OAKVILLE, Ontario — Brandt Snedeker overpowered the par-5 18th hole Saturday in the Canadian Open to take a one-stroke lead over Canadian amateur Jared du Toit.

Snedeker hit a 378-yard drive and 121-yard approach to set up a 71/2-foot eagle putt that he holed for a 6-under 66. He had five straight birdies on Nos. 2-6, bogeyed 11 and 15, and birdied the par-5 16th.

Snedeker won the 2013 tournament at Glen Abbey. The 35-year-old American won the Farmers Insurance Open in February at Torrey Pines for his eighth PGA Tour title.

Du Toit, coming off his junior season at Arizona State, made a 40-foot eagle putt on 18 for a 70.

Pat Fletcher, born in England, was the last Canadian winner in 1954 at Point Grey in Vancouver, British Columbia. Carl Keffer is the only Canadian-born champion, winning in 1909 and 1914.

Phil Mickelson was the last amateur winner on the tour, in the 1991 Northern Telecom Open.

U.S. Open champion Dustin Johnson, tied for the lead after each of the first two rounds, was a stroke back after a 71.

Steve Wheatcroft and Alex Cejka were 7 under. Wheatcroft had a 64, and Cejka shot 69.

SENIOR BRITISH OPEN: Miguel Angel Jimenez opened a four-stroke lead in Carnoustie, Scotland, shooting a 7-under 65 in mild conditions to fall one short of matching the course record.

The 52-year-old Spaniard had a bogey-free round and was at 11-under 205 for the tournament, putting him in position for his first major title.

“Tonight, I’m going to do exactly the same thing I did the previous night,” Jimenez said. “I go with my friends, we go to a nice dinner with a nice bottle of Rioja, and after that I’m going to have a big, fat cigar with a nice malt whiskey.”

Paul Broadhurst (68), Wes Short Jr. (69), Tom Byrum (71) and Joe Durant (72) were tied for second.

LPGA: Charley Hull and surprising England grabbed the lead in the UL International Crown team event at Gurnee, Illinois, and the United States advanced with a sweep against Japan.

England won both of its matches against Thailand to finish at the top of its pool with nine points. The U.S. finished with seven points after victories by its two tandems – Lexi Thompson and Cristie Kerr, and Stacy Lewis and Gerina Piller.
