Roddick withdraws with illness; Federer wins opener in Toronto

Andy Roddick withdrew from the Rogers Cup on Tuesday in Toronto because of an undisclosed illness.

The eighth-seeded Roddick will be replaced by France's Paul-Henri Mathieu in the main draw. After losing in straight sets in the third round at Washington last week, Roddick said he "didn't feel right physically."

Roddick dropped to No. 11 in this week's ATP rankings, the first time since the rankings began in 1973 that there is no one from the U.S. in the top 10.

On the court, third-ranked Roger Federer, who had a first-round bye, beat Argentine challenger Juan Ignacio Chela, 7-6 (7), 6-3.

TRACK AND FIELD

Record-setting sprinter Bolt will not race again this year

Coming off a rare loss at 100 meters, Olympic and world champion Usain Bolt is cutting his season short, saying he won't race again in 2010 because of tightness in his lower back.

The Jamaican's manager, Ricky Simms, wrote in an e-mail that the world-record holder at 100 and 200 meters will have treatment to loosen his back, followed by rest, skipping IAAF Diamond League track and field meets in Zurich, Switzerland, on Aug. 19 and in Brussels, Belgium, on Aug. 27.

"It is better for me not to take any risks this year," Bolt said, according to Simms. "2011 and 2012 are very important, and I hope to be back fully fit and healthy. I look forward to coming back stronger next year."

Bolt hadn't lost an individual race in two years until Friday, when Tyson Gay of the United States beat him at the DN Galan meet in Stockholm. Gay ran 9.84 seconds, and Bolt finished in 9.97 -- almost four-tenths of a second slower than his record for the 100.

Also: Former Olympian Antonio Pettigrew, a sprinter stripped of a relay gold medal after admitting to doping, was found dead in the backseat of his locked car early Tuesday.

Authorities said they are unsure if his death was accidental or a suicide.

Chatham County, N.C., Sheriff's Maj. Gary Blankenship said Pettigrew's car was found parked by the side of a bridge. Blankenship said there was evidence that the 42-year-old Pettigrew had taken sleeping pills, and there was no sign of foul play.

Also: Arbor View High will host a memorial softball game today for former player Tiffanee Anderson, who died in a car accident in June.

Anderson, a 2009 Arbor View graduate, was a second team All-Central Valley Conference pick at Porterville (Calif.) College.

A slow-pitch softball game including many of Anderson's former teammates will follow.

The event will support the "Safe at Home" concept, which encourages students to head home before midnight and follow safe driving practices. The crash that killed Anderson and Inouye occurred at about 2:10 a.m.
