Roddick keeps up his strong pace

Already off to the fastest start of his career this year, Andy Roddick reached the fourth round at the Sony Ericsson Open in Key Biscayne, Fla., by defeating Dmitry Tursunov 7-6 (9), 6-2.

It was Roddick's 25th victory this year, most on the ATP Tour. It didn't come easily: The No. 5-seeded Roddick erased two set points in the tiebreaker and won the final three points in a stressful 75-minute first set.

U.S. qualifier Taylor Dent upset No. 15 Tommy Robredo 7-5, 6-3 and next plays No. 2 Roger Federer, who beat Nicolas Kiefer 6-4, 6-1. Dent and Roddick were left as the only American men in the field when No. 13 James Blake lost to No. 21 Tomas Berdych 6-4, 6-7 (3), 6-3.

There were two upsets on the women's side. No. 7-seeded Ana Ivanovic lost to No. 25 Agnes Szavay 6-4, 4-6, 6-1. No. 2 Dinara Safina was beaten by unseeded Samantha Stosur 6-1, 6-4.

South Korea, Canada call it a success The big winners coming out of the World Figure Skating Championships and gearing toward the Vancouver Olympics were South Korea and Canada. The United States? Not so much.

Kim Yu-na -- "Queen Yu-na" back home -- won South Korea's first gold medal, with the best score ever in a women's short program (76.12 points) and a 207.71 overall.

"I'm sure the whole globe shook," said Kim's coach, Brian Orser. "The whole country of Korea must be elated."

American ladies could use some inspiration. Rachael Flatt's debut at worlds was a fifth place that bodes well for her future, but U.S. champion Alissa Czisny was 11th. Their placements cost the Americans a third berth at the Olympics.

Draw keeps U.S. in World Cup lead Thanks to a dramatic draw, the United States will take a lead in its region into Wednesday night's World Cup qualifier against Trinidad and Tobago.

The Americans, ranked 17th in the world, rallied from two goals down in the final 20 minutes Saturday and forged a 2-2 draw at El Salvador, ranked 106th. The United States (1-0-1) is a point ahead of Mexico and Costa Rica in the North and Central American and Caribbean region.

Jozy Altidore started the comeback in the 77th minute, and Frankie Hejduk scored the tying goal in the 88th.

"We knew we had to fight back, and credit to the guys that we did it," U.S. captain Carlos Bocanegra said. "With this team, we never feel like we are out of the game."

At least 22 people were killed and 132 wounded at a stampede before a World Cup qualifying match in the main stadium at Abidjan, Ivory Coast.

Desire Tagro, the country's minister of the interior, said the stadium was overrun with people who pushed against each other, setting off the panic that led to the stampede ahead of the Ivory Coast-Malawi game Sunday.

Vonn takes U.S. slalom championship Lindsey Vonn, already a world champion, won a U.S. championship Sunday. Vonn captured the women's slalom title at the 2009 U.S. Alpine Championships in Girdwood, Alaska.

Vonn, a Burnsville native and winner of the World Cup overall title this season, and Julia Mancuso were tied after the first run in times of 51.00 seconds. Vonn completed the second run in 52.17 seconds for a combined time of 1:43.17. Sarah Schleper finished second in 1:43.27 and Mancuso third in 1:43.48.
