old to be launched from the track into the steel supporting beam that killed him.

In layman's terms, the report says that Kumaritashvili over-steered one of the turns and tried to compensate for it on the next bank but couldn't hold on because of his speed and positioning. He lost control of the sled and went into the wall at such an angle that it caused the sled to catapult him into the air rather than contain him within the track, as would normally happen.

The FIL took great pains to praise Kumaritashvili's abilities and stated that he was deserving of his Olympic berth. Unlike some comments in the immediate aftermath of his death, this report suggests that this incident was a competent luger making a mistake rather

If you work at NBC and you're a "glass half-full" kind of person, then you might have been pleased by the news that the network exceeded financial expectations during the 2010 Olympics. But since nobody at NBC has any reason to be optimistic these days, the news that the Vancouver Games put the network $223 million in the red during the first quarter of the year is yet another blow to a sinking ship.

The figure is slightly less than the $250 million in losses NBC projected and vaguely smaller than the "couple hundred million" that Dick Ebersol had originally claimed his network would lose. The increased revenue was due to better-than-expected advertising sales in the weeks prior to the Games.

NBC did bring in about $800 million in revenue due to the Olympics but that was offset by production costs and the whopping $820 million it took just to get rights to air the Games.

Suits at the network will publicly praise the Olympic performance — the ratings were quite good, 14 percent better

Caster Semenya, the 19-year-old track star who was at the center of a worldwide gender controversy at last year's World Championships, wants to return to competitive running. She made the announcement the same day she was denied a chance to run in a meet in South Africa was denied because results from her gender verification test have not yet been released.

The defending world champion in the 800-meter insists she has done nothing wrong and believes she should be allowed to run while the IAAF continues to review test results that will determine whether Semenya is eligible to run as a woman. The tests were initially supposed to come back in October. Unconfirmed reports in the foreign press said Semenya's tests showed she had both male and female sex organs, but the IAAF has refused to confirm or deny the claims.

On Tuesday, Semenya tried to enter a meet in a city near Cape Town but was turned down despite pleas from her coaches and lawyers. She declined to speak to reporters, but

The International Olympic Committee has sent mixed signals on the future of women's hockey in the Winter Games.

According to IIHF president Rene Fasel, the IOC "does not have concerns" over early-round humiliations like Canada's 18-0 defeat of Slovakia in Vancouver, because the ticket sales are so strong. Yet IOC president Jacques Rogge made waves during the 2010 Games when he questioned the event's future in the Olympics if there isn't more parity internationally:

"There is a discrepancy there, everyone agrees with that," Rogge told reporters. "This is maybe the investment period in women's ice hockey. I would personally give them more time to grow, but there must be a period of improvement. We cannot continue without improvement."

Adrienne Clarkson, Canada's former Governor General, felt that despite Rogge's personal feelings on the sport he delivered "a slap in the face" to women with his questioning of the event's future. As she told the Globe & Mail:

"Women have been playing

In the World Figure Skating Championships that immediately follow the Olympics, the winner is quite often not the world's best skater, but the one who handles Olympic fatigue and the stress of a lengthened season the best.

Today in Torino, that was Japanese Olympic silver medalist Mao Asada. She won gold, beating Kim Yu-Na by nearly seven points.

Asada, who has spent much of her career in Kim's shadow, skated an aggressive, graceful routine. She completed two triple Axels, an incredibly difficult jump to perform even once, and had flawless footwork and spirals. Unfortunately, her second triple Axel was downgraded to a double, but that didn't keep her from winning gold.

Olympic champion Kim falters, still wins silver

Kim, fresh off her gold medal at the Olympics, had a disastrous World Championships. She came into the free skate in seventh place after making small but costly errors in the short program. In Saturday's free skate, she fell on a triple salchow and singled a planned
