Williams sisters both advance

Serena and Venus Williams moved into the quarterfinals of the Western & Southern Open by handling the afternoon heat, humidity and wind at Mason, Ohio. The conditions were too much for Andy Murray.

Murray’s off day turned into the biggest upset of the tournament, a straight-sets loss Thursday that left him with hardly any hard-court time heading into the U.S. Open.

Murray lost, 6-4, 6-4, to France’s Jeremy Chardy, an opponent he had beaten easily the four previous times they had played. Murray had trouble controlling his shots on a breezy, 85-degree afternoon.

Roger Federer, Novak Djokovic, Mardy Fish and Juan Martin del Potro also reached the quarterfinals.

On the women’s side, Serena Williams won her 19th consecutive match -- her last 12 in straight sets -- by beating Urszula Radwanska of Poland, 6-4, 6-3. Williams hasn’t lost a set since the Wimbledon final, which she won.

Venus Williams beat Sara Errani, 6-3, 6-0, a quick match after two long ones the last two days.

Pettersson (62) has the lead

Carl Pettersson shot an eight-under-par 62 to take the first-round lead in the Wyndham Championship at Greensboro, N.C.

David Mathis and Tim Clark were a stroke back; Tom Gillis, Scott Stallings and Troy Matteson shot 64; and Matt Every had a 65 in the final event before the FedEx Cup playoffs.

Pettersson, a Swede who became an American citizen during the off-season, had his best round at the Wyndham since 2008, when he set the tournament record with a second-round 61 and went on to win in his adopted hometown.

Connecticut women’s basketball Coach Geno Auriemma said he has no interest in returning as head coach of the U.S. national team for the 2016 Olympics.

Auriemma met with reporters at Connecticut, five days after coaching the U.S. team to a fifth straight Olympic gold medal.

He said he was honored to get the job and ecstatic with the results but described his interest level in doing it again as “zero.”

“If you ask me right now, today, I would say it is somebody else’s turn,” he said.

Mike Krzyzewski returned as coach of the men’s team after the 2008 Games to lead it to another gold medal in London, but the U.S. has traditionally switched women’s basketball coaches after each Olympics.

After he brought grit and scoring punch in his first season in Philadelphia, the Flyers rewarded forward Wayne Simmonds with a six-year contract extension.

Simmonds was an instant fan favorite after coming over from the Kings in a trade for Mike Richards.

The 23-year-old Simmonds had career highs of 28 goals and 49 points.

Financial terms were not announced. Simmonds has one season left on his current contract.

Northwestern said the NCAA has ruled freshman center Chier Ajou, the tallest player in school history, eligible for the upcoming season.

Ajou moved from South Sudan to the U.S. in 2008 and there were reportedly some questions about the early years of his transcript. Those issues were apparently resolved and the school said Thursday he was cleared to play by the governing body.

The 7-foot-2 Ajou played two years for Culver (Ind.) Academies before attending prep school last year at St. Thomas More School in Connecticut.

Former Georgia football coach Jim Donnan is accused of orchestrating an $80-million Ponzi scheme, using his influence to get high-profile college coaches and former players to invest, the U.S. Securities and Exchange Commission said.

Donnan and business partner Gregory Crabtree, of Proctorville, Ohio, convinced investors to pour millions of dollars into a business they said was unique and profitable with huge potential and little risk, said William P. Hicks, associate director of the SEC’s Atlanta office.

The West Virginia-based liquidation company, GLC Limited, would buy appliances and furniture for resale, promising high rates of return that didn’t materialize, federal regulators said. The pair raised about $80 million from nearly 100 investors, but only about $12 million of that was used to buy merchandise for liquidation while the remainder was used to pay false returns to earlier investors or was spent by Donnan and Crabtree, the SEC said.

Donnan also funneled large sums to two of his adult children and a son-in-law, and regulators are seeking to recover at least some of that money, the SEC said.
