A young U.S. women's soccer team has lots of work to do.

Playing without five regulars left at home to rest or rehab injuries, the United States struggled to a 1-1 draw Sunday with England in the Four Nations women's soccer tournament in Guangzhou, China.

The tournament is a tuneup for the World Cup in China in 7 1/2 months, and the Americans showed they can't overwhelm opponents with their second team.

The United States is rated No. 2 in the world behind Germany, and England is a distant No. 12. But it was difficult to tell which was which.

"Our young players, they gave us everything they could today," American coach Greg Ryan said. "But in fairness to them, I think England had the better of the game today."

The Americans went ahead 1-0 on Heather O'Reilly's header in the 17th minute off a pass from Natasha Kai, a Kahuku High and University of Hawai'i alum. But England equalized in the 47th on a strike by right back Alexandra Scott.

O'Reilly and Kai are among four or five forwards vying for spots on the World Cup team.

In Sunday's other game, Germany and China drew 0-0.

BARBARO SUFFERS SETBACK

Kentucky Derby winner Barbaro suffered a critical setback in his recovery Saturday when doctors decided to perform "risky" surgery after they were unable to keep him comfortable on his right hind foot.

When the colt developed an abscess in his right hind foot, below the leg bones that had healed after being broken in the Preakness Stakes last May, doctors couldn't keep him comfortable.

So to give the foot a chance to heal, they performed surgery to put Barbaro's right hind in an external skeletal fixation device, which consists of two steel pins placed through the cannon bone and connected to external sidebars that are in turn connected to a foot plate.

The weight is borne through the pins, creating the risk of the bone fracturing.

If the cannon bone were to break again, "It's pretty likely we would quit," chief equine surgeon Dean Richardson told USA Today on Sunday from the University of Pennsylvania's New Bolton Center, where Barbaro has been receiving treatment since his injury.

How likely is a break?

"It's possible. It's a small percentage, but it's often enough that you have to at least mention it," Richardson said.

MONTOYA, GANASSI ROLL

Juan Pablo Montoya gave his team the lead and Scott Pruett kept it until the finish Sunday for a victory in the Rolex 24 sports car endurance race at Daytona Beach, Fla.

Joined by Mexican driver Salvador Duran, Montoya added his first sports car title in the Daytona 24-hour race to a CART championship, the 2000 Indianapolis 500 win and seven victories in Formula One. Pruett, a veteran road racer, earned his second Daytona win.

Montoya will be back in three weeks to begin his first full NASCAR season in the Daytona 500.

This is the second straight year that Chip Ganassi's team has won this event. Former IRL champions Dan Wheldon and Scott Dixon combined with NASCAR driver Casey Mears to win the 2006 race.

Bode Miller went out five gates from the finish in his second run. U.S. teammate Ted Ligety, had a blistering second run to finish seventh.

KILDOW TAKES SUPER-G

Lindsey Kildow won a World Cup super-G Sunday on the course where she crashed out at last year's Olympics in San Sicario, Italy.

The American led at every split and finished in 1 minute, 30.06 seconds in the final race before the World Championships.

Renate Goetschl was second, 0.17 behind, but extended her lead atop the overall World Cup standings.

FISHER STOPS WHITE

Steve Fisher accomplished something few people have been able to do lately. Chris Burandt pulled off something no one had done before.

Fisher held off defending and Olympic champion Shaun White to win his second gold medal in snowboard superpipe, and Burandt launched an incredible 110-foot backflip on a snowmobile to take gold Sunday night at the Winter X Games at Aspen, Colo.
