If Retief Goosen is in the hunt today, he's defying the odds. Since 1991 only one defending champ, Tiger Woods in 2001 and '03, has finished better than 40th. The last time Goosen was defending champ, he missed the cut. Goosen also missed the cut the last time the Open was held at Pinehurst No. 2, in 1999. Yet the South African is optimistic. "I wasn't particularly fond of it the first time I played it," Goosen said. "But I'm in a different frame of mind now." NBC 12:30 p.m.
Last year's tournament served as a coming-out party for Maria Sharapova, a relatively unknown 17-year-old ranked 15th in the world who won it all. "I didn't think about who was watching," she said.

Fat Tire Bike Week
Mardi Gras meets mountain biking as the world's longest-running bike festival celebrates its 25th anniversary in Crested Butte, Colo. The limbo contest is, some say, legendary.

A Stirring Comeback
Aston Martin is known more for being James Bond's preferred wheels (inset) than for its prowess on the track. The British automaker was out of racing for 15 years before returning in March, when David Brabham, Stephane Ortelli and Darren Turner drove the new DBR9 to a win at the 12 Hours of Sebring. The team led by Brabham and Turner will be favored in the world's greatest endurance race, the 24 Hours of LeMans. Speed Channel, check listings
