Wheelchair tennis' U.S. Open champion Lucas Sithole and his brother were dragged out of their car by four armed men in a late-night carjacking attempt in their native South Africa, the sport's national federation said Saturday. Both were unhurt, Wheelchair Tennis South Africa said, but had their cellphones stolen in the incident near a highway in Johannesburg at around 11.15 Friday night. Sithole's car was also damaged after the armed men emerged from a vehicle in front of the brothers on a highway onramp and forced them out of their car, WTSA said. He took up tennis and won the 2013 U.S. Open title, becoming the first African player to win a wheelchair tennis Grand Slam event.

Top-ranked Serena Williams is too wiped out to play in the Fed Cup against France on April 19-20, U.S. captain Mary Joe Fernandez said Wednesday. ''She is mentally and physically exhausted and needs a break, so bad timing for us, unfortunately,'' Fernandez said in a telephone interview. She's been going hard the past couple of years and needs to get refreshed.'' Neither of the Williams sisters was on the roster submitted Wednesday by Fernandez for the upcoming World Group playoff, to be played on an indoor hard court at Saint Louis University. ''Serena and Venus both wanted to play,'' Fernandez said, ''and I was looking forward to having them.'' She called the 32nd-ranked Venus' absence the result of ''an innocent mistake'': According to Fernandez, Venus signed up for the hard-court tournament being played April 14-20 at Kuala Lumpur, Malaysia, not realizing that was the same week as the Fed Cup matches.
