Brendon de Jonge opened with a 6-under 65 in the Deutsche Bank Championship on Friday that allowed the Zimbabwean to wonder if this might be the week he breaks through with his first win.

De Jonge had a two-shot lead over nine players, including Rickie Fowler, Henrik Stenson, Luke Donald, Colt Knost, Kevin Chappell, Ian Poulter, Matt Jones, Harris Englishand and Charley Hoffman.

Jason Day, who needs a victory to become No. 1 in the world for the first time, played in the tougher morning conditions and shot a 68 at TPC Boston. He won The Barclays last week in New Jersey for his fourth victory of the year and third in four starts.

World No. 1 Rory McIlroy had a 70, while Jordan Spieth had his third straight round over par. Spieth had eight bogeys in a round of 75.

The 100 in the FedEx Cup standings qualified for the second event in the playoffs. The field will be cut to 70 for the BMW Championship on Sept. 17-20 and to 30 for the Tour Championship the following week.

Experts: Water likely not cause of sailor's infection

Medical experts and scientists said it's unlikely that a German sailor with a bacterial skin infection that's resistant to antibiotics contracted the illness in polluted Olympic waters.

Sailor Erik Heil fell ill after competing in a pre-Olympic test event held Aug. 15-22 in Rio's Guanabara Bay, into which dozens of rivers dump raw sewage.

Heil needed daily hospital treatment for multiple infections on his legs and hip. The Berlin hospital where he was treated said he contracted MRSA, a type of bacteria resistant to many antibiotics.

Heil, who said Thursday that he's now largely recovered, said he had never before had any such infections and felt that he got sick because of the water in Rio.

However, some top global experts on superbacterias said it's unlikely, though not impossible, that Heil got the infection from the water.

"You wouldn't expect to see somebody get MRSA from contact with water," said Dr. Pritish Tosh, an infectious disease physician and researcher at the Mayo Clinic in the U.S. "It's usually spread by skin contact."

Pollution, plants bother canoeists

Canoeists at an Olympic test event Friday complained about the polluted water at the venue, but were most outspoken about aquatic plants that tangled with their oars and rudders.

"I think really the most important thing they have to do is to work with the plants," German canoeist Franziska Weber said. "Because it's not fair. We work four years only for this moment, and to lose then because of plants — it's hard."

She described the water color at the Olympic canoeing venue as "red and brown. It's not the typical water color."

Weber joked that the effect on boat speeds of dragging weeds along was like "running up against a wall."

Her teammate Sebastian Brendel, a gold medalist three years ago in London, added: "This is just a test, but for next year they must clean the water."

Simon Toulson, general secretary of the International Canoe Federation, promised the weed problem would be cleared up for next year's Olympics. He said weeds had just been cut and had floated to the surface. Next year, he said, there will be time to collect the floating plants.

Toulson characterized the polluted water as presenting "very little risk" to athletes.

"The statistics point to the fact that falling in the water and drinking a little bit of it from this lake isn't a major health risk," he said.

He pointed to readings this week by the Rio state government that showed acceptable bacterial levels at the canoeing venue, partly because Rio has received little rain recently. When it rains, untreated sewage and debris gushes into the lagoon from hilltop slums that lack sanitation treatment plants.
